Abstract:
It was determined phenolic compounds of the herb of Veronica prostrata L., Veronica chamaedrys L., Veronica officinalis L. by the method of high performance liquid chromatography (HPLC). Established quality composition and quantity content of flavonoids, hydroxycinnamic acids, coumarins and hydrolysable tannins. In the herb of Veronica prostrata L. it was revealed 5 hydroxycinnamic acids, the most abundant was rosmarinic acids – 0,41%, 3 flavonoids, the highest content was for apigenin and its glycosides – 0,34%, coumarin – 0,07%, 7 hydrolysable tannins, the highest content related to catechin – 1,45%; Veronica chamaedrys L. – 5 hydroxycinnamic acids (rosmarinic acid 1,31%), 5 flavonoids (rutin 0,26%), 3 coumarins (umbelliferone 0,17%), 5 hydrolysable tannins (epicatechin 0,06% and ellagic acid 0,06%); Veronica officinalis L. – 5 hydroxycinnamic acids (rosmarinic acid 1,41%), 2 flavonoids (isoquercetin 0,28%), 2 coumarins (umbelliferone 0,03%), 7 hydrolysable tannins (epigallocatechin 0,44%).
