Study of anti-inflammatory activity of Ficus racemosa linn stem bark extract in albino rats

Priya Mohan B. N., Suma Jayaram, Sanitha Kuriachan


Background: Inflammation is part of the complex biological response of vascular tissues to harmful stimuli. Though there are standard anti-inflammatory drugs like aspirin, diclofenac, etc., these are not free of side effects. This has led to an increase in demand for natural products with anti-inflammatory activity having less side effects. Hence the study was conducted to evaluate the anti-inflammatory activity of ethanolic extract of Ficus racemose (EEFR) in albino rats.

Methods: Healthy albino rats of either sex were divided into 4 groups of 6 animals each. Group1-control, group 2-diclofenac sodium 2 mg/kg and group 3 and 4 EEFR (200 and 400 mg/kg respectively), anti-inflammatory activity was evaluated by Carrageenan induced paw oedema: formalin induced-peritonitis and cotton pellet induced granuloma model for in vivo activity and protein denaturation test for in vitro activity.

Results: EEFR exhibited significant in vitro (p<0.001) anti-inflammatory effect at the dose of 200 and 400 mg/kg. EEFR produced 61.37% inhibition at the dose of 400 mg/kg and diclofenac (standard drug) produced 62.95% of inhibition after 3 hours of drug treatment in carrageenan induced paw oedema. The exudate volume was decreased in formalin induced peritonitis by EEFR and diclofenac significantly (p<0.001). In cotton pellet induced granuloma EEFR (400 mg/kg) and diclofenac showed decreased formation of granuloma by 28.36% and 28.00% (p<0.001) respectively.

Conclusions: EEFR has significant anti-inflammatory activity in both acute and chronic model in a dose dependant manner in comparison with standard drug.
