볶음 치커리의 생리활성

Abstract

This study was carried out to investigate physiological activities of chicory root (Cichorium intybus L. var. sativus). The anti-hepatotoxic activity of roasted chicory was studied using primary cultured rat hepatocytes where cytotoxicity was induced by galactosamine. The water extract of roasted chicory did not induced of cytotoxicity in primary cultured rat hepatocytes. Treatment with 5mM galactosamin for 5.0 hr showed maximum increase in activity of lactic dehydrogenase (LDH) released in the medium. The water extract of roasted chicory inhibited significantly and dose-dependently the release of LDH activity increased by galactosamine-induced cytotoxity. The antidiabetic activity of water extract of roasted chicory was examined in streptozotocin induced diabetic rats. The increased blood glucose level in the streptozotocin induced diabetic rats was significantly dereased by the administration of chicory extract (800㎎/㎏). Chicory water extract(800㎎/㎏) prevented weight losses in streptozotocin induced diabetic rats. The antimutagenic activities of chicory water extract were tested using Salmonella thyphimurium YG 1024 as tester strains and 2-aminofluorence as a potent carcinogen in the presence of S-9 mix. No mutagenic activities of the water extracts of roasted chicory were observed on all the tested strains at dose 10~5,000㎍ per plate. Water extract of roasted chicory did not inhibit the mutagencities of Salmonella thyphimurium YG 1024 induced by 2-aminofluorene.
