Pengaruh Cara Pengeringan dengan Microwave terhadap Perolehan Kadar Senyawa Fenolat dan Aktivitas Antioksidan dari Daun Dewa (Gynura pseudochina (Lour.), Merr.)
Abstract: The research about
the effect of microwave drying methods on content of phenolic compounds and
antioxidant activity of Gynura pseudochina,(Lour.) Merr. have been done. The
determination of phenolic compounds was carried out according to
Folin-Ciocalteu method and antioxidant activity was evaluated by DPPH method,
calculated as gallic acid equivalent (GAE). The research showed that the
highest phenolic compounds and the strongest antioxidant activity obtained by
microwave drying method compared by air drying method. The phenolic compounds
each gram sample by using microwave drying is 1.673 mg phenolic compounds and
antioxidant activities were calculated as the IC50 at concentration 2.876
mg/mL.
