Abstract:

Mirabilis Jalapa Linn. is a widely used traditional medicine in many parts of the world for the treatment of various diseases viz. virus inhibitory activity, anti tumour activity. It is claimed in traditional medicine that the leaves of the plant are used in the treatment of inflammation. In the present study, the total alcoholic extract and successive petroleum ether fractions of leaves of Mirabilis Jalapa Linn were screened for its anti-inflammatory activity using carageenan induced rat paw edema and cotton pellet induced granuloma models. The total alcoholic extract at the dose of 300mg/kg p.o and successive petroleum ether fraction at the dose of 200mg/kg exhibited significant anti-inflammatory activity in carrageenan induced paw edema model (p<0.01). In cotton pellet granuloma model, the total alcoholic extract at the dose of 300 mg/kg and successive petroleum ether fraction at the dose of 200mg/kg inhibited granuloma formation significantly (p<0.05) indicating that both test samples inhibit the increase in number of fibroblasts and synthesis of collagen and mucopolysaccharides during granuloma tissue formation during the chronic inflammation. These experimental results have established a pharmacological evidence for the folklore claim of the drug to be used as an anti inflammatory agent
