Abstract:
The resistance mechanism of mandarin varieties towards Deuterophoma tracheiphila Petri, the causal agent of Mal-secco, (a citrus disease) has been investigated. From two mandarin varieties, Cleopatra and Avana, five flavones were isolated, identified and tested for their fungistatic activity. Four of the flavones were found potent, one of which 5, 4′-dihydroxy-6, 7, 8, 3′-tetramethoxy flavone, is a new compound, while a second, 5, 4′-dihydroxy 6, 7, 8-trimethoxy flavone, is reported for the first time to occur in citrus. © 1968.
