ABSTRACT
Objective: To investigate the chemical constituents from Vitex negundo. Methods: The chemical constituents were separated and purified by column chromatography including ODS, Sephadex LH-20, and silica gel columns. Their structures were elucidated on the basis of physicochemical properties and spectral data. Results: Eleven compounds were identified as isoorientin (1), vitegnoside (2), luteolin-7-O-β-D-glucopyranoside (3), isovitexin (4), luetolin-3'-O-β-D-glucuronide (5), apigenin-7-O-β-D-glucoside (6), kaempferol-3-O-β-D-glucopyranoside (7), methyl rosmarinate (8), 5-O-caffeoyl quinic acid methylester (9), caffeic acid (10), and grevilloside G (11), respectively. Conclusion: Compounds 3 and 4 are isolated from V. negundo for the first time, and compounds 5-11 are firstly obtained from the plants of Vitex Linn.
ABSTRACT
Object To determine the amount of acacetin-7-O-β-D-glucoside and apigenin-7-O-β-D-glucoside in Chrysanthemum morifolium Ramat. from different localities. Methods By the use of HPLC. Results The contents of acacetin-7-O-β-D-glucoside in Boju1, Chuju2, Gongju3 and Hangju4 were 0.082 6%～0.124 9%, 0.015 7% and 0.033 5% respectively; the contents of apigenin-7-O-β-D-glucoside in Chuju, Boju, Gongju and Hangju were 0.012 6%, 0.027 4%, 0.117 7% and 0.587 7% respectively. Conclusion The contents of the two flavone glycoside in C. morifolium from different localities were markedly different.
