[摘要] 通过色谱方法从羽叶丁香的茎皮中分到11个化学成分,经质谱、核磁共振谱及与文献数据相比鉴定其结构。其中化合物1为新木脂素,命名为反式羽叶丁香素A (Zpinnatifolin A),10个已知物分别鉴定为pinnatifolin A (2),乙基松柏苷ethylconiferin (3),甲基松柏苷(4),丁香素(5),β, 3, 4trihydroxyphenethyl alcohol(6),(S)(+)2(3, 4dihydroxyphenyl)2ethoxyleth anol(7), 3,4dihydroxyβmethoxyphenethyl alcohol(8), 3, 4, 5三羟基苯乙醇(9),红景天苷(10),羟基酪醇(11),其中3,4,8~11为丁香属内首次报道,5~7为该种首次报道。化合物1对神经小胶质细胞BV2的NO生成显示一定的抑制活性。该研究为表征山沉香抗心肌缺血的药效物质提供了一定的参考。

[Abstract] One new lignan, named Zpinnatifolin A, along with ten known analogues, were isolated from the stem bark of Syringa pinnatifolia by various chromatographic methods. Their structures were extensively determined on basis of MS and NMR spectroscopic data analyses, and comparison with those in literature. Among them, compounds 3,4, and 811 were isolated from this genus for the first time, and 57 were isolated from the specie for the first time. Compound 1 showed a moderate inhibition on NO production in BV2 cells. The present study provides a preliminary data for clarification of bioactive ingredients of S.pinnatifolia with antimyocardial ischemic effect.
