Monoterpenoids and their glycosides from the leaf of thyme.

From the polar portion of the methanol extract of thyme (leaf of Thymus vulgaris; Labiatae), which has been used as an important stomachic, carminative, a component of prepared cough tea, and a spice, seven monoterpenoid glycosides were isolated together with two known monoterpenoids and three known monoterpenoid glucosides. Structures of the seven monoterpenoid glycosides were determined by spectral analysis.
