从枳椇( acerba Lindl.)叶中分得两个达玛烷型三萜皂甙并分别鉴定为:枳椇皂甙C_2(hovenia saponin C_2,V),酸枣仁皂甙元-3-O-[α-L-吡喃鼠李糖(1→2)][β-D-吡喃半乳糖(1→2)-β-D-吡喃葡萄糖(1→3)]-α-L-吡喃阿拉伯糖甙(jujubogenin-3-O-[α-L-rhamnopyranosyl(1→2)][β-D-galactopyranosyl(1→2)-β-D-glucopyranosyl(1→3)]-α-L-arabinopyranoside,Ⅶ),其中Ⅴ系首次从该植物中分得,Ⅷ是新化合物,命名为枳犋皂甙A_1(hovacerboside A_1)。 Two dammarane-type triterpene saponins were isolated from acerba Lindl. Leaves and identified as follows: saponin C 2 (V), Suanzaorin 3-O-[α- L-rheophamrhamnose (1→2)][β-D-galactopyranose (1→2)-β-D-glucopyranose (1→3)]-α-L-pyrantoaramose甙(jujubogenin-3-O-[α-L-rhamnopyranosyl(1→2)][β-D-galactopyranosyl(1→2)-β-D-glucopyranosyl(1→3)]-α-L-arabinopyranoside, VII), in which V is obtained from the plant for the first time, and VIII is a new compound named as Hovacerboside A_1.
