Abstract

To study the chemical constituents of Peperomia dindygulensis Miq. , chromatography was used to isolate and purify the chemical constituents, their structures were elucidated by spectroscopic data and physical-chemical properties. Three compounds were obtained. They were identified as: hypolacetin-4',7-dimethyl ether-8-O-beta-D-glucopyranoside (I) , isoscutellarein-4'-methyl ether-8-O-alpha-L-arabinopyrano-syl-(1--> 4)-beta-D-glucopyranoside ( II) , isoscutellarein-4', 7-dimethyl ether-8-O-alpha-L-arabinopyranosyl-(1-->4) -betea-D-glucopyranoside (III). Compounds I, II and III are all new compounds.

摘要

为研究细辛叶豆瓣绿的化学成分，采用色谱法分离纯化其化学成分，并通过光谱数据和理化性质阐明其结构。得到了3个化合物，分别鉴定为：异百部定-4′,7-二甲醚-8-O-β-D-吡喃葡萄糖苷（Ⅰ）、异灯盏乙素-4′-甲醚-8-O-α-L-阿拉伯吡喃糖基-(1→4)-β-D-吡喃葡萄糖苷（Ⅱ）、异灯盏乙素-4′,7-二甲醚-8-O-α-L-阿拉伯吡喃糖基-(1→4)-β-D-吡喃葡萄糖苷（Ⅲ）。化合物Ⅰ、Ⅱ和Ⅲ均为新化合物。
