Regularities of Anthocyanins Retention in RP HPLC for 'Water–Acetonitrile–Phosphoric Acid' Mobile Phases
Autor: V. I. Deineka, L. A. Deineka, I. I. Saenko
Publikováno v: Journal of Analytical Methods in Chemistry, Vol 2015 (2015)
The influence of exchange of HCOOH (System 2) by phosphoric acid (System 1) for acidification of the “acetonitrile–water” mobile phases for reversed-phase HPLC of anthocyanins was investigated in the framework of relative retention analysis. Th

Hydrophilic interaction chromatography as an alternative to reversed-phase HPLC in determining anthocyanins and betacyanins
Autor: Victor I. Deineka, I. I. Saenko, L. A. Deineka, I. P. Blinova
Publikováno v: Journal of Analytical Chemistry. 71:297-301
We selected the conditions of hydrophilic interaction chromatography for separating anthocyanins and betacyanins using a diol stationary phase and mobile phases of acetonitrile–0.5 vol % phosphoric acid–water. Regularities of the separation of be

A float mechanism of retention in reversed-phase chromatography
Autor: L. A. Deineka, I. I. Saenko, Victor I. Deineka, A. N. Chulkov
Publikováno v: Russian Journal of Physical Chemistry A. 89:1300-1304
A float mechanism of retention in reversed-phase HPLC is proposed as an alternative to the known mechanisms of the distribution and hydrophobic expulsion of sorbate to the surface of a sorbent. Experimental data that the sorption of a flavylium struc

Specific features of the determination of betacyanins by reversed-phase high-performance liquid chromatography
Autor: L. A. Deineka, I. I. Saenko, Victor I. Deineka
Publikováno v: Journal of Analytical Chemistry. 70:892-896
The stability and behavior of beet betacyanins in reversed-phase HPLC and in solid-phase purification on Diapak C18 concentrating cartridges have been studied. It has been demonstrated that, in acidic mobile phases and solutions with pH < 4.0, the de

Regularities in adsorption of anthocyans by natural clays
Autor: A. N. Chulkov, I. I. Saenko, Victor I. Deineka, L. A. Deineka
Publikováno v: Russian Journal of Applied Chemistry. 82:794-800
Regularities of adsorption by clay of some commercial sorts of anthocyans extracted from plant materials are investigated. The interrelation between sorption ability and structure of sorbates is revealed. Introduction of organic solvent is shown prov
