摘要
目的:对藏药高原天名精Carpesium lipskyi甲醇提取物化学成分进行分离鉴定。方法:利用普通硅胶柱色谱方法进行分离、纯化,并经超导核磁共振(NMR)、质谱(MS)、红外(IR)等现代波谱技术确定其结构。结果:从高原天名精的甲醇室温提取物乙酸乙酯部位获得6个化合物,其结构被确定为β-谷甾醇(I),豆甾醇(II),二十二烷醇(III),胡萝卜苷(IV),5-羟基-3,6,7,4’-四甲氧基黄酮(V),异鼠李素-3-O-β-D-葡萄糖苷(VI)。结论:6个化合物均为首次从该植物中分离得到。
Objective:To isolate and identify the chemical constituents from Carpesium lipskyi,which was used as traditonal herb medicine in the treatment of some diseases.Method: These compounds were isolated by column chromatography and their structures were elucidated through spectroscopic analysis(NMR and MS).Result: Seven compounds were isolated and identified as: β-sitosterol(I),stigmasterol(II),1-docosanol(III),daucosteol(IV),5-hydroxy-3,6,7,4 ’-tetramethoxyflavone(V),isorhamnetin-3-O-β-D-glucopyranoside(VI).Conclusion:All these compounds were isolated from Carpesium lipskyi for the first time.
