OBJECTIVE:To evaluate the anti-oxidant,enzyme inhibition,anti-pyretic,anti-inflammatory and anti-diabetic activities of Iris albicans.METHODS:Anti-oxidant assay was evaluated using DPPH(2,2-diphenyl-1-picrylhydrazyl)radical scavenging and ABTS(2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid)inhibitory protocol while enzyme inhibitory assay was evaluated by lipoxygenase and cyclooxygenase-2 inhibitory protocol respectively.Antipyretic,anti-inflammatory and anti-diabetic potential was evaluated using brewer's yeast induced pyrexia,carrageenan induced paw edema and streptozocin induced diabetes protocols respectively.Serum biochemical parameters were monitored for the period of study.RESULTS:The anti-oxidant activity of chloroform fraction of Iris albicans showed the highest scavenging potential against DPPH and ABTS while the maximum inhibitory action recorded against lipo-oxygenase and cyclooxygenase-2 enzymes was shown by n-hexane and chloroform fractions respectively.The anti-pyretic potential of the crude methanolic extract showed dose dependent activity in reducing pyrexia,thereby when the dose was increased the anti-pyretic effect was also enhanced.The anti-inflammatory action of the crude methanolic extract administered at the dose of 300 mg/kg was significant at 1 h after its administration,which was found maintained up to 5 h.Similarly the anti-diabetic effect of the crude methanolic extract administered at the dose of 200 and 300 mg/kg was noted highly significant at day 6 and was found well maintained throughout the study time period up to 10 days.Significant(P<0.001)improvement appeared in hemoglobin,protein,cholesterol,triglycerides,urea,creatinine,HDL and LDL of extract treated diabetic mice.CONCLUSION:From this data it could be concluded that Iris albicans have significant anti-oxidant,enzyme inhibition,ant-pyretic,anti-inflammatory and anti-diabetic potential.
