Abstract: To optimize the reflux extraction process of caftaric acid and cichoric acid in Echinacea purpurea, ethanol concentration, extraction temperature, extraction time, and antioxidant amount were optimized by orthogonal experiments. And the addition of antioxidants on the extraction result was evaluated by comparative tests. The results showed that optimized conditions were extracted by 25% ethanol aqueous solution at 80 ℃ for 90 min. The addition of antioxidant had no significant effect on the extraction result. The optimized conditions of reflux extraction were applicable to the extraction of caftaric acid and cichoric acid in E. purpurea. It was not necessary to add antioxidant in extraction.
