Antitumour Activity of Methanolic Extract of Plumeria alba L. Leaves against Dalton Lymphoma Ascites in Mice

ABSTRACT

Purpose: To evaluate Plumeria alba leaves for antitumor activity against Ehrlich ascites carcinoma (EAC) and Dalton lymphoma ascites (DLA) bearing Swiss albino mice. Method: The antitumour activity of the methanolic extract of Plumeria alba leaves (MPA) was evaluated against EAC and DLA using in-vitro cytotoxic and mean survival time; a decrease in the tumour volume and viable cell count in the DLA tumour hosts. The animal was observed for improvement in the haematological parameters (e.g.; heamoglobin content; red and white blood cells count; and differential cell count) following MPA treatment of the tumour bearing mice. Results: MPA was found to be cytotoxic in the in-vitro model. Intraperitoneal administration of MPA increased the survival time; dead cell count haematological parameters and solid tumour mass was also significantly reduced. Conclusion: MPA possesses significant antitumour activity
