Abstract:

Two compounds were isolated from the 75% EtOH extract of Boschniakia rossica Fedtsch et Flerov. The compounds were characterized as  β-D-glucopyranose 1-(3,7-dimethyl-2-trans-6-octadienoate) (1) and 6,7-dihydrofoliamenthoic acid diglucoside (2) by 1H and 13C NMR and 2D NMR techniques (i.e., 1H-1H COSY, HSQC, HMBC, and NOESY).  Compound 1 was found to be a new compound, while compound 2 was obtained from Orabanchaceae family for the first time.

Key words: NMR, assignment, β-D-glucopyranose 1-(3,7-dimethyl-2-trans-6-octadienoate), 6,7-dihydrofoliamenthoic acid diglucoside, monoterpene glycosides, Boschniakia rossica Fedtsch et Flerov
