Development and Validation of High Performance Thin Layer

A simple, specific and precise high performance thin layer chromatographic method was developed and validated for estimation of Brimonidine tartrate as bulk drug and in ophthalmic solutions. The chromatographic development was carried out on precoated silica gel 60 F254 aluminium plates using mixture of Methanol: Ammonia (8:0.2 v/v) as mobile phase and densitometric evaluation of band was carri...

Quantitative Estimation of Efavirenz by High Performance Thin Layer Chromatography

A simple, accurate, and precise HPTLC method has been developed and validated for the estimation of efavirenz from bulk drug and capsule formulations. The separation was achieved on TLC plates using an appropriate solvent system. The spots so developed were densometrically scanned at 247 nm. The linearity of the method was found to be within the concentration range of 1-40 μg/ml. The validation...
