Description
Summary:Objective: Hyaluronic acid (HA) is a naturally occurring, biocompatible polysaccharide with unique viscoelastic and hygroscopic properties. Its role as a natural lubricant and its excellent water-retaining properties make it well-suited for use in ophthalmic products. The objective of this study is determination of sodium hyaluronate in ophthalmic solution liquid chromatography (HPLC) method with UV detection and, stability of the product. Methods: The analysis was carried out using a polymer column (PolySep-GFC- P5000) with a mobile phase consisting of (dH2O: 20 mM Phosphate Buffer pH:6.5), (95:5, v:v) at a flow rate of 1.2 mL/min. UV detection was set 205 nm. Results: Calibration curve was linear over the concentration range of 80%-120% concentration of the ophthalmic product. The back calculated concentrations of the calibration standards were within ±15% of the nominal value (±20% for LOQ). The stability of ophtalmic solution was found to be 92.5% at the end of the days at room tempereture. Conclusion: The developed method is fast and reliable for HA analysis in ophthalmic products. Accordingt to stability study, these products must be stored at +4 C during usage and storage.
