Abstract

The aim of the work is to determine the content of bioactive substances and elemental composition of St. John's wort herbs of different producers and reveal correlations between the contents of API and microelements.

Materials and Methods. The research used certified reference materials for organic substances produced by the company Fluka and for metal ions produced by O.V.Bogatsky Physicochemical Institute, and samples of herbs of St. John's wort of different producers.

Analytical equipment. Hewlett Packard 8452A spectrophotometer; Shimadzu LC-20 liquid chromatograph, equipped with UV detector and Phenomenex Luna C18 column; and Solaar S4 AA atomic absorption spectrophotometer (Thermo Electron Co., USA).

Statistical calculations were performed using the IBM SPSS-19 statistical software package.

Results and Discussion. The content of bioactive substances (hypericin, hyperoside, rutin, quercetin, and chlorogenic, neochlorogenic, rosemary and caffeic acids) and elemental composition have been investigated for samples of St. John's wort herb of four different producers. Significant variation in the content of organic compounds is registered. For example, the content of hypericin, one of the main active pharmaceutical ingredients of St. John's wort, varies 2-5 times. Statistically significant positive or negative correlations were found between the contents of certain elements (K, Mg, Fe, Mn, and Cd) and the content of organic substances (rutin, hyperoside, hypericin and hydroxycinnamic acids).

Conclusions. The content of biologically active substances, namely hypericin, rutin, hyperoside and studied hydroxycinnamic acids, varies considerably depending on the origin and elemental composition of St. John's wort herb samples.
