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