Two new kaempferol glycosides (1 and 2) were isolated from the blue flowers of Nigella damascena cv ‘Ms Jekyll Blue’ along with a known anthocyanin (3). The structures of 1 and 2 were elucidated by application of chemical and spectroscopic methods. Compound (3) was a rarely observed anthocyanin in plants.
