Abstract

Three new triterpenoid saponins, proacaciaside-I, proacaciaside-II and acaciamine isolated from the fruits of Acacia auriculiformis, were identified as acacic acid lactone-3-O-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranoside, acacic acid lactone-3-O-alpha-L-arabinopyranosyl (1 --> 2)-beta-D-glucopyranoside and acacic acid lactone-3-O-alpha-L-arabinopyranosyl (1 --> 6)-2-acetamide-2-deoxy-beta-D-glucopyranoside based on their spectral properties and some chemical transformations.

摘要

从耳荚相思树果实中分离出的三种新三萜皂苷，原阿拉伯糖苷-I、原阿拉伯糖苷-II和阿拉伯胺，根据它们的光谱性质和一些化学转化，被鉴定为金合欢酸内酯-3-O-β-D-吡喃葡萄糖基（1→6）-β-D-吡喃葡萄糖苷、金合欢酸内酯-3-O-α-L-阿拉伯吡喃糖基（1→2）-β-D-吡喃葡萄糖苷和金合欢酸内酯-3-O-α-L-阿拉伯吡喃糖基（1→6）-2-乙酰胺-2-脱氧-β-D-吡喃葡萄糖苷。
