The crude extracts from Rhus javanica Linne showed comparatively strong antioxidative activity in test oils. Antioxidative components were isolated and identified by column chromatography, thin layer chromatography, UV, and NMR. These antioxidative components were added to several oils to compare antioxidative activity with several commercial antioxidants, such as BHA, BHT, and tocopherol. After the sixth column chromatography, one fraction (R-18-9-3-2-4-2) was separated from chloroform layer of Rhus javanica Linne. The R-18-9-3-2-4-2 fraction was identified as methyl gallate by $^1H-NMR$ and $^{13}C-NMR$ and confirmed with methyl gallate standard as authentic. The R18-9-3-2-4-2 fraction from chloroform layer of Rhus javanica Linne showed stronger activity than that of the ${\alpha}-,\;{\delta}-tocopherol$, BHT, and BHA at the same concentration.
