Abstract

Currently, various diseases are developing, ranging from mild to severe. One cause of these various diseases is free radicals. The negative impact of free radicals can be overcome with antioxidant compounds. One type of secondary metabolite with antioxidant activity is flavonoids. The leaves and peel of the langsat fruit (Lansium domesticum Corr.) are known to contain flavonoids, which can act as antioxidants. The aim of this study was to compare the flavonoid content and antioxidant activity of leaf and peel extracts of langsat fruit (Lansium domesticum Corr.) from South Kalimantan. Antioxidant testing used the DPPH (2-2-Diphenyl-1-Picryhydrazyl) method, and flavonoid levels were determined using UV-Vis spectrophotometry. The total flavonoid content of the langsat leaf extract and langsat fruit peel extract was 28.296 ± 0.092 and 41.09 ± 0.000, respectively. Based on the mean ± SD values, vitamin C, langsat leaf extract, and langsat fruit peel extract exhibited antioxidant activities of 5.46 ± 1.177, 76.416 ± 0.104, and 48.014 ± 1.451, respectively, which were categorized as very strong, strong, and very strong antioxidants.
