Those structures and previously isolated pure compounds have been tested in their antibacterial activity on phytopathogenic bacteria. Ketone 2 and the flavonoid hesperetine 10 showed antibacterial activity on Erwinia carotovora subsp. carotovora, while the flavonoid 3-O-methylgalangine 4 showed activity on Clavibacter michiganensis subsp. michiganensis %K Heliotropium sinuatum %K resinous exudate %K antibacterial activity %K Erwinia carotovora carotovora %K Clavibacter michiganensis michiganensis %U http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-97072004000100001
