The methanolic extract from the flower buds of Prunus mume, cultivated in Zhejiang province, China, showed an inhibitory effect on aldose reductase. From the methanolic extract, five new acylated sucroses, mumeoses F-J, were isolated together with 29 known compounds. The chemical structures of the new compounds were elucidated on the basis of chemical and physicochemical evidence. The inhibitory effects
在中国浙江省栽培的梅花的花蕾中,甲醇提取物对醛糖还原酶具有抑制作用。从甲醇提取物中分离出五种新的酰化蔗糖,Moseoses FJ,以及29种已知化合物。在化学和物理化学证据的基础上阐明了新化合物的化学结构。还研究了分离的化合物对醛糖还原酶的抑制作用。酰化的奎宁酸类似物,它是梅毒(P. mume)花芽的主要化合物之一,显示出基本上抑制醛糖还原酶的作用。特别地,发现了甲酸M-具有强的抑制作用[IC50 =0.4μm]。
