Abstract

Antioxidants have many different benefits in the body, including inhibiting the oxidation process. Antioxidants are found in several plants, including black sticky rice (Oryza sativa var glutinosa). Color pigment in black sticky rice contains a mixture of anthocyanin compounds that function as antioxidants and free radical scavengers. This study aims to describe the antioxidant activity of black glutinous rice extract with extraction for different hours and solvents. Research design is a literature study or a review of scientific articles. The antioxidant activity was tested using the DPPH method so that it could be applied as an innovative liquid soap with organic ingredients. The results obtained were that the stability of anthocyanins was influenced by pH, temperature, and extraction time, acetone solvent had a greater amount of anthocyanin extract than ethanol. Anthocyanins can be applied because they contain phenolic compounds in anthocyanins which can inhibit bacterial growth, marked by an inhibition zone.

KEYWORDS: antioxidants, black glutinous rice, soap, anthocyanin.
