Retention Indices As the Best Reproducible Chromatographic Parameters for the Characterization of Phenolic Compounds in Reversed-Phase High-Performance Liquid Chromatography

“…Thus, RIs can be successfully used as an additional chromatographic parameter in the analysis of phenolic compounds in complex naturally occurring materials [25][26][27].…”

The influence of medicine plant extracts on viability of yeast cells of Saccharomyces cerevisiae and Saccharomyces carlsbergensis under the action of ionizing radiation

“…Control of the quantity and quality of stress and antistress factors, selective enhancement or suppression of their action on microbial cells can be used to obtain positive effects in the systems of synthesis and destruction of substances, control of growth and physiological activity of microorganisms with simultaneous, conjugate flow of microbiological, chemical and photochemical processes; taking into account the possibility of pro-oxidant and antioxidant effects of the components of the nutrient medium on the cells of microorganisms. Substances with oxidant and pro-oxidant activities can be formed directly during the cultivation of microorganisms during chemical and photochemical processes, while some of them may exhibit both pro-oxidant and antioxidant properties; combating phenomena such as blooming of reservoirs, the effects of toxic substances of algae and plants during photosensitization on biota and humans; improvement of biological purification methods using IOP Publishing doi:10.1088/1755-1315/1061/1/012051 2 microorganisms, microalgae and plants; the use of biologically active substances [4][5][6][7][8] and additives based on microorganisms and plants for feed, veterinary, food and medical prophylactic purposes, for post-radiation therapy.…”

Abrasive Stripping Square‐Wave Voltammetry of Blackberry, Raspberry, Strawberry, Pomegranate, and Sweet and Blue Potatoes

“…It is found in numerous fruits and vegetables including strawberries, raspberries, pomegranates, and walnuts (Tomas‐Barberan and Clifford 2000). For quantitative determination of ellagic acid, the methods of high‐performance liquid chromatography (Amakura and others 2000; Kochetova and others 2007), spectroscopy (Chang and others 1996), and SWV (Cuartero and others 2011) were used. Flavonoids are electroactive and can be oxidized on a graphite electrode (Ignjatović and others 2002; de Lima and others 2007; Gutierrez and others 2010).…”
