Abstract

The computer auxiliary partial least squares is introduced to simultaneously determine the contents of Deoxyschizandin, Schisandrin, γ-Schisandrin in the extracted solution of wuweizi. Regression analysis of the experimental results shows that the average recovery of each component is all in the range from 98.9% to 110.3%, which means the partial least squares regression spectrophotometry can circumvent the overlapping of absorption spectrums of multi-components, so that satisfactory results can be obtained without any sample pre-separation.
