Effect of the method of harvesting on the yield and the content of phenolic compounds in artichoke (Cynara scolymus L.) herb

ANDRZEJ SAƁATA, HALINA BUCZKOWSKA

Abstract

The yield of an artichoke herb depended on number of harvests undertaken. Definitely higher yield of an air-dried herb was obtained from twofold (0.74 kg/m2) and threefold (0.65 kg/m2) harvest in comparison to single one (0.46 kg/m2). The content of polyphenolic acids in herb obtained from threefold harvest (in 1st decade of August, September and October) and from the twofold harvest (in 1st decade of September and October) was over 50% higher than that from the single harvest (1st decade of October). Content of flavonoids, depending on number of harvest, varied from 0.23% to 0.36% in the artichoke herb.
