Abstract:
:Five tirucallane-type triterpenes were isolated along with nine known triterpenes from the bark of Juliania adstringens. The structures of the five triterpenes were determined by analysis of their 1H and 13C NMR and mass spectral data, and each compound exhibited growth inhibitory activity against leukemia cells (L-1210).
