A new acylated anthocyanin was isolated from the blue flowers of Evolv
ulus pilosus cv 'Blue Daze' as a major anthocyanin. The structure of t
his pigment was determined to be delphinidin -(6-O-(trans-3-O-(beta-D-
glucopyranosyl)-caffeyl)- noside)-5-O-((6-O-malonyl)-beta-D-glucopyran
oside) by chemical and spectral methods.
