Two new tetranortriterpenoids were obtained by chromatography of the acetone extract of the wood of Spathelia sorbifolia L.; these compounds were characterized as their p-bromobenzoyl derivatives (2, 3). This extract also yielded a known tetranortriterpenoid and the chromones allopteroxylin, spatheliabischromene and anhydrosorbifolin
