淡黄香茶菜根茎化学成分研究

Study on Chemical Constituents from Rhizome of Rabdosia flavida

目的：研究淡黄香茶菜Rabdosia flavida（Hand.-Mazz.）Hara根茎的化学成分。方法：采用多种柱色谱法进行化学成分分离与纯化,通过现代波谱分析及理化性质等手段对分离得到的化合物进行结构解析。结果：从淡黄香茶菜根茎70%丙酮提取物的乙酸乙酯部位分离得到10个化合物,分别鉴定为：弥罗松酚（1）、脱氢木香内酯（2）、蒲公英甾醇（3）、油酸（4）、乌苏酸（5）、松柏醛（6）、齐墩果酸（7）、6,12,15-三羟基-5,8,11,13-松香四烯-7-酮（8）、5α,8α-环二氧麦角甾-6,22-二烯-3β-醇（9）、胡萝卜苷（10）。结论：化合物1~10均为首次从淡黄香茶菜中分离得到。

Objective： To study the chemical constituents from the rhizome of Rabdosia flavida.Methods： The compounds were isolated and purified by various chromatographic methods,and their structures were elucidated on the basis of spectral data and physicochemical properties.Results： Ten compounds were obtained from ethyl acetate fraction of the 70% acetone extract of Rabdosia flavida rhizome and identified as ferruginol（ 1）,dehydrocostuslactone（ 2）,taraxasterol（ 3）,oleic acid（ 4）,ursolic cid（ 5）,coniferyl aldehyde（ 6）,oleanolic acid（ 7）,6,12,15-trihydroxy-5,8,11,13-abietetra-7-one（ 8）,5α,8α-epidioxyergosta-6,22-dien-3β-ol（ 9）,and daucosterol（ 10）.Conclusion： All the compounds are isolated from Rabdosia flavida for the first time.
