초록

대추 추출물에서 fibrin을 가수분해 하는 생리활성 물질이 존재함을 알고 이 추출물의 열과 산에 대한 안정성 및 그 특징을 조사 하였다. Fibrin plate method 를 사용하여 측정된 fibrinolytic activity 는 대추 추출물의 첨가량이 증가할수록 높았으며, 이 추출물은 $100^{\circ}C$ 에서 10분간 열처리시에 안정한것으로 나타났다. 또한 pH 2.0, 3.0, 4.0 에서 3시간 보관후 fibrinolytic activity 를 측정한 결과 control의 80% 이상의 활성을 나타내었다. 한편 투석후 (분자량 12,000) 에는 활성이 나타나지 않았으며, 이는 대추에서 추출한 fibrin 분해 생리활성 물질이 분자량이 낮은 저분자 물질임을 알 수 있었다.

Crude extract prepared from jujube (Zizyphus mauritiana) possseses fibrinolytic activity hydrolyzing fibrin. A clear transparent region is observed where fibrin is hydrolyzed, and its diameter increased as the added jujube extract increased. The fibrinolytic activity of jujube extract seems to be heat and acid stable since its activity was retained after heat treatment at $100^{\circ}C$ for 10 min or an acid treatment by incubating at pH 2.0, 3.0, and 4.0 for 3 hours. But the jujube extract dialyzed with a cellulose membrane with molecular weight cutoff of 12,000 and 2,000 lost its activity, which suggests the fibrinolytic activity might be compounds of low molecular weight.
