In garden forms of Antirrhinum majus yellow flowers contain the aurone glucoside aureusin (XXI, R = glucose), luteolin and apigenin gly-... 

Aurones. Besides aureusidin (XXI, R == H), isolated from Antirrhinum majus, and leptosidin (XXIV), isolated from Coreopsis and Leptosyne... 

Aurones are found in a number of flowers of some Scrophulariaceae (e.g., snapdragon [Antirrhinum majus]) and Compositae (e.g.. Coreopsis, Cosmos, and Dahlia). The yellow snapdragon flower is probably one of the best sources of aurones in the vacuoles of the epidermal cells of the flowers. In some other plant species, however, aurones are also found in the bark, wood, leaves, seedlings, and nectar. In 2001, the occurrence of aurone (4 -chloroaurone) in marine organisms has been reported [187]. However, its stmcture was revised to 3-(4 -chloroisocoumarin) later [188].
