datura discolor/breast neoplasms

Background: Cancer is a horrific disease relentlessly affecting human population round the globe. Genus Datura encompasses numerous species with reported medicinal uses. However, its potential as a source of natural anticancer agents is

A new withanolide, dinoxin B (12,21-dihydroxy-1-oxowitha-2,5,24-trienolide-27-O-β-D-glucopyranoside, 1), was isolated from a methanol extract of Datura inoxia leaves, using bioassay-guided fractionation. The structure was determined by spectroscopic techniques, including (1)H, (13)C, and 2D NMR

Thirteen new withanolide aglycones, baimantuoluolines L-X (1-13) and one new withanolide glycoside, baimantuoluoside J (14) were isolated from Datura metel L. flowers. The structures of the new compounds were elucidated by the detailed analysis of 1D and 2D NMR techniques and mass spectrometry,

Four new indole alkaloids, daturametelindoles A-D (1-4) were isolated from the EtOAc soluble partition of the ethanol extract of the Datura metel seeds. The structures of the new compounds were determined based on spectroscopic evidence, including their 1D- and 2D-NMR spectra and mass spectrometry.
