Determination of carboxylic acid salts in pharmaceuticals by high-performance liquid chromatography after pre-column fluorogenic labelling

Autor: D. Bonazzi, Rita Gatti, E. Bousquet, Vanni Cavrini

Publikováno v: Biomedical Chromatography. 10:19-24

2-Bromoacetyl-6-methoxynaphthalene (Br-AMN) was used as a fluorogenic labelling reagent for high-performance liquid chromatographic (HPLC) analyses of pyroglutamic acid, 4-hydroxybutyric acid and thioctic acid in pharmaceutical formulations. The reac

Analysis of pharmaceutical creams: a useful approach based on solid-phase extraction (SPE) and UV spectrophotometry

Autor: Vanni Cavrini, D. Bonazzi, Vincenza Andrisano, Rita Gatti

Publikováno v: Journal of Pharmaceutical and Biomedical Analysis. 13:1321-1329

Solid-phase extraction (SPE) using C-18, diol and ion-exchange sorbents followed by UV spectrophotometric (conventional and derivative mode) assay was applied to the analysis of basic, acidic and neutral drugs commercially available in creams. A repr

HPLC determination of 18 β-glycyrrhetinic and glycyrrhizinic acids in toothpastes after solid phase extraction

Autor: Vanni Cavrini, Vincenza Andrisano, D. Bonazzi

Publikováno v: Chromatographia. 35:167-172

HPLC methods suitable for the selective and sensitive determination of 18 β-Glycyrrhetinic acid (GT) and Glycyrrhizinic acid (GZ) in toothpastes have been developed. The methods involve a preliminary quantitative solid phase extraction (C-18 sorbent

Analysis of flucytosine dosage forms by derivative UV spectroscopy and liquid chromatography

Autor: Vanni Cavrini, D. Bonazzi, Anna Maria Di Pietra

Publikováno v: Journal of Pharmaceutical and Biomedical Analysis. 9:401-407

A simple second-order derivative spectrophotometric method was developed for the selective determination of flucytosine (an antimycotic drug) in the presence of 5-fluorouracil (a cytotoxic agent), its synthetic precursor and degradation product. Trac
