Abstract: Peak shift correction(PSC) was applied to HPLC signals of traditional Chinese medicine in order to strengthen the trilinearity of the data, which was particularly useful in analyzing three-way data. The usefulness of PSC on parallel factor analysis(PARAFAC) solutions was examined by means of an example of HPLC-DAD data of the traditional Chinese medicine Yanhusuo and the results were compared with the typical multivariate curve resolution(MCR-ALS) method.
