High performance thin layer chromatography analysis of seed extracts of Tudri Surkh (Cheiranthus cheiri)

Determination of polyphenolics in extracts of Potentilla species by high-performance thin-layer chromatography photodensitometry method.

INTRODUCTION Separation of polyphenolics in different plant materials using high-performance thin-layer chromatography (HPTLC) represents an effective method for their detection and quantification. OBJECTIVE To develop a simple, specific, precise, sensitive and accurate method for the simultaneous quantification of tiliroside (TRS), methyl brevifolincarboxylate (MBR) and ellagic acid (EA) in ...

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...

Thin Layer Chromatography and High Pressure Liquid Chromatography Profiling of Plant Extracts of Viola Odorata Linn

Medicinal plant contains matter that can be used for therapeutic reason or which are precursors for the production of useful drugs. Very few and periodic works are there in the literature regarding the phytochemistry and TLC of Viola odorata L. TLC profiling of plant extract gives an idea about the presence of various phytochemicals. Different Rf (Retention factor) value of various phytochemica...

Qualitative Metabolism Assessment Using High Performance Thin Layer Chromatography

Application of High Performance Thin Layer Chromatography for Qualitative Analysis of Isoflavones in Medicinal Plants

The retention behavior of commonly occurring compounds with estrogenic activity: daidzein, formononetin, genistein, prunetin, biochanin A and coumestrol on silica and silica modified with cyjanopropyl, aminopropyl, diol and octadecyl groups was investigated. Mixtures of methanol or acetonitrile with water and eluents such as chloroform, heptane and toluene with more polar modifiers: ethyl aceta...
