Objective:
To explore the utility of principal component analysis (PCA) in conjunction with the window preprocessing scheme on chromatographic data for quality control.
Method:
Chromatographic fingerprints of processed tuber of Pinellia pedatisecta were determined by HPLC, and the Window Preprocessing and PCA were used for data processing.
Result:
The quantitative differences among different growing areas and different process batches were found with this method.
Conclusion:
The method can be used in quality control for monitoring between-batch products of traditional Chinese pharmaceutical process.
