【 摘 要 】

Punica granatum L., a plant widely used in Brazil, was tested for its antitumor and antiangiogenic activities in vitroand in vivo. In this work, the in vitrocytotoxicity was evaluated using the K-562 cell line and Ehrlich ascites tumour cells, by MTT tetrazolium reduction test and the trypan blue exclusion test. In vivostudies investigated the increase in the survival time of Ehrlich tumour-bearing mice after treatment with different doses of Punica granatumL. ethanol extract (12.5; 25; 50 e and 100 mg/kg), by gavages, for ten consecutive days. In addition, we also investigated the tumour inhibition potential and antiangiogenic activity of this plant. In vitroresults demonstrated a decrease of K-562 and Ehrlich ascites tumour cells viability, with both methods used, in a dependent-manner concentration. In vivoresults showed a significant antitumor activity against Ehrlich ascites tumour growth, increasing survival time. In parallel, we detected a significant inhibition of the tumour growth, along with a decrease in the vascular pattern of the peritoneal wall. Thus, the data presented herein clearly showed that Punica granatum L. has antitumor and antiangiogenic activities.
