Antioxidant activities and α-Glucosidase Inhibition Effects of Chicories Grown in Hydroponics Added with Cr 3+ or Selenium

ABSTRACT - This study was carried out to investigate the effect on the growth and antioxidant activities ofCichorium intybus L.(CLE), Cichorium intybus L. var. folisum ‘treviso’ (CLET), Cichorium intybus L. var. folisum‘rosaitaliana’ (CLER) in hydroponics added with Cr 3+ or Selenium (Se) for 4 weeks. Total polyphenol, total flavonoidscontents and FRAP values of three species of chicory were grown hydroponically with Cr 3+ or Se were increased.These extracts were also showed stronger DPPH and ABTS scavenging activity than chicory extracts. In particular,chicories added with Cr 3+ had higher antioxidant activities than chicories added with Se. CLER and CLE extractsadded with Cr 3+ were also showed α -glucosidase inhibition activities. These results indicate that chicories were culti-vated in culture fluid added with Cr 3+ or Se could be used as high functional vegetables. Key words : chicory, Cr 3+ , Selenium, antioxidant activity, α-glucosidase inhibition 환경오염으로 인해 자연으로부터 얻는 식품의 오염이 증가하고, 농업 생산성을 높이기 위해 사용되는 각종 농약의 남용으로 인해 식품의 안전성에서 많은 문제가 대두되고 있다
