Resumen :	Four lupane pentacyclic triterpenes were isolated from the hexane extract of stems and branches of Maytenus imbricata Mart.ex Reissek: 3-oxolup-20(30)-en-29-al (1), 30-hydroxylup-20(29)-en-3-one (2), (11α)-11-hydroxylup-20(29)-en-3-one (3), and (3β)-lup-20(30)-ene-3,29-diol (4). The structural identification of 1–4 was achieved by 1H- and 13C-NMR techniques, including 2D experiments (HSQC, HMBC, and NOESY).
