Abstract

One of the components that make up essential oils is phenolic compounds which are widely containedin 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 thebark of the Balik Angin plant. The essential oils isolation using hydrodistillation and the compoundswere analyzed using gas chromatography-mass spectroscopy (GC-MS). Qualitatively antioxidantactivity test used thin layer chromatography (TLC) and quantitatively by measuring the absorbance of2,2-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 followedby methyl palmitate, 2,2-Dimethyl-1,3-dioxane-4,6-dione, and methyl 12-acetoxyoleate. Qualitativetest results of antioxidant activity with TLC there were four yellow spots on a purple background. Thescavenging activity showed the essential oils had an IC50 of 229.056 ppm, while the gallic acid as acomparative standard obtained an IC50 of 0.618 ppm. The conclusion is the essential oils of BalikAngin bark that produces very weak antioxidant activity.

Abstract

Alphitonia incana (Roxb.) Teijsm. & Binn. ex Kurz locally known as Balik Angin in Borneo Island is one of the endemic plants that have the potential to be an alternative antibacterial agent. Balik Angin leaves contain secondary metabolites that have to play a role to inhibit the growth of Gram-positive bacteria. This study aimed to compare the different extraction solvents which are methanol and ethanol on the maceration of Balik Angin leaves in producing antibacterial activity against Propionibacterium acnes. The leaves were macerated using methanol and ethanol respectively. Antibacterial assay was carried out by the Well diffusion method. The results showed minimum inhibitory concentration (MIC) of ethanol extract which is 3.2% has a diameter of clear zone of 9.475±0.311 mm. Meanwhile, the methanolic extract with a similar MIC has a lower diameter of clear zone of 2.55±0.85 mm. The results correlate with the number of secondary metabolites groups that were identified based on phytochemical screening in ethanol extract containing alkaloid, phenolic, flavonoid, tannin, saponin, and phytosteroid, however, methanol extract not containing alkaloid. The conclusion of this study is ethanol solvent more effective to extract secondary metabolites from Balik Angin leaves compare to methanol solvent, so that can produce more powerful anti-Propionibacterium acnes activity.
