A Synchronous Fluorescence Spectrofluorometric Method For The Simultaneous Determination Of Policresulen And Cinchocaine Hydrochloride In Ointment And Suppositories

For the treatment of internal and external hemorrhoids, policresulen (POL) and cinchocaine hydrochloride (CIN) are used in combination. Using a new, simple, fast, and economical first-derivative synchronous fluorescence spectroscopic process, both drugs were simultaneously determined and validated. At Delta lambda 60 nm and with a scanning rate of 600 nm/min, methanol was used as the solvent for both products. In the concentration ranges of 5.0-21.0 mu g mL(-1) and 0.5-6.0 mu g mL(-1) for POL and CIN, the amplitude-concentration plots were rectilinear. The detection limits were found to be 0.770 mu g mL(-1) and 0.118 mu g mL(-1) and the quantitation limits for POL and CIN were 2.541 mu g mL(-1) and 0.391 mu g mL(-1). To evaluate all compounds in synthetic mixtures and medicinal dosage types, the proposed method has been successfully applied. These findings were in line with the results obtained using high-performance thin layer chromatography, the comparison process. (C) 2021 Elsevier B.V. All rights reserved.
