Table 2: Results of methylation analysis and AGP determination of St. John’s Wort polysaccharides. Data indicate the respective molar composition [%], calculated from results of HPAEC-PAD and silylation analysis. AGP amounts were detected by the agar diffusion test according to van Holst and Clarke, 1985 [20].
