Aerial parts of Villarsia exaltata (Menyanthaceae) were investigated for secoiridoids. Two new acylated compounds of the “foliamenthintype”, named exaltoside and 7-epiexaltoside, have been isolated and structurally elucidated by spectroscopic means (1H-, 13C-NMR, COSY, FAB and FD mass spectrometry).
Villarsia exaltata - Menyanthaceae - secoiridoid glucosides - dimeric monoterpenes - exaltoside - 7-epiexaltoside - secologanic acid - episecologanic acid - 8-hydroxy-2,6-dimethyl-2(E),6(E)-octadienoic acid
