Two new flavonoids were isolated from the flowers of Punica granatum Linn. (Punicaceae) along with the known compounds ellagic acid, gallic acid, sucrose, and gallic acid glycoside. The structures of the new flavonoids have been characterized as 5,6,7,8,2′,3′,5′-heptahydroxy-4′-methoxyflavanone (punicaflavanol) and 5,6,7,8,2′,5′-hexahydroxy-4′-methoxyflavanone-7-β-D-xylopyranoside (granatumflavanyl xyloside) on the basis of spectral data analyses and chemical reactions.
从石榴(Punica granatum Linn.)的花朵中分离出两种新的黄酮类化合物,以及已知的鞣花酸、没食子酸、蔗糖和没食子酸苷。根据光谱数据分析和化学反应,新黄酮类化合物的结构被确定为5,6,7,8,2′,3′,5′-七羟基-4′-甲氧基黄烷酮(punicaflavanol)和5,6,7,8,2′,5′-六羟基-4′-甲氧基黄烷酮-7-β-D-木糖苷(granatumflavanyl xyloside)。
