Four cases of toxic delirium resulting from accidental ingestion of datura seeds are reported. All of them had features of anticholinergic delirium.

Hyoscyamine (atropine) and scopolamine are the predominant tropane alkaloids in the Datura genus, occurring in all plant organs. The assessment of the alkaloid content of various plant parts is essential from the viewpoint of medical use, but also as a potential risk of toxicity for humans and animals. Therefore, a reliable method for the determination of tropane alkaloid content is of high imp...

Influence of different Agrobacterium rhizogenes strains on hairy roots induction and secondary metabolites production in Datura innoxia Mill.

Abstract Background Exploration of biocides in microbial system becomes increasingly interesting. Among the different systems, study endophytes an important field research because their agricultural as well pharmaceutical importance. Bacterial from two medicinal plants North Easter states India had been studied for potential antibacterial and antifungal properties. Results plant species abundan...

BACKGROUND New viruses pathogenic to plants continue to emerge due to mutation, recombination, or reassortment among genomic segments among individual viruses. Tospoviruses cause significant economic damage to a wide range of crops in many parts of the world. The genetic or molecular basis of the continued emergence of new tospoviruses and new hosts is not well understood though it is generally...

A forensic method comprising solid phase extraction and HPLC analysis was developed for the detection and confirmation of atropine and scopolamine, the main toxic alkaloids of Datura stramonium and Datura ferox. This method allowed the direct coupling of an electrospray (ZMD) mass selective detector to the HPLC system. Under these conditions, atropine and scopolamine were well separated from ot...

It has been hypothesized that slow-growing plants are more likely to maximize above-ground biomass and fitness when defoliated by herbivores than those with an already high relative growth rate (RGR). Some populations of the annual herb Datura stramonium L. can tolerate foliar damage better than others. The physiological basis of this difference is examined here in a comparative study of two ec...

Using haploid and diploid Datura innoxia Mill, callus cultures and cell suspensions it was shown that meristematic material usually attains the lowest possible C-value of a given ploidy level. Parenchyma material of callus cultures, however, indicates a broad scattering of C-values up to 16 C, which is paralleled by C-value distribution of the free cell fraction in actively dividing cell suspen...

India has a great wealth of various naturally occurring plant drugs which have potential pharmacological activities. The troublesome weed, Datura stramonium (Jimsonweed) is a plant with both poisonous and medicinal properties and has been proven to have great pharmacological potential with a great utility and usage in folklore medicine. The present investigation was therefore undertaken to dete...
