The plants of Boraginaceae and Polygonaceae family is the source of biologically active substances

Abstract

The objects of researching are herb and roots of Borago officinalis L. and Echium vulgare L of Boraginaceae family and Polygonum alpinum All. herb of Polygonaceae family. The method of columnar chromatography for separation of substances was fulfilled on various sorbents. The identification of released compounds was being carried out on the physical and chemical properties base of primary substances, the products of their transmutation, ultraviolet, infra-red of spectroscopy, Rf value on the chromatograms in various systems of solvents. There were marked nearly 29 substances among the plants under study. The flavonoids are presented in all studying objects. Borago officinalis herb and Echium vulgare herb and its roots are more rich with coumarins. Together with the substances of flavonoid and coumarin nature getting from the herb of the studying plants there were marked and identified the derivatives of cinnamic acid.
