AIMS AND OBJECTIVES: The purpose of this study was to evaluate and compare the anti-inflammatory activity of the aqueous root bark extract of Aegle marmelos (Bilwa) in experimental acute and chronic inflammatory animal models.
MATERIALS AND METHODS: Aqueous extract of root bark of Bilwa was prepared and tested for anti-inflammatory activity in albino rats weighing 150-280 grams. The animals were randomly divided into 3 groups of 6 each; one group served as control and other two groups received indomethacin and Bilwa orally 1 hour prior to experimentation. The in vivo anti-inflammatory activity was studied using the acute (Carrageenan induced paw edema) and chronic (Cotton pellet induced granuloma) animal models. Anti-inflammatory activity was expressed as Percent inhibition (PI). Statistical analysis was performed using One-way analysis of variance (ANOVA) followed by Scheffe's post hoc test. P<0.05 was considered statistically significant.
RESULTS: The PI with indomethacin and Bilwa in carrageenan induced paw edema were 52.7% and 46% and in cotton pellet induced granuloma were 24.7% and 9.2% respectively. Indomethacin showed highly significant anti-inflammatory activity in both the models. However, Bilwa showed highly significant activity in acute model and but a trend of anti-inflammatory activity in chronic model studied.
CONCLUSIONS: As Bilwa showed significant anti-inflammatory activity in the models studied, it can be a promising anti-inflammatory agent.
