Characterization of Arachis hypogaea L. oil obtained from different extraction techniques and in vitro antioxidant potential of supercritical fluid extraction extract

摘要: Aim: The present investigation was aimed to characterize the fixed oil of Arachis hypogaea L. using five different extraction methods: Supercritical fluid (SFE), ultrasound assistance extraction, soxhlet solvent and three phase partitioning method. Materials Methods: SFE conditions (temperature, pressure, volume CO 2) were optimized prior for better yield. extracted oils analyzed compared their physiochemical parameters, high-performance thin layer chromatography (HPTLC), gas chromatography-mass spectrometry (GC-MS), Fourier transform infrared (FT-IR) fingerprinting. Anti-oxidant activity also determined DPPH superoxide scavenging Results: main fatty acids oleic, linoleic, palmitic, stearic as obtained by GC-MS. HPTLC analysis revealed presence similar major components in chromatograms. Similarly, pattern peaks FT-IR GC-MS spectra same methods superimposable. Conclusion: Analysis reported that A. is a good source unsaturated acid, mainly n-6 n-9 acid with significant antioxidant from
