The inhibitory activities of a water extract of Sanghwang mushroom(Phellinus linteusau)(SWE) against α-glucosidases were evaluated in this study. Inhibiting these enzymes involved in the absorption of disaccharides significantly decreases the postprandial increase in blood glucose level after a mixed carbohydrate diet. Oxygen radical absorbance capacity and 1, 1-diphenyl-2-picryl hydrazyl scavenging activities of the SWE were evaluated to investigate the antioxidant activity of the SWE associated with complications of long-term diabetes. Furthermore, the postprandial blood glucose lowering effect of SWE was compared to a known type 2 diabetes drug(Acarbose®) in a Sprague-Dawley rat model. SWE significantly reduced the blood glucose increase after sucrose loading. These results suggest that SWE, which has high α-glucosidase inhibitory activity and high antioxidant activities, has the potential to contribute to a useful dietary strategy for controlling postprandial hyperglycemia.

본 연구에서는 야생에서 분리한 눈꽃동충하초균의 배양적 특성을 알아보기 위해 배양특성 시험을 수행하였다. , 습도 60%에서 눈꽃동충하초균을 고체배양한 결과 초기 균사의 직경 12 mm에서 4일차에 균사체 직경이 36 mm 이었으며, 배양 5일차부터 급격한 균사신장이 일어나다가 8일차 이후부터는 생육속도가 서서히 감소되는 경향을 보였다. PDB 액체배지에서 종균배양의 상태와 생육도를 검토한 결과, PMV가 배양일차에 따라 1일차에 1%, 3일차에
