Abstract

During a re-investigation of phenolic compounds from the dried crude drug material of St. John’s wort (Hypericum perforatum L.) 22 phenolic compounds were detected by HPLC; 14 of them were quantified using the same system. Twelve phenolic compounds were isolated from the plant material and their structures identified mainly by spectroscopic methods, among them quercetin-3-O-(2″-O-acetyl)-β-D-galactoside as a new natural product. Cryptochlorogenic acid, protocatechuic acid, 3-O-[Z]-p-coumaroylquinic acid, isoorientin, cyanidin-3-O-α-L-rhamnoside, and astilbin were obtained for the first time from this source; the earlier suspected neochlorogenic acid, 3-O-[E]-p-coumaroylquinic acid, mangiferin, miquelianin and guaijaverin were confirmed.
