摘要：

Two novel anthocyanins have been isolated from the stem of Allium victorialis. By means of chemical degradation and spectroscopy, especially homo- and hetero-nuclear two-dimensional NMR techniques, the structures were determined to be cyanidin 3-O-(3 '', 6 ''-O-dimalonyl-beta-glucopyranoside) (76.6%) and cyanidin 3-O-(3 '',O-malonyl-beta-glucopyranoside) (13.8%). This is the first report of acylation of the 3-position in the sugar moiety of any anthocyanin. The stability of malonyl substitution in the 3 ''-position on glucose is higher than the corresponding 6 ''-malonylation.
