Abstract

Quercitol, five saponins and 3-O-(6'-O-palmitoyl) beta-D-glucopyranosyl stigmasterol were isolated from the stem bark of Myrisine pellucida. These compounds are described for the first time in this plant and their structures were determined using a combination of 1H and 13C NMR, and mass spectroscopy. The two saponins are new compounds, 3-O-(alpha-L-rhamnopyranosyl (1-->2) beta-D-glucopyranosyl (1-->4) alpha-L-arabinopyranosyl) cyclamiretin A and 3-O-(beta-D-xylopyranosyl) (1-->2) beta-D-glucopyranosyl (1-->4) [beta-D-glucopyranosyl (1-->2)] alpha-L-arabinopyranosyl) cyclamiretin D.

摘要

从亮叶铁仔的茎皮中分离出了栎醇、五种皂苷和3 - O -（6'- O - 棕榈酰基）β - D - 吡喃葡萄糖基豆甾醇。这些化合物在该植物中首次被描述，其结构通过1H和13C核磁共振以及质谱联用技术得以确定。这两种皂苷是新化合物，分别为3 - O -（α - L - 鼠李糖基（1→2）β - D - 吡喃葡萄糖基（1→4）α - L - 阿拉伯糖基）环阿尔廷醇A和3 - O -（β - D - 木糖基）（1→2）β - D - 吡喃葡萄糖基（1→4）[β - D - 吡喃葡萄糖基（1→2）]α - L - 阿拉伯糖基）环阿尔廷醇D。
