<![CDATA[Arumanis mango rind (Mangifera indica L) usually becomes organic waste, but contains flavonoid secondary metabolites. Arumanis mango rind extract was chosen so that it can be used as an antioxidant compound, which is an antidote to free radicals. The aim of this research was to examine the antioxidant activity and toxicity tests of arumanis mango rind extract. The result is that the maximum absorption wave of DPPH is 518 nm, with an absorbance of 0.788. The results of comparative antioxidant activity for gallic acid obtained IC50 = 4.424 µg/mL, while the arumanis mango rind extract sample had an IC50 value = 18.294 µg/mL. For toxicity test results, the LC50 value = 169.043 µg/mL. Based on the research results obtained, it can be concluded that the antioxidant activity of arumanis mango rind extract is classified as very strong (<50 µg/mL) and the toxicity is classified as toxic (<1,000 µg/mL).]]>
