Publikováno v: Journal of Pharmaceutical and Biomedical Analysis. 83:19-27

An HPLC method for determination of related substances in temozolomide drug substance was developed. Particular attention was paid to the stability studies due to the fact that temozolomide is unstable in a solution and quickly decomposes to its main

Development and validation of high performance liquid chromatography with a spectrophotometric detection method for the chemical purity and assay of nepafenac

Autor: Łukasz Jedynak, Maria Puchalska, Elżbieta Lipiec-Abramska, Joanna Zagrodzka, Jacek Roszczynski, Adam Formela, Marcin Cybulski

Publikováno v: Journal of pharmaceutical and biomedical analysis. 91

The study is a proposition of the application of high performance liquid chromatography (HPLC) with a spectrophotometric UV range detector to analyze the chemical purity and assay of nepafenac, an active pharmaceutical ingredient (API). During litera

Blue natural organic dyestuffs--from textile dyeing to mural painting. Separation and characterization of coloring matters present in elderberry, logwood and indigo

Autor: Agata Miszczak, Maria Puchalska, Katarzyna Pawlak, Maciej Jarosz, Elżbieta Rosłoniec

Publikováno v: Journal of mass spectrometry : JMS. 41(5)

Natural dyestuffs used for painting or dyeing of textiles are complex mixtures of compounds of various chemical properties. Proper identification of the dye used by a painter and, even better, its origin is possible only when its compositional ‘fin

Identification of indigoid dyes in natural organic pigments used in historical art objects by high-performance liquid chromatography coupled to electrospray ionization mass spectrometry

Autor: Helena Hryszko, Irmina Zadrozna, Maria Puchalska, Maciej Jarosz, Kasia Połeć-Pawlak

Publikováno v: Journal of mass spectrometry : JMS. 39(12)

Pigments are among the most important components of historical paintings and textiles and their nature provides the unique character of color. They can be divided into two main groups: inorganic and organic, extracted from plants or animals. Their id

Publikováno v: Journal of mass spectrometry : JMS. 38(12)

Capillary electrophoresis with UV/visible diode-array detection (DAD) and electrospray mass spectrometric (ESI-MS) detection were used for the identification of anthraquinone color components of cochineal, lac-dye and madder, natural red dyestuffs of
