降香中黄酮类化学成分研究(Ⅱ)

Studies on the Flavonoids from Lignum Dalbergiae Odoriferae(Ⅱ)

目的:对降香的化学成分进行研究。方法:采用反复硅胶柱色谱、葡聚糖凝胶色谱等分离纯化,通过理化常数和波谱分析鉴定其化学结构。结果:从降香中分离得到9个黄酮类化合物,分别鉴定为:黄颜木素(1)、木犀草素(2)、染料木素(3)、异半皮桉苷(4)、木犀草素-6-C-葡萄糖苷(5)、高北美圣草素(6)、甘草素(7)、大豆素(8)、柚皮素(9)。结论:化合物1、4、5、6为首次从该植物中分离得到。

Objective：To study the chemical constituents of Lignum Dalbergiae Odoriferae.Methods：The isolation and purification were carried out by repeated silica gel column chromatography,and the chemical structures were determined by physico-chemical properties and spectral analysis.Results：Nine compounds were isolated and identified as fisetin（1）,luteolin（2）,genistein（3）,isohemiphloin（4）,6-C-glycopyranosyl luteolin（5）,homoeriodictyol（6）,liquiritigenin（7）,daidzein（8） and naringenin（9）.Conclusion：Compounds 1,4,5,6 are isolated from this plant for the first time.
