Daftar Isi:
- Effect of ethanol-water ratio as extraction solvent in gaining of extractive, phenolic content and antioxidant activity in Psidium guajava Linn. leaves have been investigated. The ethanol-water ratio tested were 100:0, 80:20, 70:30, 60:40, 50:50 and 40:60. Results revealed that ethanol-water ratio gave significant effect on extractive obtainability, phenolic content and antioxidant activity (p<0,05). Among the ethanol-water ratio tested, the best result was obtained by ethanol-water ratio 50:50 as extraction solvent for Psidium guajava Linn. leaves. Keywords : Antioxidant, Psidium guajava Linn., extraction solvent, phenolic compounds.
