New phenolic compounds from Kokuto, non-centrifuged cane sugar

Five new phenolic compounds, 4-(beta-D-glucopyranosyloxy)-3,5-dimethoxyphenyl-propanone (8), 3-[5[(threo) 2,3-dihydro-2-(4-hydroxy-3-methoxyphenyl)-3hydroxymethyl-7-methoxybenzofuranyl]-propanoic acid (12), 2-[4-(3-hydroxy-1-propenyl)-2,6-dimethoxyphenoxyl-3-hydroxy-3-(4-hydroxy-3,5-dimethoxy- phenyl)propyl-beta-D-glucopyranoside (13), 4-[(erythro) 2,3-dihydro-3(hydroxymethyl)-5-(3-hydropropyl)-7-methoxy-2-benzofuranyl]-2,6-dimethoxyphenyl-beta-D-glucopyranoside (14), 9-O-D-xylopyranoside of icariol A(2) (15), and known phenolic compounds were isolated from Kokuto, non-centrifuged cane sugar (Saccharum officinarum L.). Their structures were determined by a spectral investigation.
