Abstract

Objective: Garcinia lateriflora Blume has been reported to have antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl method with methanol, ethyl acetate, and n-hexane leaves extract inhibitory concentration 50% (IC50) levels of 6.18, 8.03, and 156.8 µg/mL, respectively. Meanwhile, there has been no literature regarding G. lateriflora Blume’s lipoxygenase inhibition activity. The aim of this study was to determine the potential antioxidant activity and lipoxygenase inhibition activity of three leaf extracts of G. lateriflora Blume. Methods: These study test methods involved an assessment of antioxidant activity using the ferric reducing antioxidant power method, an assessment of lipoxygenase inhibition activity through the in vitro method, and a qualitative analysis of flavonoid and total flavonoid content using thin-layer chromatography and the AlCl3 colorimetric method to reveal the most active extract. Results: Based on the assessment for methanol, ethyl acetate, and n-hexane, the results showed that the effective concentration 50% levels of the antioxidant activity of G. lateriflora Blume leaves extract were 9.567, 16.555, and 50.550 µg/mL, respectively. Furthermore, the IC50 levels of the lipoxygenase inhibition activity were 0.693, 0.793, and 1.316 µg/mL, respectively. The most active extract for both of the tests was methanol extract, which has a total flavonoid content of 6.298 mg quercetin equivalents/g. Conclusions: Based on the test results, it can be concluded that G. lateriflora Blume leaves extracts exhibit antioxidant and lipoxygenase inhibition activities, with methanol extract as the most active extract, containing more flavonoid than the other two extracts.
