title: Monoterpene glucosides from Origanum syriacum.
abstract: From the aerial parts of Origanum syriacum, three new monoterpene glucosides thymoquinol 2,5-O-beta-diglucopyranoside (3), carvacrol 2-O-beta-glucopyranosyl-(1-->2)-beta-glucopyranoside (4) and p-menth-1-ene-3,4-diol 4-O-beta-glucopyranoside (5) together with two known monoterpene glucosides thymoquinol 2-O-beta-glucopyranoside (1), thymoquinol 5-O-beta-glucopyranoside (2) have been isolated. The structures of the isolated compounds were verified by means of MS and NMR spectral analyses.
