[Lignins of Rhodiola rosea and Serratula coronata: peculiarities of chemical structure and antioxidant properties].

Data on comparative investigations of chemical structure of lignins from medical grassy plants Rhodiola rosea and Serratula coronata lignins were obtained. The NMR and ESR spectroscopy, and functional and element analysis were used. The high antioxidant activity of lignins was shown. Experimental evidence of anti-aging activity of Rhodiola rosea lignin on model objects Drosophila melanogaster were presented.
