摘要: | 目的:研究青果氯仿萃取部位的化学成分。方法:采用小孔吸附树脂、Toyopear1 HW-40F凝胶树脂、反相C18、Sephadex LH-20凝胶树脂柱对青果氯仿萃取部位进行分离纯化,根据理化性质和波谱数据(质谱、氢谱、碳谱)分析鉴定化合物结构。结果:从青果氯仿萃取部位中分离得到8个化合物,分别鉴定为二氢红花菜豆酸3′ -O-β-D-葡萄糖苷(1)、3,4-二羟基苯甲酸(2)、3-O-没食子酰奎尼酸(3)、没食子酸(4)、没食子酸乙酯(5)、东莨菪内酯(6)、鞣花酸-4-O-α-L-吡喃鼠李糖苷(7)、异柯里拉京(8)。结论:化合物1、2、7为首次从青果中分离得到;该研究为青果的质量评价奠定了一定基础。 |
ABSTRACT: | OBJECTIVE: To study the chemical constituents in the chloroform extract of Fructus Canarii. METHODS: The chloroform extract of Fructus Canarii was isolated and purified by MCI, Toyopearl HW-40F, reverse-phase C18, Sephadex LH-20 column. The structure of compounds was analyzed and identified by physicochemical properties and spectral data (mass spectrum, hydrogen spectrum and carbon spectrum). RESULTS: Eight compounds were isolated from chloroform extract of Fructus Canarii, namely Dihydrophaseicacid-3′ -O-β-D-glucopyranoside(1), 3,4-Dihydroxybenzoic acid(2), 3-O-galloylquinic acid(3), Gallic acid (4), Ethyl gallate(5), Scopoletin(6), Dllagic acid-4-O-α-L-rhamnopyranoside(7) and Isocorilagin(8). CONCLUSIONS: Compounds 1, 2 and 7 were firstly obtained from Fructus Canarii. The study lays foundation for quality evaluation of Fructus Canarii. |
