Aktivitas antioksidan ekstrak sulur buah naga putih (Hylocereus undatus) dengan metode DPPH dan Rancimat
Abstract: The objectives of
this study were to analyze phytochemical components, to determine total phenol
and flavonoid content, and to test the antioxidant activity of dragon fruit
vine extract. The results of phytochemical analysis showed acetone and ethyl
acetate extracts contain alkaloids, flavonoids and steroids, while methanol
extracts contained alkaloids, flavonoids and triterpenoids. Total phenol and
flavonoid content determination results showed the highest concentration in
acetone extract of 460.01 GAE mg / 100 g sample and 229.27 RUE mg/100 g sample.
Extract of dragon fruit vine has a potencial as antioxidant by inhibition of
free radical of DPPH with best IC50 value on acetone extract 25.32 mg / L. The
results of antioxidant testing in lipid system using rancimat method obtained
the highest protection factor on methanol extract of 1.64.
