Abstract :

Recently high-molecular fractions were isolated from species of Boraginaceae family Symphytum asperum and S. caucasicum. Based on the IR and NMR spectroscopy data, poly[3-(3,4 dihydroxyphenyl)glyceric acid] (PDPGA) was confirmed to be the major component of these fractions. This compound represents a new class of natural polyethers with a residue of 3-(3,4 dihydroxyphenyl)glyceric acid as the repeating unit. Polymer possesses immunomodulatory (anti-complementary), antioxidant, anti-inflammatory and wound-healing properties. Phytochemical investigation of roots and stems of Symphytum asperum L. was carried out in order to define starting substances for biosynthesis of PDPGA. The solid-liquid extraction technique was chosen as the first step for isolation the compounds probably containing the fragments of PDPGA, followed by the investigation using UHPLC-Q-TOF/MS technique. The UHPLC-Q- TOF/MS analysis of extracts of S. asperum roots/ stems revealed the presence of low molecular weight compounds such as caffeic, rosmarinic, chlorogenic and salvianolic acids as well several oligomers. The obtained results show that the comfrey roots/stems can be used as a source for the isolation of low molecular weight biologically active compounds.
