ResumoThe leaves and stem of Desfontainia spinosa were found to contain eleven urs-12-ene triterpene compounds. The major compound present was ursolic acid. Four other known compounds were isolated, i.e. ursolic acid acetate, pomolic acid, 23-hydroxytormentic acid and nigaichigoside Fl, its ester glucoside. The other six compounds are novel and have been identified as 24-hydroxytormentic acid, 7α-hydroxytormentic acid, 7α,23-dihydroxytormentic acid and their corresponding ester glucosides. It is unlikely that these compounds contribute to the reputed narcotic properties of this plant.
