Abstract

Chicories produce a wide range of vegetables with important nutritional value. We determined the variation of sterol, total polyphenol, nitrate contents and antioxidant capacity (SC, TPC, NC, AC) in endive leaves and stem-chicory novel vegetables, cultivated in two Italian regions. Within a given area, the SC was similar in smooth- and curly leafed endives (106.3-176.0 mg/kg FW); sitosterol and stigmasterol were major fractions (45-56 versus 38-43%). The stem SC was independent of landrace (101.5-118.6 mg/kg FW); sitosterol prevailed on stigmasterol and fucosterol (73-76 versus 12-14% versus 8-9%); the latter reached 15.7 mg/kg FW, conferring value as potential antidiabetes food. The planting site affected the AC and TPC of endives (893.1-1571.4 ?mTE/100 g FW, 30.8-76.1 GAE100/g FW) and chicory stems (729.8-1152.5 ?mTE/100 g FW; 56.2-124.4 GAE100/g FW), while the NC was recurrently below dangerous thresholds. PCA showed that environment was the major cause of variation, though it modestly affected these parameters.
