| Abstract:
The content and chemical composition of polyphenolic acids in dry leaves of male and female forms of nettle (Urtica dioica L.) were investigated at different vegetative seasons. In both forms the concentration of polyphenolic acids increased up to the stage of full blooming and than decreased. The male form was characterized by a distinctly higher content of these compounds, especially m-hydroxybenzoic, p-hydroxybenzoic and elagic acids. The female form was characterized by a higher concentration of elagic acid, particularly in the fraction obtained after acid hydrolysis. | |
