Supercritical CO2 (SC-CO2) was used to extract dabai oil. Total phenolic content, total flavonoid content, DPPH radical scavenging assay, and gas chromatography analysis were performed to determine the antioxidant properties of SC-CO2-extracted dabai oil and to compare with hexane-extracted dabai oil. The total phenolic content of SC-CO2-extracted oil was slightly higher than hexane-extracted oil, whereas the total flavonoid content of SC-CO2-extracted dabai oil was four times lower than the hexane-extracted oil. The percentage of radical scavenging activity for SC-CO2-extracted oil was 0.71%, but the hexane-extracted oil had a higher radical scavenging activity of 3%. Analysed using gas chromatography, SC-CO2-extracted oil had lower total saturated fatty acids than the hexane-extracted oil. © 2017 Science Society of Thailand under Royal Patronage.
