Abstract
Two triterpenes 21R,23R-epoxy-21α-ethoxy-24S,25-dihydroxyapotirucall-7-en-3-one and 24R-acetoxy-3β,25-dihydroxycycloartane were isolated from the leaves of Dysoxylum malabaricum together with eight known compounds lupeone, lupeol, sitosterol, dipterocarpol, cycloart-25-ene-3β,24-diol, 24R,25-dihydroxycycloartan-3-one, 3β,24R,25-trihydroxycycloartane and ergosta-5,24(241)-diene-3β,4β,20S-triol. The complete 1H and 13C NMR spectral assignment of the new apotirucallene triterpenoid has been achieved by 1H–1H COSY, HMQC and HMBC experiments.
