Five anthocyanins, cyaniclin 3-O-(2-O-beta-xylopyranosyl-6-O-(Z)-p-coumatoyl)-beta-galactopyranoside (2), cyaniclin 3-O-(2-O-beta-xylopyranosyl-6-O-(E)-p-coumaroyl)-beta-galactopyronoside (3), cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-(E)-caffeoyl)-beta-galactopyranoside (4), cyanidin 3-O-(2-O-beta-xylopyranosyl-6-Oacetyl)- P-galactopyra nos ide (5), and cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-acetyl)-beta-glucopyranoside (6), together with the known cyaniclin 3-O-(2-O-beta-xylopyranosyl)-beta-galactopyranoside (1), were isolated from red flowers of Camellia cultivar 'Dalicha' (Camellia reticulata) by chromatography using open columns. Their structures were subsequently determined on the basis of spectroscopic analyses, i.e., (1)H NMR, (13)C NMR, HMQC, HMBC, HR ESI-MS and UV-vis.
