Objective:To explore cytotoxic activity of ethanol extract of Alpinia calcarata Rose(EEAC) rhizome against Ehiiich ascites carcinoma(EAC) tumor bearing Swiss Albino mice.Methods: In the present study,its anti-neoplastic activity has been studied by monitoring parameters like tumor weight measurement,survival time,tumor cell growth inhibition,haematological characteristics etc.Results:It was found that EEAC at dose 8 mg/kg/day(i.p.) significantly decreased tumor weight(62.0%;P0.01),increased life span(70.25%;P 0.01) and reduced tumor cell growth rate(85.7%;P0.01) in comparison to those of EAC bearing mice.The plant extract also improved the depleted haematological parameters like RBC WBC,Hb%,differential counts(e.g.lymphocytes,neutrophils,monocytes etc) of EAC bearing mice towards normal.The host toxic effects were not very high and recovered gradually towards normal within a few days after treatment.ConchiskHis:EEAC exhibits potent in vivo cytotoxic activity against EAC tumor bearing Swiss Albino mice.So,the plant can be considered as a probable new source of antitumor agents.
