This study was carried out in order to investigate some of the effects of aqueous seed extract of Datura stramonium on the histology of the frontal cortex and hippocampus of Sprague Dawley rats as marker of toxicity. 16 adult male Sprague Dawley rats were used for this study. The rats were distributed into two groups (A and B). The rats in group B served as the treatment group and were administ...

The common five weed species Datura stramonium L., Solanum nigrum L., Brassica kaber (DC), Capsella bursapastoris L. and Malva parviflora L., were tested for their susceptibility to an isolate of TYLCSV from Murcia, Spain (TYLCSV-ES), using the B-, Qand S-biotypes of Bemisia tabaci (Gennadius). Both, Band Q-biotypes were shown to transmit TYLCSV-ES from infected tomato to S. nigrum and D. stram...

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...

Datura stramonium seeds contain at least three chitin-binding isolectins [termed Datura stramonium agglutinin (DSA)] as homo- or heterodimers of A and B subunits. We isolated a cDNA encoding isolectin B (DSA-B) from an immature fruit cDNA library; this contained an open reading frame encoding 279 deduced amino acids, which was confirmed by partial sequencing of the native DSA-B peptide. The seq...

Most widely affecting species include Culex quinquefasciatus, A. albopictus and aegypti which serve as vectors for many hematophagous diseases. Various control measures have been used to the mosquitoes but most important is use of synthetic insecticides. This research focused on botanical extracts green synthesized silver nanoparticles four different plants i.e. Moringa Olifera, Zingiber offici...

A new withanolide, named withawrightolide (1), and four known withanolides (2-5) were isolated from the aerial parts of Datura wrightii. The structure of compound 1 was elucidated through 2D NMR and other spectroscopic techniques. In addition, the structure of withametelin L (2) was confirmed by X-ray crystallographic analysis. Using MTS viability assays, withanolides 1-5 showed antiproliferati...
