Quantification of doxycycline hyclate in different pharmaceutical samples by UV assay
Journal Title: European Journal of Biological Research - Year 2016, Vol 6, Issue 4
Abstract
A simple, selective, linear, precise and accurate ultraviolet detection (UV) method has been developed and applied for the determination of doxycycline hyclate in different pharmaceutical samples. A mixture of methanol and hydrochloric acid (0.01N Methanolic HCl) was used to determine the biochemical properties of doxycycline hyclate. UV detector set at 349 nm was used to monitor the effluent. The purified water was used as solvent. The method proved to be linear (R2=0.993), precise (RSD=0.79% for inter-day precision), accurate (Recovery=100.59%) and selective regarding possible impurities and excipients of the samples. The doxycycline content obtained in the sample analysis was within the range of 84.05% to 85.80%. The optimized and validated method may be successfully employed to perform routine quality control analyses. Investigation of the pH, moisture content and potency of doxycycline hyclate in different samples give a general view of local pharmacies trade and ensure that the method applied here was validated for this kind of analysis.
