HPTLC–densitometric and HPTLC–MS methods for analysis of flavonoids

Journal of Liquid Chromatography and Related Technologies, 2018
ABSTRACTHPTLC silica gel plates without and with fluorescence indicator F254 in combination with n-hexane–ethyl acetate–formic acid (20:19:1, v/v/v) as a developing solvent were explored for the HP...

Determination of isopropylthioxanthone (ITX) in milk, yoghurt and fat by HPTLC-FLD, HPTLC-ESI/MS and HPTLC-DART/MS

Analytical and Bioanalytical Chemistry, 2006
Two new HPTLC methods for quantification of isopropyl-9H-thioxanthen-9-one (ITX) in milk, yoghurt and fat samples have been developed. Extraction of ITX from milk and yoghurt was performed with a mixture of cyclohexane and ethyl acetate by employment of accelerated solvent extraction (ASE).

HPTLC determination of ketorolac tromethamine

Journal of Pharmaceutical and Biomedical Analysis, 2000
A High Performance Thin Layer Chromatography (HPTLC) method for quantification of ketorolac tromethamine, a non-narcotic and non-steroidal agent was developed. The mobile phase composition was chloroform-ethyl acetate-glacial acetic acid (3:8:0.1, v/v/v). Spectrodensitometric analysis of ketorolac tromethamine was carried out at 323 nm. The calibration

Determination of Citalopram in Tablets by HPLC, Densitometric HPTLC, and Videodensitometric HPTLC Methods

Journal of Liquid Chromatography & Related Technologies, 2005
Abstract Three simple, rapid, and accurate analytical methods for the determination of citalopram in tablets were developed. The high performance liquid chromatography method was carried out using Waters Nova‐Pak C18 column with a mobile phase composed of methanol–0.067 M phosphate buffer pH 2.00 (55:45, v/v), UV‐VIS detector at 239 nm, and moclobemide
