Abstract

Biological activities of enzymatic hydrolysate of spirulina (EHS) were investigated. EHS showed no significant effects on the growth-stimulating activity for lactic-acid bacteria and antioxidant activity. EHS showed slight in vitro growth-inhibitory effects (15% at 1.42 mg/L) on a human cervical cancer cell line (HeLa). In addition, the anticoagulant activities of EHS were measured based on three different pathways: common, intrinsic and extrinsic pathways. As an indication of anticoagulant activity on common pathway, thrombin time (TT) of EHS (100 mg/L) was measured as 155.6 sec. Activated partial thromboplastin time (aPTT) for intrinsic pathway of EHS (1,000 mg/L) was measured as 95.8 sec. Prothrombin time (PT) based on extrinsic pathway of EHS (1,000 mg/L) was measured as 10.6 sec. These data showed that EHS have influences on anticoagulant factors of common pathway and intrinsic pathway. Consequently it was found that EHS could be used as a functional food for blood circulation.

스피루리나를 세포벽 가수분해효소와 단백질 가수분해효소로 처리하여 조제한 스피루리나 가수분해물(enzymatic hydrolysate of spirulina, EHS)의 생리활성을 조사하였다. 효소처리 가수분해물의 유산균 증식효과, 항산화능, 암세포 증식저해 활성, 항혈전 활성을 분석한 결과 EHS는 유산균 증식활성과 항산화능에 큰 영향을 미치지 않았으며, 자궁경부암세포(HeLa)에 대해 1.42 mg/L의 농도에서 15% 미만의 증식저해효과를 나타내었다. 반면 항혈전 활성을 공통 경로(common pathway), 내인성 경로(intrinsic pathway), 외인성 경로(extrinsic pathway)로 구분하여 측정한 결과, 공통경로, 내인성 경로와 유사한 항혈전 활성이 있음을 확인하였다. 공통 경로를 thrombin time assay로 측정한 결과 EHS의 농도가 100 mg/L일 때 155.6초를 나타내었다. 내인성 경로는 activated partial thromboplastin time assay로 측정하였고, EHS의 농도가 1000 mg/L일 때 95.8초를 나타내었다. 외인성 경로를 prothrombin time assay로 측정한 결과 EHS의 농도가 1000 mg/L일 때 10.6초를 나타내었다. 결과적으로 스피루리나 효소가수분해물(EHS)이 항혈전경로 중 공통경로와 내인성 경로에 활성이 있음을 알 수 있었으며, 이를 토대로 신규의 항혈전 기능성 원료로 개발될 수 있을 것으로기대된다.
