Résumé :

BACKGROUND: Juglans nigra L. is a species of trees in the Juglandaceae family. This plant of the genus Juglans L. has not been sufficiently studied in comparison with other species, including Juglans regia L. It is a perspective medicinal plant raw material, its derivatives have an antimicrobial, general tonic effect. The known antimicrobial and general tonic activity of Juglans L preparations presented on the pharmaceutical market is probably due to substances of a flavonoid nature. These data indicate the relevance of studying the flavonoids of the Juglans nigra L. bark. AIM: The aim o

Résumé :

Abstract The amino acid analysis method using precolumn phenylisothiocyanate (PITC) derivatization and liquid chromatography was modified for accurate determination of methionine (as methionine sulfone), cysteine/cystine (as cysteic acid), and all other amino acids, except tryptophan, in hydrolyzed samples of foods and feces. A simple liquid chromatographic method (requiring no derivatization) for the determination of tryptophan in alkaline hydrolysates of foods and feces was also developed. Separation of all amino acids by liquid chromatography was completed in 12 min compared with 60-90 min

The aim of this study was the validation of methods of quantitative determination of nifedipine in tablets by liquid chromatography. The chromatographic analysis was performed on nifedipine liquid chromatograph Agilent 1290 Infinity II LC System. A validation of methods of quantitative determination of nifedipine by high performance liquid chromatography tablets was performed. It was established that the method proves the requirements of the State Pharmacopoeia of Ukraine for the main validation parameters: specificity, accuracy, linearity, robasnist.

Résumé :

In previous days, Column chromatography was used for qualitative as well as quantitative analysis but Column chromatography is an extremely time consuming process. This leads to the development of novel preparative liquid chromatography in which mobile phase flows down by positive air pressure called as Flash chromatography. Flash Chromatography is a rapid form of preparative column chromatography. Flash chromatography, also known as medium pressure chromatography, was popularized several years ago by Clark Still of Columbia University, as an alternative to slow and often inefficient gravity-f
