Chemical investigation of the 50% ethanol eluate fraction from a macroporous resin of flowers of Datura metel L. collected in the Jiangsu Province of China resulted in the isolation of two new withanolides, baimantuoluoline G (1) and baimantuoluoside H (2). Their structures were elucidated as (12β,6β,22R)-1,10-seco-6,12,27-trihydroxy-26-oxo-witha-3,5,24-trienolide-1-oic acid-ε-lactone (1) and (...
The present study was designed to evaluate relative contribution of different polyphenols (total phenolics, flavonoids, flavonols) and their antioxidants activities in aqueous extracts of different parts of some plants; Argemone mexicana, Datura metel, Calotropis procera, Thevetia peruviana, and Cannabis sativa. The antioxidants (total phenolics, flavonoids, flavones) were determined by chemica...
Four new withanolides named dmetelins A-D (compounds 1-4), along with the known compound 7α,27-dihydroxy-1-oxo-witha-2,5,24-trienolide (5) were isolated from the leaves of Datura metel L. (Solanaceae). Their structures were elucidated on the basis of detailed analysis of 1D and 2D NMR and mass spectrometry data. All the compounds were evaluated for their inhibitory effects on lipopolysaccharide...
In the early morning hours of July 9, 2008, six adult family members were admitted to a hospital emergency department in Maryland with hallucinations, confusion, mydriasis, and tachycardia of approximately 3-4 hours duration. Approximately 4-5 hours earlier, all six family members had shared a meal of homemade stew and bread. Subsequent investigation by the Montgomery County Department of Healt...
plants are the important sources of drugs. secondary metabolites are responsible for therapeutic propertiesin plants. three compounds including (-)-hyoscyamine, its racemate atropine, and scopolamine (hyoscine) are the most famous tropane alkaloids in the solanaceae familly. nowadays, attempts to developthese alkaloids in biotechnological procedures which are principally based on the hairy root...
