Abstract

This research aims to determine the tannin content in the ethanol extract of kebo rubber leaves (Ficus elastica Roxb. ex Hornem). Rubber plants (Ficus elastica Roxb. ex Hornem) are plants that are widely used as traditional medicine, the leaves of this plant are used as medicine to treat diarrhea. , stops bleeding and treats hemorrhoids. Many of the benefits and properties of the kebo rubber plant (Ficus elastica Roxb. ex Hornem) cannot be separated from the compounds contained in it, such as phenolics, tannins, flavonoids and saponins. Simplicia was extracted using the maceration method with 96% concentration of ethanol solvent for 3x24 hours. Determination of tannin content using the UV-Vis spectrophotometric method, with a maximum wavelength of 772 nm, using gallic acid as a comparison. The research results showed that the total tannin content in the ethanol extract was an average of 31.708mgQE/g.

Abstract

Antioxidants are compounds that can counteract free radicals in the body, reduce oxidation in cells and cell damage. The purpose of this study was to determine the antioxidant activity of ethanol extract of bitti leaves (Vitex cofassus Reinw. Ex. Blume with DPPH (2,2- diphenyl-1-picrylhydrazyl) scavenging method. The absorbance was measured by UV-Vis spectrophotometer at 510 nm wavelength. The results showed the presence of antioxidant activity with IC50 value of 56.59 μg/mL with strong antioxidant activity category, while quercetin as a comparator has very strong antioxidant activity with IC50 value of 5.93 μg/mL.

Abstract

MEDINA SALIM. Chemical Content Analysis and Determination of Lerak Leaf Polyphenol Content (Sapindus rarak DC) by UV-Vis Spectrophotometry Method (Guided by St. Maryam and A. Muflihunna). Lerak contains polyphenolic compounds that reduce blood sugar levels. This study aims to determine the chemical content contained in lerak leaf extract (Sapindus rarak DC) and find out how much polyphenol compounds in the sample. The samples were macerated for 3 days using 96% ethanol solvent, the extraction process was carried out until obtaining an extract yield of 9.323 grams, then two tests were carried out, namely qualitative and quantitative, The qualitative test uses a wet reagent while the quantitative test uses the UV-Vis spectrophotometry method. The maximum wavelength used was 768 nm with gallic acid as a comparison. Based on the study, the results of ethanol extract of lerak leaves (Sapindus rarak DC) contain secondary metabolites, namely saponins, steroids, polyphenols and tannins and the result of polyphenol content is 21,168 mgGAE/g.
