Evaluation of Anti-inflammatory Activity of Crinum scillifolium Extracts in Wistar Rats

Abstract

Aim of study: Inflammation was associated with many diseases in humans. Crinum species have a considerable medicinal reputation as potent folkloric remedies. The main objective of the study was to evaluate the anti-inflammatory activity of aqueous and hydroethanolic extracts of Crinum scillifolium bulbs in in vivo models. Materials and methods: The anti-inflammatory effect of Crinum scillifolium extracts was also evaluated in carrageenan-induced paw edema models and C-reactive protein (CRP) levels was measured. Two doses 100 and 200 mg/kg body weight for each extract, were tested. The results obtained were compared with those of the standard drug (Diclofenac at 25 mg/kg body weight) and those of the control (normal saline). Results: The results showed a highly significant decrease in the edema size (p < 0.01) and significant decrease in CRP values (p < 0.01) compared to control group when the animals were treated with diclofenac at 25 mg/kg, and 200 mg/kg of aqueous and hydroethanolic extracts. Conclusion: The study suggests that the extracts possess enough potential to reduce inflammation on rat model and directs the importance of further research and development of novel anti-inflammatory agents.
