Abstract

A triterpenoid saponin (1) was obtained from the stem barks of Albizia julibrissin Durazz. Its structure was elucidated as 3-O-[beta-D-xylopyranosyl-(1 --> 2)-alpha-L-arabinopyranosyl-(1 --> 6)-beta-D-glucopyranosyl]-21-O-[(6S)-2-trans-2-hydroxymethyl-6-methyl-6-O-beta-D-quinovopyranosyl-2, 7-octadienoyl]-16-deoxy-acacic acid 28-O-beta-D-glucopyranosyl-(1 --> 3)-[alpha-L-arabinofuranosyl-(1 --> 4)]-alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-glucopyranosyl ester (1), named as Julibroside J26, based on the chemical and spectral methods.

摘要

从合欢（Albizia julibrissin Durazz.）的茎皮中获得了一种三萜皂苷（1）。通过化学和光谱方法，其结构被鉴定为3-O-[β-D-吡喃木糖基-(1→2)-α-L-吡喃阿拉伯糖基-(1→6)-β-D-吡喃葡萄糖基]-21-O-[(6S)-2-反式-2-羟甲基-6-甲基-6-O-β-D-奎诺吡喃糖基-2,7-辛二烯酰]-16-脱氧金合欢酸28-O-β-D-吡喃葡萄糖基-(1→3)-[α-L-阿拉伯呋喃糖基-(1→4)]-α-L-鼠李吡喃糖基-(1→2)-β-D-吡喃葡萄糖基酯（1），命名为朱利布罗苷J26。
