Abstract

Background: Numerous pharmaceutical applications for chitosan, a polysaccharide made from the shells of crustaceans by deacetylating chitin that occurs naturally, are currently being researched. Chitosan, a natural polymer, is successfully used to prepare many drug-carrier systems, such as gel, film, nanoparticle, and wound dressing.

Objective: Preparing chitosan gels without external crosslinkers is less toxic and environmentally friendly.

Methods: Chitosan-based gels containing Helichrysum pamphylicum P.H. Davis & Kupicha methanolic extract (HP) were produced successfully.

Results: The F9-HP coded gel prepared with high molecular weight chitosan was chosen as the optimum formulation in terms of pH and rheological properties. The amount of HP was found to be 98.83% ± 0.19 in the F9-HP coded formulation. The HP release from the F9-HP coded formula was determined to be slower and 9 hours prolonged release compared to pure HP. It was determined that HP release from F9-HP coded formulation with the DDSolver program was by anomalous (non-fickian) diffusion mechanism. The F9-HP coded formulation significantly showed DPPH free radical scavenger, ABTS•+ cation decolorizing and metal chelating antioxidant activity while weakly reducing antioxidant potential. According to the HET-CAM scores, strong anti-inflammatory activity was obtained by the F9-HP coded gel at a dose of 20 μg.embryo-1 (p<0.05 compared with SDS).

Conclusion: In conclusion, it can be said that chitosan-based gels containing HP, which can be used in both antioxidant and anti-inflammatory treatment, were successfully formulated and characterized.

Keywords: Antioxidant, chitosan gel, Helichrysum pamphylicum P.H. Davis & Kupicha, HET-CAM, polysaccharide, F9-HP.
