4种余甘子功能成分的分析

Study on Several Health Care Components in Flesh of Four Emblic Varieties

利用高效液相、气相／质谱、原子荧光等方法，测定了产自广东的柿饼、双鹅、甜种和土种4种余甘子果肉中的几种核苷、绿原酸、表儿茶素、芦丁、维生素C和微量元素。结果表明：余甘子果肉中含有微量的硒，含量（鲜重）为0．0014-0．0027mg／kg；余甘子果肉中的甲醇提取液中气相／质谱仅测出饱和脂肪酸；余甘子果肉中含有少量的核苷类物质肌苷、鸟苷和腺苷，含量（鲜重）分别为：3．7990-15．3600、1．1335-2．8935、0．0000-4．1768μg／g，土种中含有少量胸苷，含量为3．3199／μg／g；余甘子果肉中还含有绿原酸、表儿茶素和芦丁，含量（鲜重）分别为0．1123-0．2631、0．9486-2．2451、0．0467-0．2907mg／g，表儿茶素含量最高。

Several nucleosides,chlorogenic acid, epicatechin, rutin, Vitamin C and minim elements in flesh of four emblie （Phyllanthus emblica L. ） varieties （Shibing, Shuange, Tianzhong and Tuzhong） from Guangdong Province were determined by HPLC,GC/MS and atom fluorescence instrument etc. It showed that the content of Se was between 0. 001 4-0. 002 7 mg/kg（fresh weight,FW） . Only saturachlorogenic acid, epicateehin and rutin were investigated by HPLC. It proved that some nucleosides were present with inosine 3. 799 0- 15. 360 0 μg/g, guanosine 1. 133 5 - 2. 893 5 μg/g and adenosine 0. 000 0-4. 176 8 μg/g. A little thymidine was detected and its content was 3. 319 9 μg/g in flesh of Tuzhong variety. The contents of ehlorogenie acid, epicateehin and rutin were respectively 0. 112 3- 0. 263 1, 0. 948 6-2. 245 0,0. 046 7-0. 290 7 mg/g. The flesh was characteristic of high content of epicatechin.
