An acylated delphinidin glycoside in the blue flowers of Evolvulus pilosus
摘要:
A new acylated anthocyanin was isolated from the blue flowers of Evolvulus pilosus cv 'Blue Daze' as a major anthocyanin. The structure of this pigment was determined to be delphinidin 3-O-(6-O-(trans-4-O-(6-O-(trans-3-O-(beta-D-glucopyranosyl)-caffeyl)- beta-D-glucopyranosyl)-caffeyl)-beta-D-glucopyranoside)-5-O-((6-O-malonyl)-beta-D-glucopyranoside) by chemical and spectral methods.
