Quantitative analysis of propranolol hydrochloride by high performance thin layer chromatography

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...

Quantitative Analysis of Valsartan and Hydrochlorothiazide in Tablets by High Performance Thin-layer Chromatography

A new, simple, accurate, and precise high-performance thin-layer chromatographic (HPTLC) method has been established for simultaneous analysis of valsartan and hydrochlorothiazide in tablet formulations. Standard and sample solutions of valsartan and hydrochlorothiazide were applied to precoated silica gel G 60 F254 HPTLC plates and the plates were developed with chloroform–ethyl acetate–acetic...

Simultaneous Estimation of Nebivolol Hydrochloride and S- Amlodipine Besylate by High Performance Thin Layer Chromatography

A simple, rapid, and reliable HPTLC method has been established for simultaneous determination of Nebivolol and S-Amlodipine in pharmaceutical dosage forms. Identification and quantification were performed on silica gel 60 F254 HPTLC plates, prewashed with methanol, with chloroform:toluene:methanol:glacialacetic acid, (5:2:3:0.1, v/v/v/v), as mobile phase. This system furnished compact bands fo...

Determination of oxycodone hydrochloride in oral solutions by high-performance thin-layer chromatography/densitometry.

A thin-layer chromatography/densitometry method was developed and validated for the determination of oxycodone hydrochloride in oral solutions by using silica gel plates. A horizontal technique was used for development of the plates. The optimum composition for the mobile phase, which provided a suitable Rf value of 0.6 for oxycodone, was propanol-acetic acid-water-25% ammonia-methanol (20 + 1 ...
