Abstract

From the leaves of Helicia cochinchinensis, collected on Okinawa Island, seven phenolic glucosides and two terpenic glucosides were isolated. Five of the phenolic glucosides were previously known, being identified with p-coumaric and ferulic acids glucosyl esters, rhodioloside, helicidiol, and naringenin 5-O-beta-D-glucopyranoside. The structures of two other phenolic glucosides, named heliciosides A and B, were elucidated to be 5-O-beta-D-glucosides of 3-hydroxyflavanone, namely aromadendrin and taxifolin, by means of spectroscopic analyses. The two terpenic glucosides were identified with ampelopsisionoside and icariside C1.

摘要

从冲绳岛采集的越南厚壳桂叶片中，分离出了七种酚苷和两种萜苷。其中五种酚苷是已知的，分别鉴定为对香豆酸和阿魏酸的葡萄糖酯、红景天苷、厚壳桂二醇和柚皮素5-O-β-D-葡萄糖苷。通过光谱分析，另外两种酚苷（命名为厚壳桂苷A和B）的结构被阐明为3-羟基黄烷酮的5-O-β-D-葡萄糖苷，即圣草酚和紫杉叶素。两种萜苷分别鉴定为蛇葡萄素和淫羊藿苷C1。
