【摘要】 采用柱层析法分离分析红辣椒色素中的辣红素和辣黄素。以硅胶为固定相，丙酮、９５％乙醇分别作为辣红素和辣黄素的洗脱剂，每次分离的色素量为硅胶质量的１２５～１５０，分离后的液体经减压蒸馏得到浓缩产物。更多还原

【Abstract】 A column chromatographic determination was made for the seperation of yellow pigment from red capsicum annuum pigment. The solid phase was silica gel, acetone the eluting reagent of red capsaicin and 95% alcohol the eluting reagent of yellow capsaicin. The amount of sample for each seperation ranged from 1/25 to 1/50 of the amount of silica gel. After seperation, the eluting liquid was concentrated by decompressed distillation.更多还原
