OBJECTIVE
To separate chemical and active constituents from the stem bark of Albiza julibrissin.
METHODS
Chromatography and spectral methods were used.
RESULTS
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-[3-O-(6S)-2-trans-2-hydroxymethyl-6-methyl-6-hydroxy-2,7-octadienoyl)-beta-D-xylopyranosyl]-2,7-octadienoyl]-acacic acid-28-O-beta-D-glucopyranosyl-(1-->3)-[alpha-L-arabinofuranosyl-(1-->4)]-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl ester (1) was separated and identified.
CONCLUSION
Compound 1 is a new saponin named as Julibroside J(24).
目的
从合欢茎皮中分离化学和活性成分。
方法
采用色谱法和光谱法。
结果
分离并鉴定出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 - [3 - O - (6S) - 2 - 反式 - 2 - 羟甲基 - 6 - 甲基 - 6 - 羟基 - 2,7 - 辛二烯酰) - β - D - 吡喃木糖基] - 2,7 - 辛二烯酰] - 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）。
