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