Two new monoterpenoid glycosides from Mentha spicata L.

Two new monoterpenoid glycosides, spicatoside A and spicatoside B, were isolated from the whole herbs of Mentha spicata L. which have anti-inflammatory and hemostatic activities. Their structures have been determined on the basis of spectral and chemical analysis. They are (+)-5-[1-(g -D-glucopyranosyloxymethyl)ethenyl]-2-methyl-2-cyclohexen-1-one (1), and (m )-5-{[2-( g -D-glucopyranosyloxy)-1-hydroxy-1-methyl]ethyl}-2-methyl-2-cyclohexen-1-one (2).
