Abstract

Introduction: Antioxidant is one of the therapeutic strategies to overcome oxidative stress and inhibit synthesis of inflammatory mediators through lipoxygenase pathway. Garcinia is the largest of Clusiaceae family which has been proven to provide antioxidant and anti-inflammatory activity. Garcinia kydia Roxburgh is one of the plants of this genus which is known to have antioxidant activity but lipoxygenase inhibition activity from this plant was unknown. Methods: This study aimed to test antioxidant activity of the methanol, ethyl acetate and n-hexane extract from Garcinia kydia Roxburgh leaves by FRAP (Ferric Reducing Antioxidant Power) method, anti-inflammatory activity was tested by inhibiting lipoxygenase and total flavonoid content by colorimetric methods AlCl3. Results: The results showed an antioxidant activity of methanol extract, ethyl acetate and n-hexane leaves of Garcinia kydia Roxburgh have EC50 value, respectively 18,448; 12,389 and 31,260 μg/mL, and the lipoxygenase inhibition activity have IC50 value, respectively 0,556; 0,212 and 3,575 μg/mL. Ethyl acetate extract of Garcinia kydia Roxburgh leaves was the most active extract in this study which has total flavonoid content, 30,650 mgQE/ gram extract. Conclusion: The conclusion, Garcinia kydia Roxburgh has antioxidant and lipoxygenase inhibition activity, with ethyl acetate extract as the most active extract which contains total flavonoids.
