Abstract
Enantioselective multidimensional GC using the column combination of a polyethylene glycol pre column and a chiral main column, coated with modified beta-cyclodextrins, allows the simultaneous stereodifferentia tion of important chiral compounds of the essential oil of Rosmarinus officinalis L. The enantiomeric ratios of alpha-pinene, camphene, beta -pinene, limonene, borneol, terpinen-4-ol, alpha-terpineol, (linalylac etate), linalol and camphor are investigated in authentic rosemary oil s and in commercially available oil samples of different origin. (1s-( -)-Borneol of high enantiomeric purity (ep >90%) has been detected as a reliable indicator of genuine rosemary oils. The addition of borneol as a synthetic racemate or as an alien essential oil (fraction) is co nclusively detected.
