CHARACTERIZATION OF POLYPHENOL PROFILE OF EXTRACTS OBTAINED FROM GRAPE POMACE AND SYNERGISTIC EFFECT OF THESE EXTRACTS AND FUNGICIDES AGAINST Botrytis Cinerea

ABSTRACT Botrytis cinerea is a phytopathogenic fungus that infects the aerial parts of approximately 250 plant species. Control of this fungus is based on synthetic fungicide application. However, it has been reported the detection of isolates of B. cinerea resistant to all fungicides. Due to the em...

Control of this fungus is based on synthetic fungicide application. However, it has been reported the detection of isolates of B. cinerea resistant to all fungicides.

In this work, extracts obtained from grape pomace of Syrah, Cinsault, or Cabernet Sauvignon varieties were analyzed. The phenolic composition in the fractions was different. Quercetin and kaempferol were observed in all fractions, in exception of Cinsault/chloroform fraction. Interestingly, gallic acid was found only in Cinsault extracts. The flavan-3-ols catechin and (-)-epicatechin are only found in Cinsault/ethyl acetate fraction.
