Abstract:
An on-line HPLC-DPPH system was developed to determine the antioxidant activity of 16 batches of Polygoni Multiflori Radix Praeparata. By analyzing the chromatographic and biological activity fingerprints of 16 batches of Polygoni Multiflori Radix Praeparata, the dose-effect relationship was established and the total antioxidant activity was quantified by activity addition.The results suggested that the online HPLC-DPPH method can evaluate the antioxidant activity of different bathches of Polygoni Multiflori Radix Praeparata, with different processing methods, aiming to provide datasupport and scientific basis forquality evaluation of Polygoni Multiflori Radix Praeparata.
