前文连续报道自乌拉尔甘草(Glycyrrhiza uralensis Fisch)的干燥叶中分得7个黄酮甙元、7个酚酸和黄酮甙类成分。本文继续报道该植物叶中的两个带有异戊烯基的黄酮类化合物的分离和鉴定,根据化学试验和光谱分析,分别确定结构为3,5,7,4′-四羟基-3′-甲氧基-6-异戊烯基黄酮(Ⅰ)和5,7,3′,4′-四羟基-8-异戊烯基二氢黄酮(Ⅱ)。Ⅰ是新化合物,命名为甘草宁P-3′-甲 Previously, it was reported that 7 flavonoid aglycones, 7 phenolic acids and flavonoid anthraquinones were extracted from dry leaves of Glycyrrhiza uralensis Fisch. This article continues to report the isolation and identification of two isopentenyl-containing flavonoids from the leaves of the plant. According to chemical tests and spectroscopic analysis, the structures were determined to be 3,5,7,4’-tetrahydroxy-3’, respectively. -Methoxy-6-prenyl flavone (I) and 5,7,3’,4’-tetrahydroxy-8-prenylflavanone (II). I is a new compound named Glycyrrhizin P-3′-A
