Penentuan Nilai Sun Protection Factor (SPF) Ekstrak Etanol Daun Jeruju (Acanthus Ilicifolius L.) secara In Vitro
Abstract
UV radiation can have an adverse effect on the skin. One of the ways to prevent these bad effects is to use sunscreen. The ethanol extract of jeruju leaves contains several secondary metabolites in the form of flavonoids and phenolics so that it has the potential as a sunscreen agent. This study aims to determine the activity of the extract as a sunscreen agent and to determine the SPF value of jeruju leaf extract. This research is an experimental laboratory with a quantitative approach. The SPF value of the ethanolic extract of jeruju leaves was determined by measuring the absorbance with several extract concentrations, 100, 200, 300, 400 and 500 ppm at the UV wavelength of 290-400 nm with 5 nm intervals using a UV spectrophotometer. The absorbance data obtained were analyzed using Microsoft Office Excel. The ethanol extract of jeruju leaves has activity as a sunscreen agent with the best SPF value indicated by a concentration of 500 ppm with a value of 3.8478 followed by a concentration of 400 ppm with a value of 2.9687, a concentration of 300 ppm with a value of 2.2672, a concentration of 200 ppm with a value of 1.7202 and a concentration of 100 ppm with a value of 1.3165.
