Authenticity Analysis of Cold-Pressed Orange Essential Oils by GC/MS on Polymethoxyflavone Components

Citrus essential oil combines numerous components with many qualities and control issues. For example, how to monitor volatile nonvolatile substances simultaneously is a major problem. Therefore, the objective of this study was develop Gas chromatography/mass spectrometry (GC/MS) method for compositional total constituents in cold-pressed oils from orange species. A polysiloxane GC column (DB-1, nonpolar, low-bleeding) used study; its fingerprint includes terpenoids (Section 1), long-chain hydrocarbons 2), phytosterols, polymethoxyflavones 3). These markers are more effective detecting adulteration products than components, quantitative PMF by 5α-Cholestane establishing authenticity. The aims use analysis procedure as routine quality test authenticity evaluation (CP-OrEO).
