  1. In vitro and in vivo evaluation of the antioxidant and prooxidant activity of phenolic compounds obtained from grape (Vitis vinifera) pomace.

    Molecules 19(12):21154 (2014) PMID 25521116

    The antioxidant and/or prooxidant ability of extracts obtained from wine waste were analyzed using in vitro and in vivo assays. Cyclic voltammetry was used as the in vitro assay to determine the antioxidant and/or prooxidant properties and, the in vivo effect on mycelial growth of the fungus Bot...

  2. Characterization of extracts from winery by-products with antifungal activity againstBotrytis cinerea

    Industrial Crops and Products 43:360 (2013)

    Highlights ► Phenolic compound of grape pomace from a mixture of Chilean varieties were analyzed. ► Hexane phase of the extracts presented lowest diversity of phenolic compounds. ► Hexane or chloroform fractions showed antifungal activity against Botrytis cinerea. ► A new use...
  3. Farnesol induces apoptosis-like phenotype in the phytopathogenic fungus Botrytis cinerea.

    Mycologia 105(1):28 (2013) PMID 22962358

    This study demonstrates that the isoprenoid farnesol produces a toxic effect on the phytopathogenic fungus Botrytis cinerea in solid and liquid media. In solid media farnesol retarded 72 h the beginning of mycelial growth. Also, it was demonstrated that the toxic effect is due to farnesol trigge...
  4. Antifungal activity of resveratrol against Botrytis cinerea is improved using 2-furyl derivatives.

    PLoS ONE 6(10):e25421 (2011) PMID 22022392 PMCID PMC3191159

    The antifungal effect of three furyl compounds closely related to resveratrol, (E)-3,4,5-trimethoxy-β-(2-furyl)-styrene (1), (E)-4-methoxy-β-(2-furyl)-styrene (2) and (E)-3,5-dimethoxy-β-(2-furyl)-styrene (3) against Botrytis cinerea was analyzed. The inhibitory effect, at 100 µg ml(-1) of compo...
  5. In vitro antifungal activity of the diterpenoid 7 alpha-hydroxy-8(17)-labden-15-oic acid and its derivatives against Botrytis cinerea.

    Molecules 14(6):1966 (2009) PMID 19512998

    We investigated the inhibitory effect of the natural diterpenoids, 7alpha-hydroxy-8(17)-labden-15-oic acid (salvic acid, 1), 7alpha-acetanoyloxy-8(17)-labden-15-oic acid (acetylsalvic acid, 2) and the hemisynthetic diterpenoids 7alpha-acyloxy-8(17)-labden-15-oic acids derivatives, 7alpha-propano...

  6. Botrytis cinerea isolates collected from grapes present different requirements for conidia germination.

    Mycologia 101(3):287 (2009) PMID 19537202

    Botrytis cinerea presents high variability in several biological traits, which can be explained by the high degree of genotypic diversity among isolates. Because this genetic variability might be related to phenotypic differences the requirements for conidia germination of three natural isolates...
  7. In vitro sensitivity of Botrytis cinerea to anthraquinone and anthrahydroquinone derivatives.

    Journal of Agricultural and Food Chemistry 53(26):10080 (2005) PMID 16366698

    The effect on mycelial growth of the fungus Botrytis cinerea of a set of structurally related tricyclic hydroquinones [9,10-dihydroxy-4,4-dimethyl-2,3,5,8-tetrahydroantracen-1(4H)-one and 9,10-dihydroxy-4,4-dimethyl-5,8-dihydroanthracen-1(4H)-one derivatives] and tricyclic quinones [4,4-dimethyl...
  8. Differences in the initial events of infection of Botrytis cinerea strains isolated from tomato and grape.

    Mycologia 97(2):485 (2005) PMID 16396356

    Various stages of the infection process among B. cinerea strains isolated from tomatoes or grapes, belonging to different genetic groups, were compared. It was found that strains of B. cinerea isolated from either grapes or tomatoes showed differences in adhesion patterns and in the percentage o...
  9. Characterization of the antifungal activity on Botrytis cinerea of the natural diterpenoids kaurenoic acid and 3beta-hydroxy-kaurenoic acid.

    Journal of Agricultural and Food Chemistry 52(10):2821 (2004) PMID 15137820

    The antifungal activity on Botrytis cinerea of the diterpenoids 3beta-hydroxy-kaurenoic acid and kaurenoic acid, obtained from the resinous exudates of Pseudognaphalium vira vira, was determined. 3beta-Hydroxy-kaurenoic acid reduced the mycelial growth of B. cinerea in solid and liquid media. Ad...
  10. Regulatory aspects of endoglucanase production by the brown-rot fungusGloeophyllum trabeum

    Experimental Mycology 16(4):253 (1992)

    Regulation of endoglucanase formation by the brown-rot fungus Gloeophyllum trabeum was investigated. This fungus produced endoglucanases in the presence of monosaccharides such as glucose or mannose as the sole carbon source, but the expression of these enzymes was four to five times ...
