Abstract

Phytochemical screening test used 5% FeCl3 reagent showed extract become to black extract that saputangan leaves contained phenolic compound. Saputangan leaves powder was macerated with methanol and got macerate as 100.84 g. Macerate was dissolved with aquadest to remove lipid in saputangan leaves. First partition was used ethyl acetate to get solid extract as 37.03 g. Second Partition was used n-hexane to get solid extract as 18.25 g. Total phenolic was analysed on plate of thin layer chromatography with used chloroform and methanol with 70:30 comparison. Total phenolic has 3 spots that have an Rf of 0.44 ; 0.29 and 0.22. Total phenolic absorbance measured at 516 nm wavelength using a UV-Visible spectrophotometer. Total phenolic solutions were soluted in concentrations of 10, 25 and 50 ppm using methanol p.a as solvent. The absorbance obtained at all three concentrations was 0.202; 0.195 and 0.175. Based on the linear regression equation Y = 1,191 X + 31.87, the IC50 value for the total phenolic was 15.22 ppm. IC50 value of 15.22 ppm can be categorized as a total phenolic compound as a strong antioxidant.
