【摘要】 通过试验初步确定了提取分离大蒜绿变色素的方法 :体积分数 75 %乙醇提取绿变色素 ,色素经弱阳离子交换树脂CG 5 0 ,sephadexLH 2 0柱层析分离 ,得到了构成绿变色素的蓝色素和黄色素 2条色带 ,两者的最大吸收波长分别为 5 90nm和 440nm。通过试验证明了黄色素为蓝色素转化而来。更多还原

【Abstract】 T A method for isolating the green pigment in greening garlic was developed. The pigment was extracted with 75% ethanol and isolated by column chromatography with Amberlite CG-50 and Sephadex LH-20. The green pigment was separated into blue pigment and yellow pigment, which showed a maximum absorbance at 590 nm and 440nm respectively. The experiments also demonstrated that the yellow pigment was transformed from the blue pigment.更多还原
