将偏最小二乘（ Ｐ Ｌ Ｓ）法同紫外可见分光光度法结合， 快速分析黑加仑色素的含量． 讨论主成分数对 Ｐ Ｌ Ｓ定量预测能力的影响， 并对校正集样品和预测集样品中黑加仑色素含量进行定量预测．
Partial Least Squares (PLS) method combined with UV-Vis spectrophotometry for rapid analysis of blackcurrant pigment content. The effects of principal components on the quantitative prediction ability of P L S were discussed. The content of black currant pigment in the calibration samples and the prediction samples was quantitatively predicted.
