【摘要】 从狗枣猕猴桃叶中分离出4个新的黄酮类化合物,经1D NMR,2D NMR及ESI-MS等波谱分析鉴定了其结构,分别是4′-甲氧基-槲皮素-7-O-(4″-O-乙酰基-鼠李糖基)-3-O-β-D-吡喃葡萄糖苷(1),山柰甲黄素-7-O-(3″-O-乙酰基-鼠李糖基)-3-O-芸香糖苷(2),山柰酚-7-O-(4″-O-乙酰基-鼠李糖基)-3-O-芸香糖苷(3)和4′-甲氧基-槲皮素-7-O-(4″-O-乙酰基-鼠李糖基)-3-O-芸香糖苷(4).更多还原

【Abstract】 Four new acetylated flavonoids,4′-methoxyl-quercetin-7-(4″-O-acetylrhamnosyl)-3-O-β-D-glucopyranoside(1),kaempferide-7-O-(3″-O-acetylrhamnosyl)-3-O-rutinoside(2),kaempferol-7-O-(4″-O-acetylrhamnosyl)-3-O-rutinoside(3),4′-methoxyl-quercetin-7-(4″-O-acetylrhamnosyl)-3-O-rutinoside(4) were isolated from the extracts of the leaves of Actinidia Kolomikta(Rupr.et Maxim.) Planch.Their structures were elucidated by application of chemical and spectroscopic analysis including HRESI-MS,1H-1H COSY,HMQC and HMBC.更多还原
