Sari

The research about the effect of microwave drying methods on content of phenolicÂ compounds and antioxidant activity of Gynura pseudochina,(Lour.) Merr. have been done. TheÂ determination of phenolic compounds was carried out according to Folin-Ciocalteu method andÂ antioxidant activity was evaluated by DPPH method, calculated as gallic acid equivalent (GAE).Â The research showed that the highest phenolic compounds and the strongest antioxidant activityÂ obtained by microwave drying method compared by air drying method. The phenolic compoundsÂ each gram sample by using microwave drying is 1.673 mg phenolic compounds and antioxidantÂ activities were calculated as the IC50 at concentration 2.876 mg/mL.
