Abstract
  • The present work reports preliminary results of the biochemical characterization of part of Cynara germplasm collected and multiplied by CNR-IGV, Bari (Italy) during the first year of 'CYNARES' EU project. Seventeen artichoke cultivars, with different geographical origin and morphological traits, were characterized for their polyphenol and inulin content. Plants were field grown in Policoro, MT (Southern Italy) with usual cultural practices. Buds of all cultivars, with size typical for each cultivar at commercial stage of harvesting, were picked on the third week of April 2008 and analyzed for their polyphenol and inulin content. The content of chlorogenic acid, dicaffeoylquinic acids, apigenin glycoside and inulin was determined by HPLC on the edible portion of the buds (hearts). Chlorogenic acid content ranged from about 200 to 600 mg 100g-1 f.w., the sum of dicaffeoylquinic acids ranged from about 400 to 950 mg 100g-1 f.w, while the apigenin glycoside content was between 10 and 20 mg 100g-1 f.w. Regarding the inulin content, remarkable differences among the cultivars were found; it ranged from about 1000 to 4000 mg 100g-1 f.w. The results of this study provide preliminary information about the variability of the considered biochemical parameters. In particular, regarding polyphenol content, it was noticed a different relative distribution of the most representative compounds in the different cultivars. For this purpose, the same trials are in progress for the second year, to evaluate the reproducibility of results through the two years and possible correlations with molecular data that have been collected on the same cultivars.
