Flow Injection Analysis Coupled with Carbon Electrodes as the Tool for Analysis of Naphthoquinones with Respect to Their Content and Functions in Biological Samples
MetadataShow full item record
Naphthoquinones are one of the groups of secondary metabolites widespread in nature, where they mostly appear as chromatic pigments. They embody broad-range of biological actions from phytotoxic to fungicidal. An anticancer effect of naphthoquinones stimulates an interest in determination and characterization of single derivatives of 1,2- and 1,4-quinones in biological samples. The main aim of this work was to suggest a technique suitable to determine lawsone, juglone and/or plumbagin in biological samples and to study of their influence on BY-2 tobacco cells.
KeywordsNaphthoquinones, Plumbagin, Lawsone, Juglone, BY-2 tobacco cells (Nicotiana tabaccum), Persian walnut (Juglans regia), Sensors, Flow analysis, Differential pulse voltammetry, Electrochemical detection, Carbon electrodes.
