dcterms:description
Recent papers discuss relation of flavonoid compounds and tumour diseases. In addition it is impossible to say that effect of flavonoids is positive or negative without epidemiological studies. That is why it is necessary to suggest a simple, low cost and sensitive technique for determination of these compounds in biological material. The electrochemical techniques are very suitable for these purposes. Here we suggested the electrochemical technique for the determination of rutin, quercetin, quercitrin, chrysin and diosmin by square wave voltammetry using carbon paste electrode as a working electrode. The limits of detection of the studied flavonoids were about tens of nM, except diosmin (tens of microM). Recent papers discuss relation of flavonoid compounds and tumour diseases.
