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.

Key words: chestnut kernel, pigment, constituent, analysis
