Background & Aim: The aim of this study was to investigate the antimicrobial activity of two rangeland-medical plants extracts, Prosopis farcta L. and Datura stramonium L., against Staphylococcus aureus isolated from sheep in Zabol city. Experimental: The P. farcta and D. stramonium were collected from...

The carbohydrate binding specificity of Datura stramonium agglutinin was studied by analyzing the behavior of a variety of complex-type oligosaccharides on a D. Stramonium agglutinin-Sepharose column. Oligosaccharides which contain Gal beta 1----4GlcNAc-beta 1----4(Gal beta 1----GlcNAc beta 1----2)Man units are retarded in the column so long as the pentasaccharide unit is not substituted by oth...

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...

Thirty-six alkaloids were identified in the organs of Datura ceratocaula by GC/MS. Thirty-three of them have not been previously reported for the species. Furthermore, a new tropane ester was tentatively identified as 3-(3'-formyloxytropoyloxy)tropane on basis of its mass spectral fragmentation. Hyoscyamine was the main alkaloid in the plant organs.

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...
