Content of flavan-3-ol monomers and gallic acid in grape seeds by variety and year

Popis výsledku v původním jazyce

The content of flavan-3-ol monomers and gallic acid in grape seeds in the samples from the gene collection of Viticulture Research Station Karlštejn (Czech Republic) was investigated. The presence of catechin, epicatechin, epigallocatechin, epicatechin gallate and gallic acid was confirmed in these samples, other flavan-3-ol monomers like gallocatechin or epigallocatechin gallate were below the limit of detection. As major flavan-3-ol monomers, catechin and epicatechin with 85 percent were detected. The average content of catechin in grape seed was 4454 mcg g-1, 3085 mcg g-1 epicatechin, 600 mcg g-1 epigallocatechin, 457 mcg g-1 gallic acid, and 352 mcg g-1 epicatechin gallate. Variety had the main impact on phenolic content followed by vintage. The average sum of flavan-3-ol monomers in grape seeds in white varieties was 7601 mcg g-1 and 10869 mcg g-1 in red varieties, with 10050 mcg g-1 in 2012 and 7846 mcg g-1 in 2013 were found on average in all varieties, respectively. The highest phenolic conte
