试图调查 Vitex negundo 的化学成分。方法混合物被不同色析法的方法孤立,他们的结构根据 NMR 光谱学被阐明。结果四混合物作为 2 被孤立并且识别, 3, 24-trihydroxyurs-12, 20 (30 )-dien-28-oic acid-28-O -- D-glucopyranosyl 酉旨(1 ) , corosolic 酸(2 ) , vulgarsaponin A (3 ) 并且 2, 3, 24-trihydroxyurs-12-en-28-oic acid-28-O -- Dglucopyranosyl 酉旨(4 ) 分别地。结论化合物 1 是新 triterpenoid glycoside。
AIM: To investigate the chemical constituents of Fitex negundo. METHOD: Compounds were isolated by different chromatographic methods and their structures were elucidated on the basis of NMR spectroscopy. RESULTS: Four compounds were isolated and identified as 2a, 3a, 24-trihydroxyurs-12, 20(30)-dien-28-oic acid-28-O- β-D-glucopyranosyl ester (1), corosolic acid (2), vulgarsaponin A (3) and 2a, 3a, 24-trihydroxyurs-12-en-28-oic acid-28-O-β-D- glucopyranosyl ester (4), respectively. CONCLUSION: Compound I is a new triterpenoid glycoside.
