Protabase Record Display Datura Stramonium L
Protabase Record display www.prota.org Datura stramonium L. Protologue Sp. pl. 1: 179 (1753). Family Solanaceae Chromosome number 2n = 24 Vernacular names Thorn apple, green thorn apple, Jimson weed, Jamestown weed, devil’s apple, devil’s trumpet, stramonium (En). Pomme épineuse, stramoine, datura, feuille du diable, herbe du diable (Fr). Figueira do inferno, pomo espinhoso, erva dos bruxos, palha verde, estramonio (Po). Muranha (Sw). Origin and geographic distribution Datura stramonium is native to the Americas and has been introduced in many tropical, subtropical and even temperate regions. It is a naturalized weed in many African countries, but is probably seriously under-reported. Uses Datura stramonium and Datura metel L. have largely similar medicinal uses throughout the world. The most widely known use of Datura stramonium and of other Datura species is for relieving asthma, cough, tuberculosis and bronchitis by smoking the dried leaves, roots or flowers. ‘Asthma cigarettes’ have been shown to be very effective in some cases, but in other cases they had little or no effect. Cigarettes made with the leaves are also used to treat Parkinson’s disease. A decoction or infusion of leaves is given as a sedative to mental and schizophrenic patients. The leaves are applied as a dressing to cure rheumatic pain, swellings, wounds, gout, burns, ingrown toe-nails, fungal infections, tumours and ulcers. Dried pulverized leaves are dusted on wounds or applied after mixing the powder with fat or Vaseline. In DR Congo pounded fresh root and fresh leaves are soaked in water and the liquid is given in enema as an abortifacient. -
Ergot Alkaloids Mycotoxins in Cereals and Cereal-Derived Food Products: Characteristics, Toxicity, Prevalence, and Control Strategies
agronomy Review Ergot Alkaloids Mycotoxins in Cereals and Cereal-Derived Food Products: Characteristics, Toxicity, Prevalence, and Control Strategies Sofia Agriopoulou Department of Food Science and Technology, University of the Peloponnese, Antikalamos, 24100 Kalamata, Greece; [email protected]; Tel.: +30-27210-45271 Abstract: Ergot alkaloids (EAs) are a group of mycotoxins that are mainly produced from the plant pathogen Claviceps. Claviceps purpurea is one of the most important species, being a major producer of EAs that infect more than 400 species of monocotyledonous plants. Rye, barley, wheat, millet, oats, and triticale are the main crops affected by EAs, with rye having the highest rates of fungal infection. The 12 major EAs are ergometrine (Em), ergotamine (Et), ergocristine (Ecr), ergokryptine (Ekr), ergosine (Es), and ergocornine (Eco) and their epimers ergotaminine (Etn), egometrinine (Emn), egocristinine (Ecrn), ergokryptinine (Ekrn), ergocroninine (Econ), and ergosinine (Esn). Given that many food products are based on cereals (such as bread, pasta, cookies, baby food, and confectionery), the surveillance of these toxic substances is imperative. Although acute mycotoxicosis by EAs is rare, EAs remain a source of concern for human and animal health as food contamination by EAs has recently increased. Environmental conditions, such as low temperatures and humid weather before and during flowering, influence contamination agricultural products by EAs, contributing to the Citation: Agriopoulou, S. Ergot Alkaloids Mycotoxins in Cereals and appearance of outbreak after the consumption of contaminated products. The present work aims to Cereal-Derived Food Products: present the recent advances in the occurrence of EAs in some food products with emphasis mainly Characteristics, Toxicity, Prevalence, on grains and grain-based products, as well as their toxicity and control strategies. -
Picrotoxin-Like Channel Blockers of GABAA Receptors

Musah Department of Chemistry, State University of New York at Albany, 1400 Washington Ave, Albany, NY, 12222, USA ARTICLE INFO ABSTRACT Keywords: Plants that produce atropine and scopolamine fall under several genera within the nightshade family. Both Hierarchical classification atropine and scopolamine are used clinically, but they are also important in a forensics context because they are Psychoactive plants abused recreationally for their psychoactive properties. The accurate species attribution of these plants, which Seed species identifiction are related taxonomically, and which all contain the same characteristic biomarkers, is a challenging problem in Metabolome profiling both forensics and horticulture, as the plants are not only mind-altering, but are also important in landscaping as Direct analysis in real time-mass spectrometry ornamentals. Ambient ionization mass spectrometry in combination with a hierarchical classification workflow Chemometrics is shown to enable species identification of these plants. The hierarchical classification simplifies the classifi- cation problem to primarily consider the subset of models that account for the hierarchy taxonomy, instead of having it be based on discrimination between species using a single flat classification model. Accordingly, the seeds of 24 nightshade plant species spanning 5 genera (i.e. Atropa, Brugmansia, Datura, Hyocyamus and Mandragora), were analyzed by direct analysis in real time-high resolution mass spectrometry (DART-HRMS) with minimal sample preparation required. -

Since they are natural, plants are wrongly considered nondangerous; therefore people used them in various contexts. Each plant is used alone or in mixture with others, where knowledge and the requirements of preparation and consumption are not mastered. Tus, intoxications due to the use of plants have become more and more frequent. Te reports of intoxications made at the Antipoison Center and Pharmacovigilance of Morocco (ACPM) support this fnding, since the interrogations sufered by the victimsshowthattheuseofplantsispracticedirrationally,anarchically, and uncontrollably. Faced by the increase of these cases of poisoning in Morocco, it seemed necessary to investigate the nature of poisonous plants, their monographs, and the chemicals responsible for this toxicity. 1.

Studies in Microencapsula Tion of Rodenticides
STUDIES IN MICROENCAPSULA TION OF RODENTICIDES P. B. CORNWEL,.L, Director of Research, Rentokil Laboratories ltd., Felcourt, E. Grinstead, Sussex, England ABSTRACT: Warfarln, zinc phosphide, norbormlde and alphachloralose have been mlcroencapsu lated by the technique of coacervatlon and fed to laboratory rats (R. norveglcus) and mice (H. mU$CUlus). Results are given of experiments In which the concentration of rodentlclde, wall material and phase ratio have been varied separately and in combination. Experiments are also repot'ted In which normal and encapsulated rodentlclde have been fed together In the same test diet. Hlcroencapsulatlon can Increase the Intake of rodentlcldes, appreciably, whether or not alternative food is simultaneously available. Nevertheless, significantly higher kills from higher Intakes of poison have not been achieved, Indicating difficulties In optimising the characteristics of the capsule wall to achieve the desired release of Ingested active In gredient. INTl\ODUCTION Hlcroencapsulatlon can be defined as a chemical process by which minute amounts of solids or liquids are enclosed within a thin wall of suitable material to prevent their reaction with some component of the environment. The properties of the wall are so designed to keep the reactive materials apart until they are required to mix. Hlcroencapsulatlon, as an Industrial process, has been developed for many applications by the Natlon~l Cash Register Co. These Include carbonless copying paper, drugs with design ed release characteristics, as well as uses In the perfumery, adhesive and food Industries (Gordon, 1965) . The costs vary from 40 U.S. cents to $4 per kg. of encapsulated material (Watson, 1970) and many future applications have been proposed. -

Received: 21 September 2020; Accepted: 20 October 2020; Published: 23 October 2020 Abstract: Ayahuasca is a hallucinogenic botanical beverage originally used by indigenous Amazonian tribes in religious ceremonies and therapeutic practices. While ethnobotanical surveys still indicate its spiritual and medicinal uses, consumption of ayahuasca has been progressively related with a recreational purpose, particularly in Western societies. The ayahuasca aqueous concoction is typically prepared from the leaves of the N,N-dimethyltryptamine (DMT)-containing Psychotria viridis, and the stem and bark of Banisteriopsis caapi, the plant source of harmala alkaloids.
