Three new triterpenoids, 2,3-seco-3-oxours-12-en-2-oic acid, 2,3-seco-3-oxoolean-12-en-2-oic acid, and betulin 3-O-palmitate, have been isolated from the rhizomes and roots of Gentiana lutea, together with five known ones. The structures of the new compounds were determined by spectral and chemical methods.
