Abstract

Two new triglycosides, kaempferol-3-O-[(4-beta-D-apiofuranosyl)-alpha-L- rhamnopyranoside]-7-O-alpha-L-rhamnopyranoside and kaempferol-3-O-[(4-beta-D-xylopyranosyl)-alpha-L-rhamnopyranoside]-7-O- alpha-L-rhamnopyranoside were isolated from the methanol extract of Chenopodium murale, together with a known diglycoside, kaempferol-3-O-beta-D-glucopyranoside-7-O-alpha-L-rhamnopyranoside. The characterization of the three compounds was achieved by various spectroscopic methods.

摘要

从藜的甲醇提取物中分离出两种新的三糖苷，山柰酚-3-O-[(4-β-D-芹菜呋喃糖基)-α-L-鼠李吡喃糖苷]-7-O-α-L-鼠李吡喃糖苷和山柰酚-3-O-[(4-β-D-木糖吡喃糖基)-α-L-鼠李吡喃糖苷]-7-O-α-L-鼠李吡喃糖苷，以及一种已知的二糖苷，山柰酚-3-O-β-D-葡萄糖吡喃糖苷-7-O-α-L-鼠李吡喃糖苷。通过各种光谱方法对这三种化合物进行了表征。
