Garcinia hombroniana Pierre is one species of genus Garcinia that has been known have antioxidant antivity and has been used traditionally as antiinflammatory. The aim of this study was to obtain data of antioxidant activity and to observe potential inhibition of lipoxygenase activity that most active from methanolic, ethyl acetate, and n-hexane extracts with total flavonoids content from most active extracts from the bark of Garcinia hombroniana Pierre. The antioxidant activity was measured using ferric reducing antioxidant power (FRAP), anti-inflammatory assay was measured using inhibition of lipoxygenase activity test, and qualitative analysis of flavonoids using thin layer chromatography, with total flavonoids content was measured using AlCl3 colorimetic method.The results showed EC50 of antioxidant activity of methanolic, ethyl acetate, and n-hexane extracts respectively 27,21; 15,34; 110,9 μg/mL and IC50 inhibition of lipoxygenase activity respectively 0,95; 0,26; 5,09 μg/mL. Ethyl acetate extract was the most active extract with total flavonoids contents was 7,430 mg QE (quersetin equivalent)/g extract. The results of this study showed bark extract Garcinia hombroniana Pierre has antioxidant activity and potent to inhibit lipoxygenase activity.
