摘要: 从合欢皮的乙醇提取物中用色谱法分离得到1 个三糖链三萜皂甙1, 21 位侧链含有较为少见的木糖。经化学和波谱分析,将皂甙1 的结构鉴定为3-O-[β-D-吡喃木糖基-(1→2)-β-D-吡喃呋糖基-(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-[4-O-(6R)-2-反式-2,6-二甲基-6-O-β-D-吡喃木糖基)-2,7-辛二烯酰基]-β-D-吡喃鸡纳糖基]-2,7-辛二烯酰基}-金合欢酸-28-O-β-D-吡喃葡萄糖基-(1→3)-[α-L-呋喃阿拉伯糖基-(1→4)]-α-L-吡喃鼠李糖基-(1→2)-β-D-吡喃葡萄糖基酯,为一新化合物,命名为合欢皂甙J23(1)
