目的 研究瓦山安息香Styrax perkinsiae树皮的化学成分.方法 采用硅胶柱色谱、大孔吸附树脂等方法进行分离纯化,根据波谱数据并参考文献鉴定其化学成分.结果 从瓦山安息香树皮正丁醇部位分离得到10个木脂素类化合物,分别鉴定为obassioside B(1)、落叶松脂醇-4-O-β-D-葡萄糖苷(2)、(-)-开环异落叶松脂素-4-O-β-D-吡喃葡萄糖苷(3)、落叶松脂醇-4'-O-β-D-葡萄糖苷(4)、lanicepside A(5)、异落叶松脂素-4-O-β-D-吡喃葡萄糖苷(6)、(+)-落叶松醇-9-β-D-吡喃葡萄糖苷(7)、isotachioside(8)、2R^*,3S^*-dihydrodehydrodiconiferyl alcohol 4'-O-β-D-glucopyranoside(9)、松脂醇(10).结论 化合物2～9为首次从安息香属植物中分离的得到.

Objective To study the chemical constituents from the stem bark of S. perkinsiae. Methods The chemical constituents were separated and purified by chromatographic methods after solvent extraction and were identified by spectroscopic analyses. Results Ten lignans were isolated from the stem bark of S. perkinsiae and identified as following: obassioside B (1), lariciresinol 4-O-β-D-glucoside (2), (-)-secoisolariciresinol 4-O-β-D-glucopyranoside (3), lariciresinol 4'-O-β-D-glucoside (4), lanicepside A (5), isolariciresinol 4-O-β-D-glucopyranoside (6), (+)-lariciresinol 9-O-β-D-glucopyranoside (7), isotachioside (8), 2R^*,3S^*-dihydro- dehydrodiconiferyl alcohol 4'-O-β-D-glucopyranoside (9), and pinoresinol (10). Conclusion Eight compounds (2—9) are isolated from the plants of Styrax Linn. for the first time.
