为了解芒果(Mangifera indica L.)的化学成分,从芒果叶70%乙醇提取物中分离鉴定了8个单体化合物,经波谱分析,分别鉴定为:5-(β-D-glucopyranosyloxy)-2-hydroxy benzoic acid methyl ester(1)、methyl salicylate glucoside(2)、对羟基苯甲酸(3)、nikoenoside(4)、(6R,9R)-3-oxo-α-ionol-β-D-glucopyranoside(5)、byzantionoside B(6)、icariside B2(7)和2-ethyl-3-methylmaleimide N-β-D-glucopyranoside(8)。化合物1、2、4~7均为首次从芒果属中分离得到,化合物8首次从该种中分离得到,化合物1的NMR数据是首次报道。
In order to understand the chemical constituents of Mangifera indica L., eight monomer compounds were isolated and identified from 70% ethanol extract of mango leaves. Their chemical structures were identified as 5- (β-D-glucopyranosyloxy) -2 -hydroxy benzoic acid methyl ester (1), methyl salicylate glucoside (2), p-hydroxybenzoic acid (3), nikoenoside (4), (6R, 9R) -3-oxo-α-ionol-β-D-glucopyranoside 5), byzantionoside B (6), icariside B2 (7) and 2-ethyl-3-methylmaleimide N-β-D-glucopyranoside (8). Compounds 1, 2, 4 ~ 7 were isolated from mango for the first time, and compound 8 was isolated from this species for the first time. The NMR data of compound 1 was first reported.
