A strategy for antioxidant quality evaluation of Aster yunnanensis based on fingerprint-activity relationship modeling and chemometric analysis
In this study, a fingerprint-activity relationship between ultrahigh performance liquid chromatography (UHPLC) fingerprints and antioxidant activity was established to evaluate the quality of Aster yunnanensis Animals Franch.(AYF) from different collecting spots.First, the fingerprint of AYF was established by UHPLC, and the similarity analysis was
