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.

Crinum species is frequently used for the treatment of nervous disorders such as epilepsy. This study aimed to investigate the anticonvulsant activity of the hydroethanolic extract of the Crinum scillifolium bulbs in chemoconvulsant-induced seizures in mice. The anticonvulsant activity of the extract (25, 50, 100, 200 and 400mg/kg), was investigated in isoniazid (INH)-induced seizures in mice. The hydroethanolic extract protected mice from INH-induced seizures in a dose-dependent manner. 100% of protection was observed when the animals were treated with 200 and 400mg/kg of hydroethanolic extract of Crinum scillifolium. At Dose of 50 and 100mg/kg 83% protection was observed; the onset of convulsion significant was delayed, and no mortality was found of the mice against isoniazid-induced convulsion. Mice pretreated with hydroethanolic extract at the dose of 25mg/kg reduced mortality to 27% and significant delayed the onset of death (p<0.01). In conclusion, Crinum scillifolium was revealed possessing anticonvulsant effects in mice, via the GABAergic neurotransmission.
