A new simple High Performance Thin Layer Chromatographic (HPTLC) method for determination of Ethinylestradiol (EE) and Norgestimate (NGM) in combined tablet dosage form has been developed and validated. The mobile phase selected was Benzene: Ethyl acetate: Triethylamine (7: 2: 1 v/v/v) with UV detection at 280 nm. The retention factors for EE and NGM were found to be 0.62 ± 0.102 and 0.82 ± 0.123. The method was validated with respect to linearity, accuracy, precision and robustness. Results found to be linear in the concentration range of 200-1000 ng/band for EE and 1000-5000 ng/band for NGM. The method has been successfully applied for the analysis of drugs in pharmaceutical formulation. The % assay (Mean ± S.D.) was found to be 99.4 % ± 0.157 for EE and 99.8 % ± 0.14 for NGM.
