Abstract: In this study, antioxidant compounds from Ledum palustre L. leaves were screened and identified by using an online high-performance liquid chromatography (HPLC)-ABTS+· screening system. Two antioxidant compounds from the ethyl acetate fraction in methanol extract were obtained. By mass spectroscopy (MS) and nuclear magnetic resonance (NMR) spectroscopy, both compounds were identified as genistin and quercetin, respectively.
