Effects of drying methods in gaining of extracted material, phenolic content, and antioxidant activity in Psidii folium leaves have been investigated. The drying methods tested were air-drying, microwave oven-drying, and oven-drying at 60ºC. The determination of extracted material compound showed that the air-drying, microwave oven-drying, and oven-drying at 60ºC contained 184,767; 333,767; and 208,533 mg/g, phenolic of these sample were  46,0474; 53,8402; and 51,4532 mg/g, and IC50 of these sample were 0,529; 0,477; and 0,505 mg/mL. Among the drying methods tested, the highest extracted material, phenolic concentration, and antioxidant activity were by microwave oven-drying.
