唐古特铁线莲化学成分研究

Chemical Constituents of Clematis tangutica

利用硅胶、Sephadex LH-20、ODS、MPLC柱色谱等方法对唐古特铁线莲的化学成分进行分离纯化,根据理化性质及波谱数据鉴定化合物的结构。从唐古特铁线莲乙酸乙酯萃取部位分离鉴定了11个化合物,分别鉴定为木犀草素(1),Clemaphenol A(2),α-亚麻酸(3),胡萝卜苷(4),胡萝卜苷苷元(5),常春藤-3-O-α-L-鼠李糖(1→4)-β-D-葡萄糖(6),常春藤-3-O-α-L-阿拉伯糖(1→3)-α-L-鼠李糖(1→4)-β-D-葡萄糖(7),Acanjaposide G(8),常春藤配基(9),芹菜素(10),灯台酸(11)。所有化合物均为首次从唐古特铁线莲中分离得到。

The chemical constituents of Clematis tangutica was investigated by the methods of Si-gel, Sephadex LH-20, ODS and MPLC, and the structures of compounds were identified by means of physicochemical properties and spectral analysis. Eleven compounds were isolated from the ethyl acetate fraction of Clematis tangutica, and identified as luteolin （ 1 ）, clemaphenol A （2）, alpha-linolenic acid （3）, daucosterol （4）, daucosterolaglycone （5）, hederagenin-3 -O-α-L-rham- nopyranosyl （1→4） -β-D-glucopyranosyl （6）, hederagenin-3-O-α-L-arabinopyranosyl （ 1→3 ） -α-L-rhamnopyranosyl （ 1 4） -β-D-glucopyranosyl（7）, Acanjaposide G （8）, hederagenin （9）, apigenin （10）, echitin （11）. All of these compounds were obtained from the plant for the first time.
