Abstract

Two novel lanostane-type triterpene lactones, 3alpha, 11alpha-dihydroxy-7-oxolanosta-8,24-dien-26,23(R)-olide (1) and 1alpha,3alpha,11alpha-trihydroxy-7-oxolanosta-8,24-dien-26, 23(R)-olide (2), were isolated from the stem bark of Abies mariesii, together with a known triterpene, 3-oxo-9betaH-lanosta-7,24-dien-26, 23(R)-olide. The structures of 1 and 2 were determined on the basis of 2D NMR techniques.
