胀果甘草中2个新的二氢黄酮甙

TWO NEW FLAVANONE GLYCOSIDES FROM GLYCYRRHIZIA INFLATA

摘要: 从胀果甘草(Glycyrhizia inflata Bat.)根茎的95%醇提取部分经HPLC分得两个新的二氢黄酮二糖链甙,经化学和波谱分析,将其结构分别确定为甘草素-7-O-β-D-呋喃芹糖-4′-O-β-D-吡喃葡萄糖甙(liquiritigenin-7-O-β-D-apiofuranosyl)-4′-O-β-D-glucopyranoside(I)和甘草素-7-O-β-D-(3-O-乙酰基)呋喃芹糖-4′-O-β-D-吡喃葡萄糖-甙liquiritigenin-7-O-β-D-(3-O-acetyl)-apiofuranosyl-4′-O-β-D-glucopyra-noside(I)。

Abstract: Two new flavanone glycosides having two chains of sugar moeity were isolated from the roots of Glycyrrhizia inflata Bat by repeated CC and HPLC. They were identified to be liquiritigenin-7-O-β-D-apiofuranosyl-4'-O-β-D-glucopyranoside(I) and liquiritigenin-7-O-β-D-(3-O-acetyl)-apiofuranosyl-4'-O-β-D-glucopyranoside(II) on the basis of chemical and spectroscopic methods.
