摘要：In this research, comprehensive phytochemical profile and antioxidant activities of four different varieties of Chimonanthus praecox were studied. The petal samples were analyzed by UHPLC-QTOF-MS and 50 compounds were identified. In addition, six possible markers responsible for discrimination among different varieties were indicated. Moreover, the assays such as DPPH, ABTS and FRAP revealed their high antioxidant activities. The samples of new varieties had the higher antioxidant activities than the traditional one, well correlated with their higher total fiavonoid and phenolic contents. This study presents the first phytochemical profile work on C. praecox, and gives insights into its potential application as natural antioxidant in the industries related to pharmaceutical and functional ingredients.
