Investigation of Hyaluronidase, Collagenase and Elastase Inhibitory Potentials and Comparative Evaluation of the Antimicrobial, Antioxidant and Homeostatic Activities of Two Natural Polysaccharides

Abstract

The aim of this study was to investigate the hyaluronidase, collagenase and elastase inhibitory effects, which play important role for wound healing, together with the antibacterial, antioxidant and homeostatic activities of tragacanth gum (TG) and locust bean gum (LBG). The antimicrobial activities were tested against four bacteria and the antioxidant activities were estimated by the 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydrogen peroxide (H2O2) radical scavenging and β-carotene bleaching assays. Homeostatic effect was evaluated with the Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) test parameters. The wound healing potentials were determined with the inhibition of hyaluronidase, collagenase and elastase enzymes. The TG showed antibacterial activity against Pseudomonas aeruginosa ATCC27853 and Escherichia coli ATCC25922. The results showed that TG and LBG possessed antioxidant properties including DPPH scavenging  (21.0% and 17.6%, respectively)  and H2O2 radical scavenging (59.4% and 79.0%, respectively) activities. The polysaccharides displayed significantly reducing PT and aPTT results. Between the two tested polysaccharides LBG showed significant hyaluronidase and collagenase inhibition activity at 10 mg/mL concentration. These findings show that these natural polysaccharides can be used to support of wound healing.
