目的研究藤香树Schisandrapropinquavar.intermedia的化学成分。方法应用多种色谱技术进行分离纯化,根据化合物的理化常数测定和光谱数据分析鉴定其结构。结果得到9个化合物,分别鉴定为香草酸-4-O-β-D-阿洛糖苷(Ⅰ)、红景天苷(Ⅱ)、2-hydroxy-5-(2-hydroxyethyl)-phenyl-β-D-glucopyranoside(Ⅲ)、3,4-dimethoxyphenyl-4-β-D-glucopyranoside(Ⅳ)、3,5-二羟基苯甲酸-4-O-β-D-葡萄吡喃糖苷(Ⅴ)、3,5-二甲氧基-4-羟基苯甲酸(Ⅵ)、对甲氧基苯甲酸(Ⅶ)、香草酸(Ⅷ)和原儿茶酸(Ⅸ)。结论化合物Ⅰ为新的酚苷化合物,命名为藤香酚苷(intermedoside),其余均为首次从藤香树中获得。

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-β-D-allopyranoside (Ⅰ), salidroside (Ⅱ), 2-hydroxy-5-(2-hydroxyethyl)-phenyl-β-D-glucopyranoside (Ⅲ), 3, 4-dimethoxyphenyl-4-β-D-glucopyranoside (Ⅳ), 3, 5-dihydroxybenzoic acid-4-O-β-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.
