| Abstract: | The present study evaluated the topical anti‐inflammatory potential of a standardized pomegranate rind extracts (SPRE) in parallel with its marker compound ellagic acid (EA, 13% w/w) against a mouse model of contact dermatitis. In the phenol‐induced mouse ear edema, topical application of SPRE (5, 2.5, and 1 mg/ear) and EA (0.65, 0.325, and 0.13 mg/ear, equivalent to its content in SPRE) dose‐dependently reduced the ear edema with the maximal inhibition of 79.12% and 73.63%, respectively. Triamcinolone (0.1 mg/ear) and diclofenac (1 mg/ear) as reference drugs inhibited the edema by 73.63% and 37.91%. Myeloperoxidase (MPO) activity in the mouse ear was also decreased by SPRE and EA up to 69.68% and 68.79%, respectively. Triamcinolone and diclofenac decreased the MPO activity by 76.66% and 80.14% similarly. The results indicated that topical application of SPRE and EA is promising for use in the treatment of inflammatory skin disorders. Copyright © 2013 John Wiley & Sons, Ltd. |
