PINUS SYLVESTRIS L. PLANT POLYPHENOLS
Keywords:
polyphenols, system, ethyl acetate, chloroform, hexane, extraction, precipitation, qualitative reactionsAbstract
In this paper, promising methods for the extraction of polyphenols from the plant Pinus Sylvestris L., physicochemical methods of their identification are introduced, extracts are obtained from ordinary pine bark and cones, from which the sum of polyphenols is extracted and the bark and dome polyphenols were compared comparatively.
