Phenols from the stem of Machilus ichangensis Rehd. et Wils.
摘要
Abstract
To study phenols in the stem of Machilus ichangensis Rend, et Wils. , The obtained compounds were isolated by different chromatographic methods and their structures were identified by modern spectral technology (MS, 'H NMR, 13C NMR, DEPT and CD) and physicochemical properties. Sixteen compounds were isolated from the 95% ethanol extract of Machilus ichangensis , They were identified as (2R, 3R)-4'-hy-droxy-5,7, 3'-trimethoxyflavan-3-ol (1), (2R, 3R)-3-hydroxy-5 , 7-dimethoxy-3', 4'-methylenedioxy-flavan (2), ( + )-catechin (3), ( — )-epicatechin (4), naringenin (5), davidigenin (6), E-/?-coumaric acid (7), caffeic acid (8), ferulic acid (9), isoerulic acid (10), scopoletin (11), isoscopoletin (12), piperonylic acid (13), vanillic acid (14), protocatechuic acid (15), syringic acid (16). All compounds were isolated from this plant for the first time.关键词
