From the water-soluble fraction of a methanol extract of leaves of Alangiumpremnifolium, two new megastigmaneglycosides, alangionosides N and O, along with three known megastigmaneglycosides, dendranthemoside A and alangionosides A and B, were isolated. Shimaurinosides A and B, xylopyranosyl(1-->6)glucopyranosides of simplealcohols were also found to be constituents of the water-soluble fraction
从 Alangium premnifolium 叶子的甲醇提取物的水溶性部分中,分离出两种新的 megastigmane 苷、alangionosides N 和 O,以及三种已知的 megastigmane 苷、dendranthemoside A 和 alangionosides A 和 B。Shimaurinosides A 和 B,简单醇的吡喃木糖苷 (1-->6) 吡喃葡萄糖苷也被发现是水溶性部分的成分。通过光谱分析确定结构。
