The flavonoids (rutin, quercetin, and isoquercetin) and hypericin are the main active substances of St. John's wort (Hypericum perforatum). They support regeneration of human body cells, provide disinfection, and act as antidepressant, antiviral, and anti-inflammation tools. Such large spectrum of the applicable functions depends on the quantity of each substance. The objective of this paper is to determine the regularities of the quantitative variation of rutin, quercetin, isoquercetin and… CONTINUE READING
