A new steroidal glycoside, agaveside D, isolated from the fruits of Agave cantala was characterized as 3 beta-(alpha-L-rhamnopyranosyl-(1----2),beta-D-glycopyranosyl- (1----3)-beta-D-glucopyranosyl[beta-D-xylopyransoyl-(1----4)-alpha -L-rhamnopyranosyl-(1----2)]-beta-D-glucopyranosyl)-25R-5 alpha-spirostane on the basis of chemical degradation and spectrometry.
从坎他龙舌兰果实中分离出一种新的甾体糖苷——龙舌兰苷D，通过化学降解和光谱分析，其结构被鉴定为3β-(α-L-鼠李糖基-(1→2)，β-D-葡萄糖基-(1→3)-β-D-葡萄糖基[β-D-木糖基-(1→4)-α-L-鼠李糖基-(1→2)]-β-D-葡萄糖基)-25R-5α-螺旋甾烷。
