Determination of flavonoid levels of Macaranga gigantea and its activity as antioxidants

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