Abstract
Virgin coconut oil was used as green solvent for the extraction of total phenolics from I. herbstii (I. herbstii: coconut oil, 1:10 (w/w)). I. herbstii extract-containing coconut oil (ECC) had dark red in color. Acid value (AV), peroxide value (PV), thiobarbituric acid-reactive substances (TBARS), ρ-anisidine value and volatile compounds were taken as parameters for evaluation of oxidative stability of EEC sample. All parameters of EEC sample were lowered, in comparison with the control sample during storage for 7 weeks. ECC sample produced less TBARS value than the control (p<0.05). Abundance of volatile compounds in all samples correlated well with the TBARS value. Results revealed the use of coconut oil as green solvent for extraction of bioactive compounds and natural red pigment from I. herbstii, where I. herbstii as antioxidant to prevent lipid oxidation in vegetable oil.
