Ellagic acid content in fruits of selected strawberry cultivars.

摘要

Ellagic acid is a biologically active compound, regarded as preventive against various diseases and demonstrates anticarcinogenic and antioxidant effects. In Poland, one of the five largest strawberry producers, the supply of these fruits is significant; therefore exploration of this subject and dissemination of the knowledge concerning their nutritional values and health-related properties is important. The aim of the study was to determine the content of ellagic acid in the most popular, selected strawberry cultivars in Poland. Fruits of the strawberry cultivars under examination differed significantly in ellagic acid content. The content of the analysed component ranged from 452.5 mg kg-1 fresh weight (4,575.6 mg kg-1 dry matter) in fruits of the 'Heros' cultivar to 1,193.8 mg kg-1 fresh weight (14,215.0 mg kg-1 d.m.) in fruits of the 'Camarosa' cultivar. The highly diversified content of ellagic acid in fruits of individual cultivars, grown in similar soil and weather conditions and subjected to the same agricultural treatments, indicates that the content of the analysed phenolic acid depends not only on the fruit species, but also on the cultivar.
