广西蜘蛛抱蛋中一种甾体皂甙定性定量研究

Quality and quantity determination of one steroidal sapogenin of Aspidistra retuda

为了进一步开发和利用广西甾体药源植物奠定基础 ,对广西蜘蛛抱蛋 (Aspidistra retusa K.Y.Langet.S.Z.Huang)块茎甾体皂甙化合物进行了提取分离。在分离得化合物中含量最高的甾体皂甙化合物 4经鉴定为 :偏诺甾体四糖皂甙 ,即 pennogenin-3-β-O-β-D-glucopyranosyl[-α-L-rhamno-pyranosyl(1 -2 ) ]-α-L-rham-no-pyanosyl(1 -4 ) -α-L-rhamnopyranosyl(1 -4 )。该化合物为首次从蜘蛛抱蛋属植物中分离得到。经 HPLC测定其在广西蜘蛛抱蛋中的含量为 1 .5 95 %。

In order to establish the basis of the exploration of the pharamaceutic plants in Guangxi, we isolated the rhizomes of Aspidistra retusa K.Y.Lang et.S.Z.Huang. Among isolated compounds,the chief one of them was identified as pennogenin-3-β-O-β-D-glucopyranosyl[-α-L- rhamnopyranosyl(1-2)]-α-L-rhamnopyanosyl(1-4)-α-L-rhamnopyranosyl(1-4). It had been isolated for the frist time from Aspidistra. Analysed by HPLC,its content was 1.595% in Aspidistra retusa.
