Identification of Essential Oils From The Bark of Balik Angin (Alphitonia Incana (Roxb.) Teijsm. & Binn. Ex Kurz)

One of the components that make up essential oils is phenolic compounds which are widely containedin leaves and bark Balik Angin plant (Alphitonia incana (Roxb.) Teijsm. & Binn. ex Kurz).This study aimed to identify antioxidant activity from thebark plant. The isolation using hydrodistillation compoundswere analyzed gas chromatography-mass spectroscopy (GC-MS). Qualitatively antioxidantactivity test used thin layer chromatography (TLC) quantitatively by measuring absorbance of2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals residue did not react against reducer.The results showed contain major methyl salicylate followedby palmitate, 2,2-Dimethyl-1,3-dioxane-4,6-dione, 12-acetoxyoleate. Qualitativetest with TLC there were four yellow spots on a purple background. Thescavenging had an IC50 229.056 ppm, while gallic acid as acomparative standard obtained 0.618 ppm. conclusion BalikAngin produces very weak activity.
