MENDOZA, LEONORA; MODAK, BRENDA; TORRES, RENE  and  COTORAS, MILENA. IN VITRO SENSITIVITY OF BOTRYTIS CINÉREA TO RESINOUS EXUDATES OF HELIOTROPIUM FILIFOLIUMAND GERANYL DERIVATIVES COMPOUNDS. J. Chil. Chem. Soc. [online]. 2008, vol.53, n.1, pp.1436-1438. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072008000100024.

The activity of the extract ofHeliotropium filifolium, of the natural compounds obtained from its resinous exudates, filifolinol and fihfohnyl senecionate, and of the synthetic derivative of filifolinol, filifolinoic acid, on the mycehal growth of the phytopathogenic fungus Botrytis cinérea was analyzed in liquid and solid media. The extract of H'. filifolium, filifolinol, and filifolinoic acid reduced mycehal growth of this fungus. The effect of these compounds was dose-dependant. The compound fihfohnyl senecionate was inactive in all the tested conditions. The extract of H'. filifolium and filifolinol retarded the germination of conidia of the fungus

Keywords : Botrytis cinérea; Heliotropium filifolium; geranyl derivatives; antifungal activity.
