title: Tumor inhibitory agents from Vauquelinia corymbosa (Rosaceae).
abstract: The chloroform extract of Vauquelinia corymbosa Correa has shown activity against the P-388 lymphocytic leukemia test system. The constituents responsible for this activity were identified as uvaol, ursolic acid, and betulinic acid. Their identity was proven by melting point; mixed melting point; elemental analysis; IR, PMR, and mass spectra; and preparation of derivatives.
