摘　　要：自猫儿瓜（DecaisneafargesiiFranch）根中分离出10种单体化合物。本文报道其中3种化合物的结构鉴定，经化学方法和光谱解析鉴定为本通皂甙PG（Ⅰ），川续断皂甙B（Ⅱ），木通皂甙PK（Ⅲ），Ⅰ、Ⅱ和Ⅲ均为首次从植物中获得。Tree compounds were isolated from the Chinese medicinal plant (Decaisnea fargesii). Their structures were established by means of chemical and spetroscopic evidence as follows: 3-O-β-D-xylopyranosyl (1 → 3 )-α-L-rhamnopyranosyl (1 → 2 )-α-L-arabinopyranosyl hederagenin ; 3-O-β-D-α-L-rhamnopyranosy (1→ 2 )-α-L-arabinopyranosyl hederagenin 28-O-α-L-rhamnopyranosyl (1→4 ) -β-D-glucopyranosyl (1→6 )-β-D-glucopyranoside; 3-O-α-L-rhamnopyranosyl (1→2 ) -α-L-arabinopyranosyl hederagenin 28-O-α-LLrhamnopyranosyl (1 →4 ) -β-D-glucopyranosyl (1 → 6 ) -β-D-glucopyranoside.
