Description:
One of the components that make up essential oils is phenolic compounds which are widely contained in the leaves and bark of the Balik Angin plant (Alphitonia incana (Roxb.) Teijsm. & Binn. ex Kurz). This study aimed to identify phenolic compounds and antioxidant activity of essential oils from the bark of the Balik Angin plant. The essential oils isolation using hydrodistillation and the compounds were analyzed using gas chromatography-mass spectroscopy (GC-MS). Qualitatively antioxidant activity test used thin layer chromatography (TLC) and quantitatively by measuring the absorbance of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals residue that did not react against compounds reducer. The results showed the essential oils contain major compounds which are methyl salicylate followed by methyl palmitate, 2,2-Dimethyl-1,3-dioxane-4,6-dione, and methyl 12-acetoxyoleate. Qualitative test results of antioxidant activity with TLC there were four yellow spots on a purple background. The scavenging activity showed the essential oils had an IC50 of 229.056 ppm, while the gallic acid as a comparative standard obtained an IC50 of 0.618 ppm. The conclusion is the essential oils of Balik Angin bark that produces very weak antioxidant activity.
