摘要
采用超声波法从黄柏中提取黄色素。结果表明,黄柏黄色素的最大吸收波长为335nm。最适宜提取剂为乙醇。最佳提取条件为:提取剂浓度60%、提取剂pH3~7、提取温度0℃。该色素耐光、耐热性强,常用的食品添加剂以及金属离子Na+、Cu2+、Mg2+、Ca2+等对色素无明显影响。
The ultrasonic extraction method was used for extracting yellow pigment from Phellodendron chinense Schneid. bark. The yellow pigment has the maximum absorption at 335-um wavelength. The optimum extraction solvent is alcohol. The optimum extraction conditions are as follows: concentration of solvent 60%, pH 3 to 7 and extraction temperature 0℃. The pigment is quite stable, lightfast, heatproof and hardly affected by common food additives as well as Na+, Cu2+, Mg2+ and Ca2+.
