RESUMO
Objective To study the bioactive components from stems of Schisandra propinqua var. intermedia. Methods Compounds were separated with acombination of multi-chromatography. Their che- mical structures were determined on the basis of spectral analysis and chemical evidence. Results Nine compounds were isolated from S. propinqua var. intermedia. The structures were elucidated as vanillic acid- 4- O-?-D-allopyranoside (Ⅰ), salidroside (Ⅱ), 2-hydroxy-5-(2-hydroxyethyl)-phenyl-?-D-glucopyranoside (Ⅲ), 3, 4-dimethoxyphenyl-4-?-D-glucopyranoside (Ⅳ), 3, 5-dihydroxybenzoic acid-4-O-?-D-glucopyranoside (Ⅴ), 3, 5-dimethoxy-4-hydroxy-benzoic acid (Ⅵ), 4-methoxy-benzoic acid (Ⅶ), vanillic acid (Ⅷ) and protocatechuic acid (Ⅸ). Conclusion Compound Ⅰ is a new phenolic alloside and others are isolated from S. propinqua var. intermedia for the first time.
