Abstract

Two new phenolic glycosides were isolated from the seeds of Cucurbita moschata. Their structures were elucidated as (2-hydroxy)phenylcarbinyl 5-O-benzoyl-beta-D-apiofuranosyl(1-->2)-beta-D-glucopyranoside (1) and 4-beta-D-(glucopyranosyl hydroxymethyl)phenyl 5-O-benzoyl-beta-D-apiofuranosyl(1-->2)-beta-D-glucopyranoside (2) on the basis of spectroscopic analysis and chemical evidence.

摘要

从南瓜种子中分离出两种新的酚苷。基于光谱分析和化学证据，它们的结构被鉴定为(2-羟基)苯基甲醇5-O-苯甲酰基-β-D-芹菜呋喃糖基(1→2)-β-D-吡喃葡萄糖苷(1)和4-β-D-(吡喃葡萄糖基羟甲基)苯基5-O-苯甲酰基-β-D-芹菜呋喃糖基(1→2)-β-D-吡喃葡萄糖苷(2)。
