FORMULASI SEDIAAN SERUM EKSTRAK ETANOL 96% DAUN TEKELAN (Chromolaena odorata (L) R.M. King & H. Rob) DAN UJI ANTIOKSIDAN [FORMULATION OF 96% ETHANOL EXTRACT SERUM PREPARATION OF TEKELAN LEAVES (Chromolaena odorata (L) R.M. King & H. Rob) AND ANTIOXIDANT TEST]

Tekelan leaves are known to have antioxidant activity therefore they can be developed into cosmetic products. The objective of this study was to develop a serum formulation from tekelan leaves extract and antioxidant test. Tekelan leaves extract was prepared by maceration with 96% ethanol. The 96% ethanol extract of tekelan leaves extract was made into 3 formulations with a variety of emollient ingredients, namely squalene, dimethicone and almond oil. Evaluation carried out on serum preparations included organoleptic, homogeneity, pH, viscosity, specific gravity, adhesion and stability tests. The extract yield was 25.40%. Testing for phytochemical content showed that the extract contained alkaloids, flavanoids, phenols, tannins, saponins and steroids. Evaluation results of the three serum formulas meet physical quality test requirement such as organoleptic, homogenity, pH, specific weight and viscosity but did not meet the adhesion test requirements. In addition, all three serum formulas showed very weak antioxidant activity.
