type: AcademicArticle

abstract: Bioactive compounds such as tocopherols, tocotrienols, and gamma oryzanol are contained in rice bran, which is a byproduct of the rice milling process. Gamma oryzanol in bran has high antioxidant activity, hence it can ward off free radicals. Previous studies have shown this antioxidant activity with an value of 0.591. This study aims to determine the antioxidant activity of various concentrations of ethanol extract of 96% brown rice bran in an emulgel preparation. The brown rice bran was extracted by maceration method using 96% ethanol solvent. Furthermore, it was made in an emulgel preparation with 3 variations in concentration, namely 0.591 (F2); 1 (F3); 1.5 (F4). Determination of antioxidant activity was carried out by the DPPH method and compared with emulgel without extract (F1). The results obtained showed that the F4 extract 1.5% had better activity than the other preparations with an value of 108.3224 µg/mL and AAI 1.4561. Therefore, it can be concluded that the 96% ethanol extract emulgel preparation of brown rice bran has moderate antioxidant activity and its AAI value range falls into the range of strong antioxidant activity.
