Thin-layer Chromatography of Lipids
There has been a tendency to discount thin-layer chromatography (TLC) in recent years because of the availability of high-performance liquid chromatography (HPLC) methods that appeared to offer greater versatility and ease of quantification, amongst other reasons. However, TLC has made a comeback, largely because of the high reproducibility and lower costs of commercial pre-coated plates. It is...
متن کاملAnalysis of brain lipids by high performance thin-layer chromatography and densitometry.
We have devised a high performance thin-layer chromatography (HPTLC) densitometry method to resolve the major lipid classes of brain tissue. We used DEAE-Sephadex column chromatography to separate the total lipid into neutral and acidic lipid fractions. The lipid fractions were then spotted on separate HPTLC plates and chromatographed in one dimension using two solvent systems. Quantitation was...
متن کاملQuantitative 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...
متن کاملSkin diseases associated with the depletion of stratum corneum lipids and stratum corneum lipid substitution therapy.
The skin is the largest organ of the body, whose main function is to protect the body against the loss of physiologically important components as well as harmful environmental insults. From the inside to the outside, the skin comprises three major structural layers: the hypodermis, the dermis and the epidermis. The epidermis contains four different sublayers, the stratum corneum (SC), stratum g...
