从棘五加叶片中分离到3个新的3 α -羟基齐墩烷型三萜低聚糖基酯，分别为棘苷C1、C4和C5。结构确定为3 α，29-二羟基齐奥烯-12-烯-28-oic酸、3 α，29-二羟基齐奥烯-23-氧齐奥烯-12-烯-28-oic酸、3 α，23,29-三羟基齐奥烯-12-烯-28-oic酸的28-0- α - l-鼠李糖吡喃(1- > - 4)- β -d -葡萄糖吡喃(1- > - 6)- β -d -葡萄糖吡喃酯。
Three novel 3 alpha-hydroxy-oleanane-type triterpene oligoglycosyl esters, spinoside C1, C4 and C5, were isolated from the leaves of Acanthopanax spinosus. The structures were established to be 28-0-alpha-L-rhamnopyranosyl(l-->4)-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl esters of 3 alpha,29-dihydroxy-olean-12-ene-28-oic acid,3 alpha,29-dihydroxy-23-oxo-olean-12-ene-28-oic acid and 3 alpha,23,29-trihydroxy-olean-12-ene-28-oic acid.
