Thymol (1) and Carvacrol (2) are monoterpenoid natural products that display in vitro antimicrobial activity against Campylobacter jejuni and coli, food-borne pathogens found in animal distal guts/avian crops that commonly contaminate meat and poultry dur

Naturally occurring glucosides of benzyl alcohol, (±)-menthol, (+)-borneol, thymol, carvacrol and eugenol were synthesized by the Koenigs-Knorr-Zemplen method (yields 19.5-52.2 %). Their β-D-glucopyranosidic structures were determined by one- and two-dimensional homo-and heteronuclear 1H and 13C NMR spectroscopy. The β-configuration was additionally confirmed by the hydrolysis with β-glucosidase. Tetraacetyl-β-D-glucopyranosides, as intermediates, were GC-MS analyzed. Diastereomeric β-glucoside tetraacetates of (±)-menthol were well separated on the HP-101 column. The mass spectra of glucopyranoside tetraacetates were mutually compared, as well as with the spectra of their aglycones.

Ten new hemi- and monoterpenyl β-D-glucopyranosides have been prepared by a modification of the Koenigs-Knorr procedure which utilises silver fluoroacetate as a soluble catalyst coupled with the introduction of a basic ion-exchange resin to effect the deacetylation step.Most of these compounds could not be obtained in acceptable yields using the classical procedure.
