Reactive radicals cause oxidative stress, leading to cell damage. Antioxidants can convert radicals into less reactive ones. Seburo leaf (Garcinia forbesii King) has the potential as a natural antioxidant containing flavonoids, phenolic compounds, saponins, tannins, triterpenoids and steroids. This study aims to determine the characteristics of ethanol extracts, the effect of giving ethanol ext…
