摘要: 为了充分利用我国油橄榄(Olea europaea L.)叶资源,丰富油橄榄叶化学成分的多样性。本文对油橄榄叶的化学成分进行研究,利用硅胶柱层析、重结晶等方法从其乙醇(95%)提取物的乙酸乙酯部位中分离得到了12个黄酮类化合物。通过1H NMR和13C NMR鉴定了它们的结构,分别为芹菜素(1)、木犀草素(2)、芦丁(3)、芹菜素-7-O-葡萄糖苷(4)、槲皮素(5)、香叶木素-7-O-葡萄糖苷(6)、香叶木素(7)、山柰酚(8)、花旗松素(9)、木犀草苷(10)、异鼠李素(11)、表没食子儿茶素没食子酸酯(12),其中化合物12为首次从油橄榄叶中分离得到。本研究为油橄榄叶的进一步开发和合理利用提供了试验基础。

Abstract:

In order to maximize the potential of Olea europaea leaf resources and increase the variety of chemical components found in O. europaea leaves.In this study,the chemical makeup of O. europaea leaves was examined,and using silica gel column chromatography and other methods,12 flavonoids were extracted from the ethyl acetate portion of ethanol (95%) extract.Their structures were identified as apigenin (1),luteolin (2),rutin (3),apigenin-7-O-glucoside (4),quercetin (5),diosmetin-7-O-glucoside (6),diosmetin (7),kaempferol (8),taxifolin (9),luteoloside (10),isorhamnetin (11),epigallocatechin gallate (12),by 1H NMR and 13C NMR,compound 12 was isolated from the leaves of O. europaea for the first time.The study has provided test basis for the further development and reasonable application of the O. europaea leaves.

Key words: leaves of Olea europaea, flavone, chemical composition, isolation and purification, structural identification
