digitalis lanata family

In 964 cases (3.4% of all admissions), adverse reactions were considered to be the cause of admission. The Plants Database includes the following 6 species of Digitalis . Frequent non-cardiac reactions include gastrointestinal effects (anorexia, nausea, vomiting, and diarrhea), central nervous system effects (drowsiness, dizziness, confusion, delirium), and less commonly visual effects (color vision abnormalities, photophobia, and blurred vision). Cardiac signs may be delayed, heart becomes hyperirritable, LD50 (rats) 560 mg/kg b.w. In addition, users can learn about the location of vouchered specimens and see images to get a better visual for each plant. Plantaginaceae. The genus has recently migratedfrom the figwort family (scrophulariaceae) to the plantain family(plantaginaceae) – along with its cousins the penstemons – butmost references still place them in their former taxonomical position. (i) Shape: sessile, linear, and lanceolate. Gastrointestinal complaints (19%) were the most common, followed by metabolic and hemorrhagic complications (9%).

The New York Flora Atlas is a source of information for the distribution of plants within the state, as well as information on plant habitats, associated ecological communities, and taxonomy. Prevention of further exposure to plant-origin cardiac glycoside includes removing the plant parts, particularly from patients with suicidal tendencies. The polycyclic diterpene alkaloids act as neuromuscular blocking agents, and the other two classes of steroidal alkaloids are solanum (a cholinesterase inhibitor) and veratridine (a hypotonic) (Schep et al., 2006). The raw material of lanatoside C for the preparation of the reference standard is usually examined by HPLC. 3. The original family name was Veronicaceae until 1789 when the family name became Plantaginaceae. Group: Dicot Rank: species Kind: Name of a new Taxon Herbarium Placement: Monsanto, 3rd, C, 257 Authors: Ehrhart, Jakob Friedrich. The patients whose serum digoxin concentrations were over 3.2 nmol/l (2.5 ng/ml) were slightly older (78 versus 73 years) and had higher serum creatinine concentrations (273 versus 123 μmol/l) than those whose plasma concentrations were below 3.1 nmol/l. 1. However, color vision disturbances associated with cardiac glycosides are due to inhibition of Na/K-ATPase [15]. Digitalis lanata, like some other foxglove species, is highly toxic in all parts of the plant. It is differentiated into palisade and spongy parenchyma. Scrophulariaceae – Figwort family Genus: Digitalis L. – foxglove Subordinate Taxa. Digoxin also reduces sympathetic nerve activity, renin-angiotensin activity, circulating catecholamines, and regulates baroreceptor function by increasing vagal tone (vagomimetic effect). A drug interaction was a contributory factor in 10 cases. The most strongly argued case is that digitoxin is preferable to digoxin in patients with renal insufficiency, since digitoxin is metabolized and digoxin is excreted by the kidneys. Digitalis lanatacan be cultivated for its bell-shaped flowers, but let loose, it can become a noxious weed. Ehrh. Pharmacognostic Features Botanical origin: Digitalis purpurea L Family: Scrophulariaceae English name: Foxglove, Fairy cap Part used: Dried leaves Chemical class: Digitalis glycoside Species of digitalis Two known species of Digitalis are: 1) Digitalis lanata Ehrh. This is the conserved name under the International Code of B… Plants known to contain cardiac glycosides include Digitalis purpurea, Digitalis lanata (foxglove; Figure 47-4A), Nerium oleander (oleander; Figure 47-4B), Strophanthus gratus (ouabain), Thevetia peruviana species (yellow oleander); Convallaria majalis (lily of the valley), Urginea maritima, and Urginea indica (squill). Plants contain on average a dozen different compounds that may cause cardiotoxicity, but two are of primary importance for inducing toxicity when consumed—glycosides and alkaloids. It consists of the dried leaves of Digitalis lanata J. F. Concepts After adjustment for various factors, prior digoxin use (OR = 11; 95% CI = 5.7, 23) and pulse over 100/minute (OR = 2.33; 95% CI = 1.1, 4.9) were associated with inappropriate digoxin use. Content Guidelines 2. Poisoning from ingestion of the seeds of Thevetia peruviana (yellow oleander) can be treated with oral multiple-dose activated charcoal, which reduce mortality [26]. D. lanata … Of 603 adults aged 79 years, of whom 59% were women and 18% African-American, 376 patients (62%) were discharged taking digoxin, and 223 (37%) had no indication for its use, based on the absence of left ventricular systolic dysfunction or atrial fibrillation [20]. Definition (CSP) extract from genus of toxic herbaceous Eurasian plants of the Scrophulaceae which yield cardiotonic digitalis glycosides; most useful species are Digitalis lanata and D. purpurea. It is associated with freshwater habitat. Calcium oxalate crystals are absent. Lanatoside is acetylated products of purpurea glycosides. Plantaginaceae was not originally placed in the order Lamiales, but in the order Plantaginales. Single layered, covered with a thick cuticle, cells have wavy and thick walls; two kinds of trichomes are seen, multicellular, uniseriate covering trichomes and glandular trichomes with unicellular stalk. Of the 1.33 million exposures to nonpharmaceutical substances reported to the American Association of Poison Control Centers in 2006, only 1405 (0.1%) were due to exposures to cardiac glycoside-containing plants.8 In Sri Lanka and India, increased suicidal or parasuicidal ingestion of yellow oleander (Thevetia peruviana) is associated with case fatality of 5 to 10% in untreated victims.9 Toxicity occurs with serum digoxin levels of >15 ng/ml. The species is hermaphrodite (has both male and female organs) and is pollinated by Bees. Unlike digoxin toxicity, serum magnesium concentrations are less likely to be affected in yellow oleander poisoning. It is a species of foxglove. Café Crème is an elegant and alluring beauty. Copyright © 2020 Elsevier B.V. or its licensors or contributors. TOS 7. Digitalis is typically a biennial plant but may be annual or perennial depending on the species. Digitalis lanata. The cardiotonic properties of this plant have been used both therapeutically, as well as in poisoning, since ancient times. M. Lai, B. Lü, in Comprehensive Sampling and Sample Preparation, 2012. The labeling density of a DNA with a DIG-labeled nucleotide is every 20th to 25th nucleotide in general. Next to glycosides, alkaloids from plant ingredients play an important role in cardiac toxicity. There are wooly hairs on the purple tinged stem. After drying leaves are stored in moisture proof container. Digitalis lanata. Digoxin, from Digitalis purpurea and Digitalis lanata (foxglove), the ingredient of digitalis, is used to enhance myocardial contractility but has a narrow therapeutic index. Copyright 10. Agricultural production is the only economically feasible process to obtain these cardenolides and thus, investigations on methods of isolation and analysis are of interest. Ancient Egyptians and Romans long used cardiac glycoside-containing plants as emetics and for heart ailments. The DIG-labeled nucleotides may be incorporated, at a defined density, into nucleic acid probes to produce an optimally sensitive hybridization probe. Content Filtrations 6. Hybridized DIG-labeled probes may be detected with high-affinity antidigoxigenin (anti-DIG) antibodies that are conjugated to AP, peroxidase, fluorescein, rhodamine, or colloidal gold. These herbs may produce cardiac arrhythmias, mainly ventricular ectopics, ventricular tachycardia, as well as various degrees of arterioventricular (AV) blocks. Estimates vary widely from study to study, but in large prospective studies of hospital inpatients the frequency of digitalis toxicity has been as high as 29% [16]. Some plants that contain cardiac glycosides. Policies that counter potentially harmful botanical dietary supplementation are advocated.11, In Meyler's Side Effects of Drugs (Sixteenth Edition), 2016. An are shaped vascular bundle is present more towards the ventral surface (upper epidermis) of the midrib. LD50 (goats) 330 mg/kg, b.w., in sheep 110 mg/kg b.w. Their toxic effects on the myocardium may be due to excessive inhibition of cardiac Na/K-ATPase, although there is also evidence that effects on the nervous input to the heart may be involved [14], and it is not clear to what extent such an effect is mediated by inhibition of Na/K-ATPase. Symptoms of digitalis poisoning include nausea, vomiting, dilated pupils, severe headache, eyesight problems, and convulsions at the critical level of toxicity. The digitalis consists of dried leaves of Digitalis lanata. This sodium in turn is exchanged for extracellular calcium, raising the concentration of available calcium ions within the myocardial cell and thus mediating increased contractility. In another study of this sort, serum digoxin concentrations were measured in 2009 patients [18]. It is characterized by a thick, cylindrical, downy stem that reaches a height of up to 2 m. Leaves form a thick rosette during the first year of growth. 79, pregnenolone; 80, isoprogesterone; 81, progesterone; 82, 5β-pregnane-3, 20-dione; 83, 5β-pregnane-3β-ol-20-one. Unfortunately, the authors did not report the frequency of adverse effects, and it is not therefore clear whether patients in whom digoxin is used inappropriately are more or less likely to suffer adverse reactions. Nucleic acids can be labeled by DNA or RNA polymerase and terminal transferase, or chemically with DIG-NHS ester or with DIG Chem-Link. Flower: Flowers are in an elongating spike at the top of the plant, blooming from the bottom of the spike first. Although digoxin excretion also varies from patient to patient, it can at least be gauged by measurement of creatinine clearance. Alkaloids are metabolites, nontoxic to the organism producing them and toxic to foreign organisms. It grows wild throughout Europe. Additionally, they cause hemorrhage, myocardial lesions, and myocarditis (Botha, 2013). It was found that toxicity can occur within the therapeutic range with old patients being especially at risk of developing digoxin toxicity [31]. Figure 7. Below the upper epidermis and above the lower epidermis are seen thin strips of collenchymas. There were no differences between the groups in serum potassium, calcium, or magnesium concentrations, but the serum creatinine concentration was significantly higher in those who had definite and possible toxicity. The yellow oleander tree contains phytochemicals, known as cardenolides, which are capable of exerting positive inotropic effects on the heart. It is a type of cardiac glycoside. In a Turkish case, the ingestion of two bulbs or Urginea maritima as a folk remedy for arthritic pains was sufficient to result in fatal poisoning [33]. Two layered, loosely arranged and does not form a continuous band throughout as it is absent above the vascular bundles of lamina. The cardiac glycosides that have been used therapeutically are listed in Table 1. When other results were omitted in cases in which the sampling time was not known, there were 138 evaluable patients, of whom 83 had clinical evidence of digoxin toxicity, an overall incidence of 4.1%. The Lily family contains the alkaloid veratridine, a depolarizing agent that causes persistent opening of voltage-gated Na+ channels and reduces channel conductance by three-quarters (Table 14.1). Family. Digitalis lanata Ehrh. It is a photoautotroph. Ehrh., belonging to family Scrophulariaceae. Bradycardia and/or tachycardia, ventricular fibrillation, In sheep depression of ST on ECG, hyperkalemia, serum potassium may increase twofold, second-degree AV-block. Clinical manifestations of poisoning range from mild to potentially fatal. Armelle T. Mbaveng, ... Victor Kuete, in Toxicological Survey of African Medicinal Plants, 2014. Fab fragments of antidigoxin antibody have also been used to treat oleander intoxication, for example in a 7-year-old child [29] and a 44-year-old man [30], but in a randomized controlled trial did not affect mortality [31]. Image 5548411 is of Grecian foxglove (Digitalis lanata ) flower(s). Various herbal or herbal/mineral combinations used in traditional medicine are currently being used around the world as therapeutic remedies for common ailments. The drugs most commonly associated with adverse effects were non-steroidal anti-inflammatory drugs (n = 30), psychotropic drugs (n = 14), and digoxin (n = 5). In addition, cardiac glycosides have vagotonic effects, resulting in bradycardia and heart block (Beasley, 1999; Liu et al., 2010). Glycosides, with a digitalis-like effect, are lethal in domestic animals upon ingestion of 100–200 mg/kg of body weight (b.w.). Wooly foxglove is a vigorous and indispensable perennial for areas ravaged by deer. Of the 82 in whom the blood sample had been taken at an appropriate time, 59 had electrocardiographic or clinical features of digoxin toxicity. Cardenolide structure (76–78) and biosynthesis (79–83). In a multicenter survey, conducted between 1988 and 1997, of 28 411 patients, mean age 70 years, admitted to 81 hospitals throughout Italy, 1704 had adverse drug reactions [19]. Alternatively, unconjugated anti-DIG antibodies and conjugated secondary antibodies may be used. I. Wawer, in NMR Spectroscopy in Pharmaceutical Analysis, 2008. The D. lanata 3βHSD expressed in E. coli uses pregnenolone but not cholesterol as a substrate (Figure 10).246 A malonyl-coenzymeA:21-hydroxypregnane 21-O-malonyltransferase involved in the formation of the butenolide ring of digitoxigenin was reported in leaves of D. lanata.251 Cardenolides, produced in laticifers of Apocynaceae,252 have been looked at in ecological approaches of plant–insect interactions to illustrate the defense-escalation theory and the evolutionary trends of secondary metabolism moving toward a decline of plant chemical defence strategies.253. The New York Flora Atlas is a source of information for the distribution of plants within the state, as well as information on plant habitats, associated ecological communities, and taxonomy. For instance, when an anti-DIG antibody and AP-conjugated to secondary antibody is used, the results of ISH can be visualized with 5-bromo-4-chloro-3-indolyl-phosphate (BCIP) and nitroblue tetrazolium salt (NBT) substrates, as in immunohistochemistry. 2. Detection of digoxin poisoning by plant-origin cardiac glycoside is difficult and complicated to interpret, and analyses may not detect all the plant forms of cardiac glycosides.10 Botanical identification of the suspected plant is helpful. Digitalis - from the modern Latin genus name of the foxglove, from digitalis (herba)' (plant) relating to the finger. However, their toxicity was only recognized in 1785 after the seminal publication of William Withering.7 In other countries, oleander has been used as a medicinal plant for the treatment of leprosy, ringworm, malaria, and sexually transmitted diseases, and as abortifacients and appetizers. Distinct phloem tissue can be seen on the dorsal surface and well developed xylem tissue towards the ventral surface of the midrib is seen thin. Family: Scrophulariaceae Geographical source: ADVERTISEMENTS: It is found in European countries, England, France, … As a group,they are known as the foxgloves, named for their most popular species, thecommon foxglove: Digitalis purpurea. fatal for horses, cattle, Necrosis of myocardial tissue, inflammation of the heart; horses, rabbits, goats, ostriches affected, Sheep fed 2.5 g/kg b.w. Digitalis lanata, the plant harvested in Brazil is the industrial source of digoxin and lanatoside C, used in the treatment of congestive heart failure. After collection leaves are dried immediately at temperature below 60 C and they contain no more than 5% moisture. 2) Digitalis purpurea L. Digitalis (Scrophulariacea e) 2. Yellow oleander (Thevetia neriifolia) produces seeds which are highly poisonous and contain three glycosides – thevetin, thevetoxin, and peruvoside. Plants that harbor alkaloid toxins include Larkspur, Yew, Monkshood, Ground Hemlock, and Death Camas. Overdose induces ECG changes such as ST-depression, T-wave inversion, PR-interval prolongation, and QT-interval decrease thereby leading to the signs of cardiac toxicity. In outpatients the figure may be as high as 16% [7]. This labeling density ensures optimal steric interaction between the hapten and anti-DIG antibody conjugate, which is large enough to cover about 20 nucleotides. It has a self-supporting growth form. Despite its wide therapeutic use, compound 2 has a low therapeutic index and toxicity is common. Plant-specific determinants of morbidity related to cardiac glycoside poisoning include plant species, part of plant ingested, specific type of glycoside contained, and concentration of glycoside in plant parts ingested, but mortality is rare. Naturk. There are thousands of cases of intoxication reported each year, some of which have a fatal outcome (Eddleston et al., 1999, 2000a,b; Fonseka et al, 2002). The digoxin molecule is composed of a sugar and a cardenolide; its molecular formula is C41H64O14 and its molecular weight is 780.95 Da. The purity and authenticity of lanatoside C can also be attested by solid-state NMR. The effect of magnesium concentrations on toxicity and outcome is not known (Langford and Boor, 1996; Rajapakse, 2009). Each spikes is tightly packed with small tubular flowers that have a brown/amber netting pattern on the outside. The mean age of the patients was 69 years. There are major pharmacokinetic differences among the different cardiac glycosides, the principal difference being between those that are mainly excreted via the kidneys (for example digoxin, metildigoxin, β-acetyldigoxin, ouabain, and k-strophanthin) and those that are mainly excreted via hepatic metabolism (including digitoxin, gitoxin, pengitoxin (16-acetyldigoxin), and gitoformate). Family: Scrophulariaceae Genus: Digitalis Species: Digitalis lanata; Distribution Table Top of page. Digitalis lanata: sepals 10-15 mm long and mostly 6-9 mm wide, and petals usually purple to pale pink or white (vs. D. purpurea, with sepals 7-10 mm long and 1-2.5 mm wide, and petals white to pale yellow). Alkaloids exhibit cytotoxicity against cells of foreign organisms. There is a large amount of evidence that the mechanisms of action of cardiac glycosides are mediated directly or indirectly by inhibition of the sodium/potassium pump enzyme, Na/K-ATPase [13]. Numerous plants worldwide contain cardiac glycosides that have been used both therapeutically as herbal formulations and for the purposes of self-poisoning. Digitalis is a genus of a couple dozen or so species (wikipedia saysabout 20, GRIN lists only about 12 currently accepted species). These results suggest that digoxin toxicity is still very common and confirms the increased risk in elderly patients, patients with renal impairment, and patients taking drugs that may interact with digoxin. For this reason they are generally known as “digitalis.” Most other cardiac glycosides, such as ouabain and proscillaridin, do not come from foxgloves but are nevertheless also commonly called “digitalis.” Thus, the terms “cardiac glycoside” and “digitalis” are used interchangeably. Table 14.1. Species. Genus. The drugs most often responsible were diuretics, calcium channel blockers, non-steroidal anti-inflammatory drugs, and digoxin. Details are given in Table 2. However, it varies with dysrhythmias, and for paroxysmal supraventricular tachycardia with block may be as high as 50% [7]. The plant is a biennial herb. In addition, users can learn about the location of vouchered specimens and see images to get a better visual for each plant. ... yellow foxglove Digitalis lanata Grecian foxglove Digitalis lutea straw foxglove Digitalis mariana . By continuing you agree to the use of cookies. Identical to upper epidermis but numerous stomata. It is biennial or perennial herb about 1 metre in height. The combination of heart block with an ectopic dysrhythmia, for example paroxysmal supraventricular tachycardia with block, is particularly suggestive of toxicity due to cardiac glycosides. Belonging to a group of drugs called cardiac glycosides, digitalis is most commonly used to restore adequate circulation in patients with congestive heart failure, particularly as caused by atherosclerosis or hypertension. As the blossom and the leaves of Digitalis are the only natural source of DIG, the anti-DIG antibody does not bind to other known biological materials by now and the detection systems are theoretically highly specific. a = 3β HSD, b = Δ5-3-oxosteroid isomerase, and c = 5βPOR. Digitalis lanata (Grecian Foxglove) is a species of perennial herb in the family Plantaginaceae. Camelot Hybrid (Digitalis purpurea) People affected by these preparations commonly develop related symptoms, such as feelings of discomfort, dizziness, chest discomfort, and ventricular arrhythmias. digitalis lanata Family: Scrophulariaceae | Common name: Woolly Foxglove, Grecian Foxglove This unusual small foxglove produces many compact stems tightly packed with delicately veined and netted, reddish-brown tubular flowers with long pronounced white lips. More than 200 cardiac glycosides are known. In these situations, it is imperative that people seek proper medical attention and discontinue the use of the herbal preparation. This Arabidopsis 5β-POR gene was originally described as a mutant allele negatively affecting cotyledon and leaf vein patterning, therefore called VEP1, required for normal vascular strand development.250 A set of enzymes implicated in the bioconversion of pregnenolone into cardenolides in the model D. lanata included a Δ5-3β-hydroxysteroid dehydrogenase (βHSD) and a Δ5-3-oxosteroid isomerase. Digoxigenin is linked to the C-5 position of uridine nucleotides via a spacer arm containing 11 carbon atoms. An epoxybufenolide series displaying a growth inhibition effect on the cancer cell line KB was described.236 Recently, a series of plant cardiotonic steroids were shown to behave like potent splicing modulators in a test system (a reporter gene construct) designed for screening chemical libraries.237 The steroidal aglycones of these compounds are cardenolides, bearing a lactone ring of five atoms at C17, or bufenolides, bearing a lactone ring of six atoms at C17.2 Digitalis purpurea accumulates high levels of the cardenolides digitoxigenin (76) and digoxigenin (77) and high levels of the cardenolide glycosides (e.g., digoxin (78)) in leaves, with a diversity of sugar residues.238,239 Cardenolide formation has been studied in Digitalis lanata, D. purpurea, and Asclepias incarnata, with an important focus on the activity of pregnane-modifying enzymes.240–243 These steroids are thought to originate from cholesterol or possibly from 24-alkyl-sterols.244 Cardenolide and pregnane biosynthesis requires a 3α-hydroxysteroid-5β-reductase.245 A cDNA encoding a progesterone 5β-reductase (5β-POR) was cloned from Digitalis lanata leaves and functionally expressed in E. coli (Figure 10).246 When progesterone was used as a substrate in this assay, the 5β isomers were formed exclusively. Acute digoxin toxicity often occurs in younger patients and is associated with lower mortality risk. Its corresponding aglycone is known as digoxigenin, and its acetyl derivative as acetyldigoxin. Frequent cardiac adverse effects include heart block and ectopic dysrhythmias (ventricular extra beats, other ventricular tachydysrhythmias, and paroxysmal supraventricular tachycardia). Overlapped resonances of aliphatic carbons at 20–40 ppm are typical of steroids, and the skeleton of lanatoside contains nine methylene groups. Lanatosides can be easily identified by solution 1H and 13C NMR. Elderly patients have higher mortality risk, particularly those with chronic digoxin toxicity and comorbidities such as cardiac and renal diseases. Digitalis. The seeds have the highest concentration of glycoside (4.8%), whereas the leaves, fruit, and milk from the plants contain approximately 0.07%, 0.045%, and 0.036% of glycoside, respectively. Digoxin (Lanoxin) is supplied as tablets in either 125 μg (0.125 mg) or 250 μg (0.25 mg) strengths; as capsules in (solution) 100 μg (0.1 mg) or 200 μg (0.2 mg) strengths; as an elixir of 50 μg/ml (0.05 mg/ml); or for intravenous injection as a sterile solution in 2-ml ampules at 250 μg (0.25 mg) per ml or 100 μg (0.1 mg) per ml.2, Digoxin's mechanisms of action are multifaceted and include positive inotropic effects that are mediated through its inhibition of sodium-potassium adenosine triphosphatase pumps located on myocardial cell membranes, which results in an increase in intracellular sodium concentration. Individual flowers are up to about 1 inch long with a bowl-shaped tube about 1/3 inch long, creamy white with brownish veination, a wide opening at the mouth and a creamy white lower lip that curls down. In the spectral range of carbohydrates (60–90 ppm) appear the signals of three units of digitoxose (one acetylated at C3′ ″) and one glucose. 13C CPMAS NMR spectrum of lanatoside C. Brent Furbee, in Clinical Neurotoxicology, 2009. This may culminate in cardiac arrhythmias and asystole (cardiac arrest). The digitalis consists of dried leaves of Digitalis lanata. And the solid-state NMR? Digitalis is made from the dried leaves of Digitalis purpurea (common foxglove) plants. Figure 10. Flowers grow in the first or second year, depending on the species, and are tubular and bell-shaped, growing to 8 cm in length. (Digitalis lanata) You may have noticed that over the past few years we have really fallen in love with the diversity of the foxglove family. Plagiarism Prevention 4.
