Abstract:
Novel flavonoids were formed in young leaves of apple (Malus$\times$domestica) after treatment with the dioxygenase inhibitor prohexadione-Ca, which is known to reduce the incidence and severity of fire blight caused by Erwinia amylovora and other plant diseases. The compounds were isolated and identified as luteoliflavan, luteoliflavan 5-glucoside, eriodictyol 7-glucoside and 6$''$-O-trans-p-coumaroyleriodictyol 3$\prime$-glucoside. These flavonoids represent a novel biosynthetic pathway in app...     »
