Authenticity Control of Alpine Aromatic Plants by Enantioselective Gas Chromatography–Mass Spectrometry. Part 1: White genepi (Artemisia umbelliformis Lam.)

FH - HES

Abstract

A method for the authenticity control of the alpine aromatic plant white genepi (Artemisia umbelliformis Lam.) was developed by means of coupling headspace solid-phase microextraction with enantioselective GC–MS. By using heptakis[2,3-di-O-methyl-6-O-tert.-butyldimethylsilyl)-?-cyclodexrin as stationary phase the chiral monoterpenes borneol, ?-pinene, ?-pinene, and ?-terpineol could be analyzed simultaneously allowing their enantiomeric ratios to be used as reliable indicators of genuine white genepi plant material.
