Abstract

Three sinapoyl glycosides have been isolated from the roots of Polygala virgata. The structures were established on the basis of UV, mass 1H and 13C NMR spectral data, including homonuclear and heteronuclear 2D shift correlation and selective INEPT experiments. alpha-D-(3-O-Sinapoyl)fructofuranosyl-alpha-D-(3-O-acetyl-6-O-s inapoyl)glucopyranoside and beta-D-(3,O-sinapoyl)fructofuranosyl-alpha-D-(4-O-acetyl-6-O-si napoyl)glucopyranoside are new natural products, whereas beta-D-(3-O-sinapoyl)fructofuranosyl-alpha-D-(6-O-sinapoyl) glucopyranoside has already been reported from other plants.

摘要

从黄花远志根中分离出了三种芥子酰糖苷。根据紫外光谱、质谱、¹H和¹³C核磁共振光谱数据确定了其结构，包括同核和异核二维位移相关以及选择性INEPT实验。α-D-(3-O-芥子酰)呋喃果糖基-α-D-(3-O-乙酰基-6-O-芥子酰)吡喃葡萄糖苷和β-D-(3,O-芥子酰)呋喃果糖基-α-D-(4-O-乙酰基-6-O-芥子酰)吡喃葡萄糖苷是新的天然产物，而β-D-(3-O-芥子酰)呋喃果糖基-α-D-(6-O-芥子酰)吡喃葡萄糖苷已在其他植物中报道过。
