High-Performance Thin-Layer Chromatography Fingerprinting of Ethnopharmacological Important Seeds of Wrightia tinctoria

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...

Qualitative Metabolism Assessment Using High Performance Thin Layer Chromatography

Quantitative Determination of L-DOPA in Seeds of Mucuna Pruriens Germplasm by High Performance Thin Layer Chromatography

Mucuna pruriens Linn. is an important medicinal plant used for treatment of Parkinson's disease and many others in ancient Indian medical system. L-DOPA extracted from seeds of Mucuna is a constituent of more than 200 indigenous drug formulations and is more effective as drug than the synthetic counterpart. A densitometric high performance thin-layer chromatographic (HPTLC) method was developed...

a high-performance thin-layer chromatography method for quantitative determination of quercetin in herbal products

A preparative high performance liquid chromatography method for separation of lecithin: comparison to thin-layer chromatography.

We have developed a high performance liquid chromatography (HPLC) method to separate lecithin from other phospholipid classes and to obtain lecithin from biologic materials. The separation was performed on a preparative 10-micron Spherisorb column with an optimized solvent system consisting of the following components: acetonitrile, isopropanol, methanol, water, and trifluoroacetic acid. The ad...
