Triacylated cyanidin 3-(3X-glucosylsambubioside)-5-glucosides from the flowers of Malcolmia maritima

Three acylated cyanidin 3-(3X-glucosylsambubioside)-5-glucosides and one non-acylated cyanidin 3-(3X-glucosylsambubioside)-5-glucoside were isolated from the purple-violet or violet flowers and purple stems of Malcolmia maritima (L.) R. Br (the Cruciferae), and their structures were determined by chemical and spectroscopic methods.
