Enantiomeric distribution of α-pinene, β-pinene and limonene in essential oils and extracts. Part 2. Oils, perfumes and cosmetics

The enantiomers of α-pinene, β-pinene and limonene were directly determined in complex matrices by multidimensional gas chromatography using a non-chiral-chiral column combination. Essential oils, used for the preparation of perfumes and cosmetics, and commercially available perfumery products were analysed without sample clean-up. The enantiomeric distribution of the monoterpenes investigated allows a quality control of perfumes, a validation of essential oils as well as a differentiation of their natural or artificial origin.
