吊扬尘化学成分研究

Studies on Chemical Constituents of Rhizome of Buddleia davidii

目的：对吊扬尘的化学成分进行分离和鉴定。方法：采用硅胶柱色谱、凝胶柱色谱、制备高效液相色谱等方法分离化合物，根据理化性质和波谱解析鉴定各化合物的结构。结果：从吊扬尘石油醚提取物中分离得到8个化合物：Buddlindeterpene B（1）、Buddledin B（2）、Buddledin C（3）、deacetyldihydrobuddledin A（4）、dihydrobuddledin C（5）、Suberosol B（6）、Gadain（7）、Hinokinin（8）。结论：化合物1、4～8为首次从该植物中分离得到。

Objective： To study the chemical constituents of Rhizome of Buddleia davidii. Methods： The chemical constituents were isolated by repeated column chromatography （Toyopearl HW-40C and HPLC） and their structures were elucidated on the basis of physico-chemical properties and spectroscopic features. Results： From the petroleum ether extract of the material, eight compounds were isolated. Their structures were identified as ： Buddlindeterpene B （ 1 ）, Buddledin B （2）, Buddledin C （3）, deacetyldihydrobuddledin A（4）, dihydrobuddledin C（5）, Suberosol B（6）, Gadain （7） and Hinokinin （8）. Conclusion： Compounds 1,4 -8 are isolated from B. davidii for the first time.
