Abstract

Excessive exposure to sunlight can cause the formation of free radicals that can damage skin tissue, thus requiring natural antioxidants. The use of natural ingredients as a source of antioxidants in the form of topical preparations is a potential alternative. This study aims to formulate ethanol extract of yakon leaves (Smallanthus sonchifolius) into a face toner formulation and evaluate its physical quality, antioxidant activity, and to determine the optimal concentration of the face toner formulation that can inhibit free radicals. Extraction was carried out using the maceration method with 70% ethanol, then formulated into face toner with different concentrations, namely 1%, 2%, and 3%. After that, physical quality evaluation was carried out in the form of organoleptic tests, pH tests, homogeneity tests, and viscosity tests. Antioxidant activity was tested using the DPPH method and measured using UV-Vis spectroscopy at a wavelength of 520 nm. The results showed that all formulas met the physical quality test standards and had antioxidant activity at concentrations of 1%, 2%, and 3% with IC50 values of 95.91, 93.58, and 91.70, respectively, all of which were classified as strong. while the negative control formula without extract had a value of 167 (weak category), and the positive control quercetin had a value of 9.95 (very strong category).

Abstract

ABSTRACT Indonesia has high levels of ultraviolet (UV) exposure, which poses a risk of skin health problems. The use of sunscreen is necessary as a protective measure, but synthetic sunscreens can cause side effects, so natural alternatives are needed. Green amaranth leaves (Amaranthus hybridus L.) contain flavonoids that have the potential to absorb UV rays. This study aims to evaluate the sunscreen activity of green amaranth leaf extract using 70% ethanol and acetone solvents, determine the optimum Sun Protection Factor (SPF) value, and identify the most effective and efficient solvent. Extraction was performed using the maceration method, then the sunscreen activity was tested using UV-Vis spectrophotometry at a wavelength of 290–320 nm with concentration variations of 40, 60, 80, 100, and 120 ppm. The results showed that both extracts had sunscreen activity. The optimum SPF value was obtained at a concentration of 120 ppm, namely 70% ethanol extract 11,45 (maximum protection) and acetone extract 19,11 (ultra protection). Acetone was the most effective and efficient solvent in extracting UV-absorbing compounds. Keywords: 70% Ethanol, Acetone, Green Spinach Leaves (Amaranthus hybridus L.), SPF, Sunscreen
