ABSTRACT

Objective: To study the chemical constituents in the leaves of Datura metel. Methods: The chemical constituents of ethanol extract from the leaves of D. metel were isolated and purified by chromatography over silica gel, AB-8 macroperous resin, ODS, Sephadex LH-20 columns, and RP-preparative HPLC. The structures were elucidated on the basis of physicochemical properties and spectral data analyses. Results: Forteen compounds were isolated and identified as naphthisoxazol A (1), congmuyaglyeoside I (2), L-tryptophan (3), quercetin3-O-2-(E-caffeoyl)-α-larabinopyranosyl- (1→2)-β-D-glucopyranoside-7-O-β-D-glucoside (4), n-butyl-O-α-D-fructofuranosidase (5), anoectochine (6), dihydrovomifoliol-O-β-D-glucoside (7), (6S, 7E, 9S)-9- [(β-D-glucopyranosyl)-oxy] megastigma-4, 7-dien-3-one (8), kaepmferol-3, 7-di-O-β-D-glucopyranoside (9), kaempferol-7-O-β-D-glucoside (10), quercetin-7-O-glucoside (11), (6S, 9R)-6-hydroxy-3-ketone-α-violet-grape alcohol-9-O-β-D-glucopyranoside (12), stigmasterol (13), and stigmasterol-3-O-β-D-glucoside (14). Conclusion: Compounds 1-8 are firstly found in the plants of Solanaceae.
