摘　　要：分别采用高效液相色谱法和紫外分光光度计法测定红米红中矢车菊-3-葡萄糖苷含量和色价,应用线性回归分析法对红米红色价和矢车菊-3-葡萄糖苷含量水平之间的相关性进行了研究。结果表明:红米红色价与矢车菊-3-葡萄糖苷含量呈显著正相关,粉末样品的矢车菊-3-葡萄糖苷含量与色价之比略高于液体样品。红米红液体样品每1色价相当于每100mL样品含有(91.40±0.15)mg矢车菊-3-葡萄糖苷,变异系数为3.17%,相关系数为0.9983;粉末样品每1色价相当于每100g样品含有(102.10±0.21)mg矢车菊-3-葡萄糖苷,变异系数为0.38%,相关系数为0.9953。良好的线性回归方程说明可以通过测量红米红色价简单推算其矢车菊-3-葡萄糖苷含量水平,为广大中小企业红米红的产品质量控制提供科学依据。The cyanidin-3-glucoside content and color value of red kernel color （RKC） were detected by HPLC method and UV spectrophotometry, respectively. The correlation between both parameters was analyzed by linear regression. The results showed that the two parameters were positively correlated, and cyanidin-3-glucoside content and color value were slightly higher in powder samples than in liquid ones. For liquid samples, color value of 1 referred to （91.40 ± 0.15） mg of cyanidin-3-glucoside in 100 mL of samples, with the variation coefficient of 3.17% and the correlation coefficient of 0.9983. For powder samples, color value of 1 represented （102.10 ± 0.21） mg of cyanidin-3-glucoside in 100 g of samples, with the variation coefficient of 0.38% and the correlation coefficient of 0.9953. Good linearity indicated that the content of cyanidin- 3-glucoside in RKC could be simply calculated through determining its color value, thereby providing a theoretical basis for quality control of RKC in small and medium enterprises.
