Evaluation of Free Radical Scavenging, Anti-inflammatory and Analgesic Potential of Benincasa hispida Seed Extract

N.S. Gill, K. Dhiman, J. Bajwa, P. Sharma and S. Sood
The present study was designed to investigate the free radical scavenging, anti-inflammatory and analgesic potential of methanolic extract of Benincasa hispida seeds (MEBH). Free radical scavenging potential of MEBH was evaluated by DPPH (1,1-diphenyl-2-picryl-hydrazyl) and hydrogen peroxide (H2O2) method. The extract showed significant free radical scavenging activity in a dose dependent manner when compared with ascorbic acid. The highest radical scavenging activity of MEBH was found to be 79.8% at concentration of 300 μg mL-1. The H2O2 scavenging effect of MEBH was 63.7% at a concentration of 200 (μg mL-1). Further, the extract was studied for its anti-inflammatory and analgesic activities at the dose level of 100, 200 and 300 mg kg-1. Anti-inflammatory activity was evaluated using carrageenan-induced paw edema in rats. Analgesic activity was evaluated by tail immersion and tail flick methods in mice. The extract showed significant decrease in paw volume (59.7% reduction) and pain at the dose level of 300 mg kg-1 when compared with reference drug diclofenac and morphine, respectively. The MEBH may be useful as a natural antioxidant in the treatment of inflammation and pain.
