采用毛细管区带电泳法测定了 10种中国产葡萄籽中的 4个主要儿茶素类化合物 :(+)儿茶素、(- )表儿茶素、(± )表没食子儿茶素、(± )表儿茶素没食子酸酯的含量。在 0 0 2mol/L硼砂和 0 0 0 5mol/L磷酸盐的混合缓冲体系 (pH 10 0 )的背景缓冲液中 ,4个化合物在 10min内取得了令人满意的分离。迁移时间的重现性(RSD)小于 2 % ,峰面积的重现性 (RSD)小于 5 %。在质量浓度为 0 0 0 5g/L～ 0 5 g/L时 ,线性相关系数大于0 995。检测限为 3mg/L～ 10mg/L。该方法简单、快速、准确 ,可作为葡萄籽分析和药用开发过程中分析儿茶素类化合物的有效方法推广使用 Four main catechins from 10 Chinese-made grape seeds were determined by capillary zone electrophoresis. They were (+) catechin, (-) epicatechin, (±) epigallocatechin, ±) epicatechin gallate content. In the background buffer of 0 2mol / L borax and 0 0 0 5mol / L phosphate mixed buffer system (pH 10), 4 compounds achieved satisfactory separation in 10min. Reproducibility times (RSDs) were less than 2% and peak area reproducibility (RSD) was less than 5%. At mass concentration of 0 0 0 5 g / L ~ 0 5 g / L, the linear correlation coefficient is greater than 0 995. The detection limit is 3mg / L ~ 10mg / L. The method is simple, rapid and accurate and can be used as an effective method for the analysis of catechins in grape seed analysis and medicinal development.
