摘要

In Indonesia, beras ( Oryza sativa ) has become the main ingredient in natural beauty products such as masks, scrubs, and cold powder. γ-oryzanol and phenolic compounds are the major components in beras that have many benefits, one of which as antioxidants. This study aims to determine the content of γ-oryzanol and total phenolic compounds in different beras cultivars in the area of Yogyakarta. The leveling was done by a TLC-densitometry method and Folin Ciocalteu. The results showed that the largest γ-oryzanol content found in red beras was 0.0843% by weight of the sample. The highest total phenolic content was found in red beras as much as 1.92% by weight of the sample. The antioxidants activity IC_(50) Red Beras is 0.591.
