| Abstract: | Two high-molecular water-soluble preparations with high anticomplement and antioxidant activity were isolated from the roots of Symphytum asperum and S. caucasicum. Their main chemical constituent was found to be poly[oxy-1-carboxy-2-(3,4-dihydroxyphenyl)ethylene] according to IR and NMR spectroscopy.
