Datura is known as a medicinal plant and plant hallucinogen all over the world. Datura has a very special place in Ayurveda since all parts of the plant namely leaves, flowers, seeds, roots, have been used for a wide range of medication such as treatment of leprosy, rabies, insanity, etc. The extract of Datura, however, is a potent poison and its indiscriminate use may lead to delirium and acut...

Three medicinal plants Abutilon mauritianum, Bacopa monnifera and Datura stramonium were assessed for phytochemical components and antimicrobial activity. The results revealed that all the three plant extracts contained saponins, tannins and alkaloids. Only Datura stramonium contained glycosides. The plants exert varying inhibitory effects on Pseudomonas aeruginosa, Klebsiella pneumonia and Esc...

Defensive traits exhibited by plants vary widely across populations. Heritable phenotypic differentiation is likely to be produced by genetic drift and spatially restricted gene flow between populations. However, spatially variable selection exerted by herbivores may also give rise to differences among populations. To explore to what extent these factors promote the among-population differentia...

The antimycotic potential of Datura metel (syn. Datura alba Nees.) was investigated in vitro against Ascochyta rabiei, the cause of chickpea blight disease. The pathogen was exposed to various n-hexane concentrations (1, 2, 3 and 4% w/v) of shoot and root extracts of D. metel using poisoning food technique. All the employed concentrations of both root and shoot extracts significantly suppressed...

Alkaloids, GS-MS, Datura stramonium The alkaloid spectrum in roots, leaves and seeds of Datura stramonium L. was investigated by GC-MS. Twenty-nine tropane alkaloids are detected. Twelve of them are new constituents for the species and the two tropane esters 3-(3'-acetoxytropoyloxy)tropane (21) and 3-(2'-hydroxytropoyloxy)tropane (26) are described for the first time.

Background & Aims: In regard to the importance of atropine and scopolamine as medicines with natural source, this study was aimed to investigate the effect of chloramphenicol as an inhibitor of protein synthesis on the alkaloids content of Datura stramonium. Method: After initial preparation of medicinal garden seeds, they were planted 50 cm apart in four different sections. Three different con...

Two case reports of Datura stramonium intoxications are presented. The first one was a self poisoning, with a moderate anticholinergic syndrome and a spontaneous improvement. The second one was a recreational use of Datura stramonium for its hallucinogenic properties. The anticholinergic syndrome was marked and the improvement required orotracheal intubation, mechanical ventilation, intraveinou...

In the past few decades there has been an exponential growth in the field of herbal medicine to be a better option for their healthcare needs, owing to their natural origin and reduced side effects. Datura spp. is one of the 50 fundamental herbs used in traditional medicine. The dry flower, particularly the violet coloured, if rolled and used like cigar, will help to relive the asthma or wheezi...

Plant resistance to herbivores involves physical and chemical plant traits that prevent or diminish damage by herbivores, and hence may promote coevolutionary arm-races between interacting species. Although Datura stramonium's concentration of tropane alkaloids is under selection by leaf beetles, it is not known whether chemical defense reduces seed predation by the specialist weevil, Trichobar...
