IMPACT OF EXTRACTION PROCEDURE ON CHEMICAL PROFILE AND ANTIOXIDANT EFFECT OF VERONICA OFFICINALIS EXTRACT

Veronica officinalis is plant species used in traditional medicine worldwide, but its effects have not been investigated so far. Consequently, the aim of this research was to identify dominant compound in V. officinalis extracts and to determine the effect of ultrasound and extraction temperature on the content of that compound and total phenolic content. Moreover we investigated the correlation between the concentration of dominant compound and antiradical activity of tested extracts. The main compound in extracts was acteoside. Higher amount of total phenolics and acteoside were obtained using ultrasound-assisted extraction technique and higher temperatures. DPPH assay, which is used for measuring antiradical potential, showed that concentration of acteoside, as well as concentration of polyphenolic compounds, is directly correlated with antioxidative potentiality tested extracts
