      Reversed-phase high-performance liquid chromatography and high-performance thin-layer liquid chromatography methods for simultaneous determination of theophylline, guaifenesin and guaifenesin impurity (guaiacol) in their bulk powders and in dosage form
      E.A. ABDELALEEM, I.A. NAGUIB, S.A. FARAG*, H.E. ZAAZAA (*Anal. Chem. Dep., Faculty of Pharm., Nahda Univ., Beni-Suef, Egypt, shosho_5005eg@yahoo.com)

      J. Chromatogr. Sci., 56 (9), 846–852 (2018). Simultaneous determination of theophylline (THP), guaifenesin (GUI) and guaiacol (GUA, a guaifenesin impurity) by HPTLC on silica gel with ethyl acetate – hexane – methanol - ammonia 65:35:10:2. Detection and quantification by densitometry at 275 nm. The hRf values were 13, 35 and 80 for THP, GUI and GUA, respectively. The linearity range was 0.4–2 μg/band for both THP and GUI, and 0.4–1.2 μg/band for GUA. Validation of the proposed method according to ICH guidelines. Statistical comparison of the results with RP-HPLC showed no difference regarding accuracy and precision.
