Abstract

Gaharu (agarwood) grows naturally in forest and cultivately by people in their farm area. The purposes of this research were to known the chemical compound and antioxidant activity of the gaharu leaf that grows naturally and cultivatelly. As 2 of gaharu leaves were identified, then processed into leaf simplicia, and extracted with 96% ethanol solvent. Gaharu extracted were tested through several testing such as; phytochemical screening, antioxidant activity, and hedonic method. Phytochemical screening showed no the different contain in gaharu leaves that naturally (Wikstroemia tenuiramis) or cultivately (Aquilaria malaccensis) grown, gaharu leaves positive contain flavonoid, glycosides, steroids/triterpenoids and tannins compounds. The results of antioxidant activity test showed that agarwood leaf extract that grows naturally and cultivately has IC50 value in 30.482 dan 41.130 μg/ml which very strong antioxidant activity category. Hedonic tests was on 3-4 scale with the like moderately category, feasible to be developed as an alternative tea.
