Detection by spraying with 10 % H2SO4 in ethanol and heating at 105 ºC. Identification by comparison with the standard. Quantification by densitometry at 530 nm. Validation of the method by investigation of precision (RSD=2.2 % n=5 within plate and 3.0 % n=5 plate-to-plate), linearity range (0.45-2.28 µg/spot r=0.998), repeatability, reproducibility, and recovery (98.1 %, n=5, RSD=3.4 %).
IPC 56th 2004, Abstract No. GP-5. Simultaneous HPTLC determination of amlodipine and atenolol on silica gel with ethyl acetate - methanol - ammonia 60:40:3. Quantitative determination by scanning at 254 nm. The method was found linear in the range of 0.5 – 5.0 mg/mL amlodipine and 5.0 mg – 50 mg/mL atenolol. Recovery was 98.11 – 101.5 % for both of the compounds. The method was validated for accuracy, precision, linearity, specificity, LOD, and LOQ.
