梅花 SIEB 鲜花的甲醇提取物及其馏分。等ZUCC。被发现对 1,1-二苯基苦基-2-肼基 (DPPH) 自由基和超氧化物具有清除作用。通过 GC-MS 分析梅花的香味成分，并从乙酸乙酯可溶部分中分离出一种新的多酰化蔗糖，即李子糖 III。根据化学和物理化学证据，确定了李糖 III 的结构为 4,3',4',6'-四-O-乙酰基-6-O-对香豆酰蔗糖。此外，还考察了主要成分对DPPH自由基和超氧化物的清除作用。
The methanolic extract and its fractions from the fresh flowers of Prunus mume SIEB. et ZUCC. were found to show scavenging effects on 1,1-diphenylpicryl-2-hydrazyl (DPPH) radical and superoxide. The fragrance constituents of P. mume were analyzed by GC-MS and a new polyacylated sucrose, prunose III, was isolated from the ethyl acetate-soluble fraction. The structure of prunose III was determined on the basis of chemical and physicochemical evidence as 4,3',4',6'-tetra-O-acetyl-6-O-p-coumaroylsucrose. In addition, the scavenging effects of the principal constituents on DPPH radical and superoxide were examined.
