| 摘 要： | 岭回归 (RR)分光光度法是近年来发展起来的计算分光光度法之一。将RR分光光度法应用于五味子提取液中五味子甲素、五味子乙素、五味子醇甲等三组分含量的同时测定 ,运用计算机VB语言对实验数据进行RR分析。实验结果表明RR分光光度法对样品中各组分的平均回收率在 92 35 %～ 10 8 6 9%之间。样品不经分离即可同时测定 ,取得了满意的分析结果

| Abstract: | Ridge Regression (RR) spectrophotometry was used in the present paper to analyse three components: deoxyschizandin, schisandrin, and gamma-schisandrin. The basic principle and the analytical steps of the approach are described in detail. The computer program of RR is based on VB language. The experimental results show that the RR method has no systematical error as compared to classical method, and the average recovery of each component is all in the range of 92.35% to 108.69%. High accuracy of RR method was obtained. Each component was determined with satisfactory results without any pre-separation. As compared with conventional methods, this method is simple, rapid and suitable for the computer-aided analysis. It was developed in statistical literature to treat these ill-conditioned systems and is an useful analytical method. |
