국내산 치커리의 생리적 기능성을 알아보기 위해 실험한 결과는 다음과 같다. 복음치커리의 물추출물은 간세포의 독성을 유발시키지 않았으며, 5 mM의 galactosamine을 5시간 배양하였을 때 LDH의 활성이 가장 높게 나타났다. 5 mM의 galactosamine으로 독성을 유발시킨 흰쥐의 간세포에 볶음치커리 물추출물을 투여한 결과 간세포로 부터 유리되는 LDH의 활성을 유의성 있게 감소시켜 간세포 보호 활성을 나타내었다. 볶음치커리 물추출물 800 mg을 당뇨 유발 흰쥐에 10일간 투여한 결과 혈당치는 297 mg/dl로 유의적으로 감소하는 경향을 나타냈었고, 체중은 대조구에 비해 20% 높게 나타났다. Salmonella thyphimurium YG 1024의 복귀돌연변이 콜로니수를 조사한 결과 복음치커리 물추출물 (10~5,000 μ/g)의 처리구에서는 돌연변이를 유발시키지 않았으며, 2-aminofluorene을 처리한 양성 대조군에 물추출물을 plate당 1,000~5,000 μ/g 농도로 처리한 결과 돌연변이 억제 활성은 없었다.
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 5 mM 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 decreased by the administration of chicory extract (800 mg/kg). Chicory water extract (800 mg/kg) 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 μ/g per plate. Water extract of roasted chicory did not inhibit the mutagencities of Salmonella thyphimurium YG 1024 induced by 2-aminofluorene.
