An unusual acylated malvidin 3-glucoside from flowers of Impatiens textori Miq. (Balsaminaceae).
Acylated malvidin 3-glucoside was isolated from the purple flowers of Impatiens textori Miq. as a major anthocyanin component along with malvidin 3-(6''-malonyl-glucoside). Its structure was elucidated to be malvidin 3-O-[6-O-(3-hydroxy-3-methylglutaryl)-beta-glucopyranoside] by chemical and spectroscopic methods.
