Chiral Compounds of Essential Oils. XX. Chirality Evaluation and Authenticity Profiles of Neroli and Petitgrain Oils

Abstract
The simultaneous stereochemical analysis of the main compounds linalool, linalyl acetate, α-terpineol using heptakis-(2,3-di-O-acetyl-6-O-tert.-butyldimethyl-silyl)-β-cyclodextrin as the chiral main column is described. α-Pinene, β-pinene, limonene, terpinen-4-ol and nerolidol are simultaneously stereoanalyzed with heptakis-(2,3-di-0-methyl-6-O-tert.-butyldimethylsilyl)-β-cyclodextrin. Chirality evaluation was proved to be an efficient tool for the authenticity control of neroli and petitgrain oils. Characteristic authenticity profiles of neroli and petitgrain oils are deduced.
