采用紫外-可见分光光度法测定白刺色素和黑果枸杞色素中的花色苷和总多酚的含量,白刺色素的花色苷和总多酚含量分别为4.6、0.10mg/g,黑果枸杞色素的花色苷和总多酚含量分别为14.6、0.22mg/g。该方法操作简单、灵敏度高,适宜检测花色苷和总多酚的含量。该实验为以后的白刺色素和黑果枸杞色素的开发与利用提供理论依据。 The contents of anthocyanins and total polyphenols in white pigment and black fruit of Lycium barbarum were determined by UV-Vis spectrophotometry. The contents of anthocyanins and total polyphenols in white pigment were 4.6 and 0.10 mg / g, respectively. Pigment anthocyanins and total polyphenols were 14.6,0.22mg / g. The method is simple, high sensitivity, suitable for detecting anthocyanins and total polyphenols content. The experiment provides the theoretical basis for the development and utilization of the white pigment and black fruit lycium pigment.
