摘要： 从合欢皮95%乙醇提取物中分得2个新三糖链九糖皂甙(1,2),经化学方法和光谱分析,将其结构分别鉴定为:3-O-[β-D-吡喃木糖基-(1→2)-β-D-吡喃阿拉伯糖基-(1→6)-β-D-葡萄糖基]-21-O-(6S)-2-反式-2,6-二甲基-6-O-[4-O-((6R)-2-反式-2,6-二甲基-6-O-β-D-吡喃鸡纳糖基-2,7-辛二烯酸基)-β-D-吡喃鸡纳糖基]-2,7-辛二烯酸基金合欢酸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(1)和3-O-[β-D-吡喃阿拉伯糖基-(1→2)-β-D-吡喃呋糖基-(1→6)-β-D-葡萄糖基]-21-O-(6S)-2-反式-2,6-二甲基-6-O-[4-O-((6S)-2-反式-2,6-二甲基-6-O-β-D-吡喃鸡纳糖基-2,7-辛二烯酸基)-β-D-吡喃鸡纳糖基]-2,7-辛二烯酸基金合欢酸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(2),分别命名为合欢皂甙J14(JulibrosideJ14)和合欢皂甙J15(JulibrosideJ15)

Abstract: Two new diastereoisomeric saponins named as Julibroside J14and Julibroside J15were isolated from the dried stem barks of Albizia julibrissin. On the basis of chemical and spectral methods, their structures were elucidated as 3-O-[β-D-xylopyranosyl-(1→2)-β-Darabinonosyl-(1→6)-β-D-glucopyranosyl]-21-O-｛ (6S)-2-trans-2,6-dimethyl-6-O-[4-O-((6R)-2-trans-2,6-dimethyl-6-O-β-D-quinovopyranosyl-2,7-octadienoyl)-β-D-quinovopyranosyl]-2,7-octadienoyl｝ acacic acid 28-O-β-D-glucopyranosyl-(1→3) [α-L-arabinofuranosyl-(1→4)]-α-Lrhamnopyranosyl-(1→2)-β-D-glucopyranosyl ester (1) and 3-O-[β-Dxylopyranosyl-(1→2)-β-D-arabinopyranosyl-(1→6)-β-D-glucopyranosyl]-21-O-｛(6S)-2-trans-2,6-dimethyl-6-O-[4-O-((6S)-2-trans-2,6-dimethyl-6-O-β-D-quinovopyranosyl-2,7-octadienoyl)-β-D-quinovopyranosyl]-2,7-octadienoyl｝ acacic acid 28-O-β-D-glucopyranosyl-(1→3)-[α-Larabinofuranosyl-(1→4)]-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl ester(2), respectively.
