Anticancer Activities of the Extract from the Mycelia of Coriolus versicolor

운지버섯 균사체 추출물의 항암효과에 관한 연구

An anticancer substance was prepared by ethanol precipitation of the hot water extract of culture mycelia of Conolus versicolor KFCC 30388. After 6 days of fermentation, the mycelia growth reached the peak and reducing sugar consumed almost all. HTCFA method has been employed for three human cancer cell lines, Hep-2(larynx cell), A-427 and Calu-3 (lung cell). Anticancer activities in A-427 and Calu-3 were 8.4 and 9.8% survival rate, respectively. The chemical analysis of the extract from the mycelia showed 42.2% of polysaccharide and 10.5% of protein. The polysaccharide consisted of five kinds of monosaccharides, L-glucose, D-glucose, galactose, mannose and xylose.

Coriolus versicolor KFCC 30388 균을 액체배양하여 배양 6일째 균사체 생성이 가장 우수하였으며, 건조 균사체량은 17.2g/l을 얻었다. 균사체들로부터 항암성 단백다당체를 분리하여 in vitro에서 plate assay 방법으로 human cancer cell lines 3종에 대한 항암성을 조사한 결과, 0.1mg/ml의 survival rate를 나타내어 항암성을 확인하였다.화학적 분석 결과 단벡다당체는 polysaccharide 42.2%, protein 10.5%로 이루어졌으며, 구성 단당류는 D-glucese, L-glucese, galatose, mannose, xylose 등 으로 되어 있었다.
