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.
