Abstract

One of the ways to prevent generative diseases is by using natural antioxidant compounds. The flavonoid compounds in the flower parts of M. gigantea have a role in antioxidants. Thus the study aimed to test the antioxidant activity and flavonoid levels of M. gigantea flowers. The antioxidant test was carried out by UV-vis spectrophotometry using 2,2-diphenyl-1-picrylhydrazyl and flavonoid assay using 10% aluminum chloride and potassium acetate, both tests using quercetin as a comparison. The results of this test obtained IC50 antioxidants 145,725 ± 3.858 ppm, and flavonoids were 1,860 ± 0.007% w/w eq quercetin. The conclusion from the experiments that have been carried out is that M. gigantea flowers have moderate antioxidant abilities.
