Citrus essential oil is the largest group among commercialized essential oils. Their unique sensory properties have been widely accepted and applied in beverage, confectionary, perfume, house care and other fields.  However, due to the simple chemical composition and tremendous price differences among citrus species, unscrupulous players have been practicing adulteration in citrus oils for a long time. Therefore industry is demanding definitive, sensitive, and efficient approaches to grade citrus oils. A reversed-phase HPLC method was developed for compositional study of major citrus oils. Majority of the oxygenated heterocyclic components in citrus oils were identified by HPLC-MS and confirmed by previous literatures. A comprehensive database of major polymethoxyflavone compounds is built with data collected from a large pool of industrial orange, tangerine and mandarin oil samples. Based on the numerical limits and statistical analysis results (PCA), detailed information regarding the history of oil samples can be revealed.
