[Novel biologically active polymer of 3-(3,4-dihydroxyphenyl)glyceric acid from two types of the comphrey Symphytum asperum and S. caucasicvum (Boraginoceae)].
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.
