Three new dammarane triterpenoids, gardaubryones A-C (1-3), were isolated from the gum collected on the aerial parts of Gardenia aubryi Vieill., together with the known compounds hydroxydammarenone II (4), ocotillone (5), cabraleone, and hollongdione. The structures of the novel compounds were established on the basis of mass spectrometry, NMR experiments, and chemical-correlation reactions. Copyright

From the unsaponifiable fraction of an ethereal extract of the leaves of Betula lanata, in addition to 3-epiocotillol (I) we have isolated a new triterpene, 20(S),24(R)-epoxydammarane-3α,11α,25-triol (V) and also derivatives of it - the monoacetates at C-3 (II) and C-11 (III), and the monoketone at C-3 (IV).The structures of compounds (I-V) have been established on the basis of the results of physicochemical investigations.
