High-Performance Thin-Layer Chromatography Densitometric Determination of β-Sitosterol in Phyllanthus Species

Quantitative determination of phyllanthin and hypophyllanthin in Phyllanthus species by high-performance thin layer chromatography.

A simple, precise and rapid high-performance thin-layer chromatographic method has been developed for the estimation of phyllanthin (1) and hypophyllanthin (2), the important lignans of Phyllanthus species, especially Phyllanthus amarus. Separation of 1 and 2 was carried out on silica gel 60 F254 layers eluted with hexane:acetone:ethyl acetate (74:12:8), and the analytes were visualised through...

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 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.

Simultaneous thin-layer chromatography-densitometric analysis of sibutramine and citalopram.

Due the presence of sibutramine and citalopram in a number of drugs, neurotransmitter reuptake inhibitors. Sibutramine reduces the reuptake of serotonin, norepinephrine, and dopamine; citalopram is an antidepressant drug of the selective serotonin reuptake inhibitor. The thin-layer chromatography-densitometric behavior of some centrally acting serotonin reuptake inhibitors has been studied. The...
