摘要: 板栗仁色素为脂溶性黄色素,通过薄层板层析和柱层析,分离出两种黄色素,其Rf值分别为0.38、0.96。它们的紫外吸收波长分别为441、473、220nm和423、446、471、296、220nm。高效液相分析结果表明:板栗仁黄色素为叶黄素和胡萝卜素,鲜板栗仁中叶黄素含量为0.42mg/100g,β-胡萝卜素的含量为0.16mg/100g。

Abstract:  The pigments in chestnut kernels are fat-soluble yellow pigment, which are separated into two sorts of yellow pigments by TLC and column chromatography separation, their Rf values 0.38 and 0.96 respectively. Their absorption wave length are 444, 473, 220 nm and 423, 446, 471, 296, 220 nm respectively. The yellow pigments in chestnut kernels are composed of lutein and β-carotene by HPLC analysis, and their contents are 0.42 mg/100g and 0.16 mg/100g, respectively.
