Abstract

MODAK, BRENDA; TORRES, RENÉ; WILKENS, MARCELA  and  URZUA, ALEJANDRO. ANTIBACTERIAL ACTIVITY OF COMPOUNDS ISOLATED OF THE RESINOUS EXUDATE FROM HELIOTROPIUM SINUATUM ON PHYTOPATHOGENIC BACTERIA. J. Chil. Chem. Soc. [online]. 2004, vol.49, n.1, pp.1-3. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072004000100001.

From the resinous exudates of Heliotropium sinuatum have been isolated and characterized two compounds, pentaeicosanol 1 and 1-hydroxy-3-doeicosanone 2. 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

Keywords : Heliotropium sinuatum; resinous exudate; antibacterial activity; Erwinia carotovora carotovora; Clavibacter michiganensis michiganensis.
