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.
