| Abstract: | The extraction and antioxidant activity of total polyphenols from Ampelopsis grossedendata were studied in this paper. The optimal extraction conditions were achieved to be extraction at 75 ℃ for 1.5 h with a 25-fole volume of 50% acetone aqueous solution as the extraction solvent. Under the optimal extraction conditions, the yield of total polyphenols was 21.82%. Total polyphenols from Ampelopsis grossedendata showed high reducing power and excellent scavenging effect on hydroxyl, superoxide anion and DPPH free radicals in a dose-dependent manner. |
