Abstract:
Two new monocyclic monoterpenoid glycosides, rel-(1R,2S,3R,4R) p-menthane-1,2,3-triol 3-O-β-D-glucopyranoside (1) and rel- (1S,2R,3S) terpinolene-1,2,3-triol 3-O-β-D-glucopyranoside (2) were isolated from aqueous acetone extract of the aerial parts of Mentha haplocalyx Briq.. Their structures were elucidated through spectral analysis using MS and NMR spectrometers.
