Cupressuflavone a biflavone was ealier isolated from the leaves of Lophira lanceolata. From this work Betulinic acid was also isolate from the leaves for the first time. The two compounds were identified on the basis of 1D NMR (1H, 13C and DEPT), 2D NMR (COSY, HSQC, HMBC and NOESY), IR, MS data and by comparison with reported data. Like that of Ouretia this recent isolation suggest that betulinic acid can be used as chemical markers in the Ochnaceae family.
