Abstract
A thorough investigation of phenolic constituents of commercial dry extract of Hedera helix L. (Araliaceae) was carried out. Rutin (1), kaempferol 3-O-rutinoside (2), quercetin 3-O-glucoside (isoquercitrin, 5), and kaempferol 3-O-glucoside (astragalin, 12), quercetin (10), kaempferol (11), chlorogenic acid (3), neochlorogenic acid (4), 4,5- (6) and 3,5-O-dicaffeoyl-quinic (7) acids as well as rosmarinic (13), caffeic (8), and protocatechuic (9) acids were isolated and identified by spectroscopic methods. Compounds 4, 6, 7, 12, and 13 are reported for the first time for H. helix. Six main phenolics (1 -3, 6, 7, 9) were quantified by means of HPLC and capillary electrophoresis (CE).
