Determination of dithiodiglycolic acid in cold wave lotions by high performance thin layer chromatography.

Determination of Ursolic Acid a Biomarker in Different Swertia Species through High Performance Thin Layer Chromatography

A simple highly precise method has been established for the determination of ursolic acid in three species of Swertia viz. S. angustifolia, S. paniculata, and S. alata. The assay combines identification and quantification of the analyte on silica gel 60GF254 HPTLC plates with visualization under UV light and scanning at 510 nm.

Determination of carotenes by thin-layer chromatography.

The carotenoids of yellow, red and tangerine tomato fruits were separated and identified by thin-layer chromatography (TLC). β-carotene is extracted with a mixture content hexan and acetone. The various systems of adsorbents and solvents for TLC of carote and tomato carotenes were examined, and it was revealed that the most suitable TLC system for separation and identification was silica gel pl...

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 ...

determination of gamma - aminobutyric acid by high-performance liquid chromatography

gamma-aminobutyric acid is the main inhibitory amino acid neurotransmitter in several areas of the brain. measurement of gamma-aminobutyric acid in the brain will help elucidate its metabolic rote and diagnostic value. the liquid chromatography (lc) system consisted of a delivery pump. male rats (150-250g) were used in this study. the brain was rapidly removed from decapitated animals. trie chr...
