โœฆ Synopsis


Addition of anthocyanins with nucleophilic agents normally occurs at the C-4 centre and the isolation of C-2 adducts between acetone and cyanidin-3-and delphinidin-3-rutinosides is the first definitive demonstration of the reactivity of this carbon site. These C-2 addition products were isolated as diastereoisomers and their chemical structures elucidated by 1D and 2D NMR spectroscopy.

A novel C-glycosylanthocyanin was isolated from the flowers of Tricyrtis formosana cultivar Fujimusume, and its structure was elucidated to be 8-C-b-D-glucopyranosylcyanidin 3-O-(6-O-malonyl)-b-D-glucopyranoside by chemical and spectroscopic methods.
