摘要
采用正相硅胶、Sephadex LH-20、ODS、HPLC等色谱手段,对中药白术的化学成分进行研究,从白术干燥根茎95%乙醇提取物中分离得到3个倍半萜类化合物,并根据波谱数据和理化性质对其结构进行鉴定,分别鉴定为2个桉叶烷倍半萜(7Z)-8β,13-diacetoxy-eudesma-4(15),7(11)-diene(1)、7-oxo-7,8-secoeudesma-4(15),11-dien-8-oic acid(2)及1个愈创木烷倍半萜guai-10(14)-en-11-ol(3)。其中化合物1和2为新化合物,化合物3为首次从菊科中分离得到。化合物1~3对SREBPs均具有一定的抑制作用。
Three sesquiterpenoids were isolated and purified from the 95%ethanol extract of Atractylodis Macrocephalae Rhizoma by column chromatography on silica gel,Sephadex LH-20,ODS,and high-performance liquid chromatography(HPLC).Their chemical structures were identified on the basis of spectroscopic analysis and physiochemical properties as(7Z)-8β,13-diacetoxy-eudesma-4(15),7(11)-diene(1),7-oxo-7,8-secoeudesma-4(15),11-dien-8-oic acid(2),and guai-10(14)-en-11-ol(3).Compounds 1 and 2 are new compounds and compound 3 was obtained from Compositae family for the first time.Compounds 1,2,and 3 showed weak inhibitory activities against sterol regulatory element-binding proteins(SREBPs).
