Potensi Ekstrak Daun Tin (Ficus carica L.) sebagai Antioksidan dan Aktivitas Hambatannya terhadap Proliferasi Sel Kanker HeLa

Abstract

Fig fruit (Ficus carica L.) has antioxidant dan anticancer properties both empirically and scientific reseach. However, scientific research on the use of fig leaf as anticancer has not reported yet. This study examined the antioxidant and anticancer protency of fig leaf extract. Based on the phytochemicals test, simplicia of fig leaf contains flavonoids, tannins, steroids and alkaloids. Flavonoids, tannins, steroids of fig leaf were extracted by maceration technique using suitable solvent. The extracts were tested by 1,1-diphenyl-2-picrylhydrazyl antioxidant method and brine shrimp lethality test toxicity method. Flavonoid extract showed highest antioxidant activity with IC50 150 mg/L, while the LC50 for toxicity tests was 191.43 ppm. Flavonoids extract of fig leaf was fractionated using preparative thin layer chromatography and obtained seven fractions.Proliferation inhibition test against HeLa cancer cell by 3-[4,5-dimethylthiazol-2yl]-2,5-diphenyl tetrazolium bromide method showed the most active fraction was fraction F7 which inhibit 57.18 % proliferation of HeLa cancer cells at concentrations of 800 ppm. Based on the identification using ultraviolet spectrophotometer and fourier transform infrared, F7 fraction suspected to contain isoflavones or flavones compounds.
