对密脉鹅掌柴进行了化学成分研究.采用硅胶柱色谱、RP-C8柱色谱等方法分离化学成分,1HNMR,13C NMR等方法进行结构鉴定,从中分离鉴定了4个化合物:14-羟甲基-3-氧-β-D-吡喃葡萄糖醛酸基(1→2)-β-D-吡喃鼠李糖基齐墩果酸苷(1),绿原酸(2),异绿原酸C(3),莱蓟素(4).化合物1为新化合物,化合物2~4均为首次从该植物中分离得到. The chemical constituents of Artemisia frigida were studied.The constituents were isolated by silica gel column chromatography and RP-C8 column chromatography, and the chemical structures were identified by 1HNMR and 13C NMR. Four compounds were identified: 14-hydroxymethyl (1 → 2) -β-D-rhamnopyranosyl-oleanolic acid (1), chlorogenic acid (2), iso-green C (3) and silymarin (4) .Compound 1 was a new compound, and compounds 2 ~ 4 were isolated from this plant for the first time.
