  Cancer is recognized primarily as a disease of uncontrolled cell division. Hence, all efforts are directed toward the identification of antiproliferative compounds. Accordingly, regression of tumor size and increase of survival time has been recognized as the primary objective end point of effectiveness in preclinical and clinical testing for the discovery of a new anticancer drug. Dried roots from P. zeylanica were powdered and extracted with methanol. The root extract then at the dose of 20, 30 and 40 mg kg-1 day (i.p.) was evaluated for antiproliferative activity against Ehrlich Ascites Carcinoma (EAC) cells in swiss albino mice. The experimental parameters like tumor cell count, mean survival time and increase in life span were evaluated to assess antiproliferative activity. The extract was administered intrapretoneally for 14 consecutive days to EAC cell bearing group of mice. Bleomycin at the dose of 0.3 mg kg-1 (i.p.) was used as a positive control. It has been found that the root extract at the dose of 40 mg kg-1 day (i.p.) significantly (p<0.05) decreases tumor weight, increases life span and reduces tumor cell growth rate in comparison to those of EAC bearing mice receiving no extract (negative control) in a dose-dependant manner. In vitro antioxidant and cytotoxic activity of the same extract were also assessed to link the finding with the strong antiproliferative activity.
