ABSTRACT

This survey was designed to investigate the evaluation of synergic anticancer activity of Punica grantum L and Ziziphus mauritiana extracts by using invitro cytotoxicity assay, invitro and invivo antioxidant estimation. The invitro antioxidant activity of ethanol, aqueous and chloroform extracts of  Punica grantum L and Ziziphus mauritiana and combination of them was estimated by reducing power, diphenyl picryl hydrazyl scavenging and hydrogen peroxide scavenging assays using standard procedure, the invivo antioxidant activity was  also performed  by estimation of  Catalase and Glutathione in liver homogenate. The extracts were screened for their invitro cytotoxicity by trypan blue exclusion assay and Allium cepa root tips. The results displayed the 100µg/ml of both ethanol and aqueous extracts i.e. Punica grantum L and it’s combination with Ziziphus mauritiana having the maximum invitro antioxidant activity. Ethanol and aqueous extract of combination of Punica grantum L and Ziziphus and ethanol extract of Punica grantum L has produced the significant increase in the glutathione and catalase levels. The cytotoxic effect of ethanol extracts of Punica grantum L and Ziziphus mauritiana significantly increased in Ehrlich ascites tumour cells with an increase in concentration by trypan blue cytotoxic assay and also significant root growth inhibition in Allium cepa after 48h. The percentage decrease in mitotic index was found to be 27.28 % in 800 μg/ml of ethanol extracts of Punica grantum L and Ziziphus mauritiana. Accordingly, the synergic anticancer activity of illustrated extracts was evinced.

Key words: Antioxidant, cytotoxic assay, Punica grantum L, Zizipus mauritiana
