Evaluation of In-vitro Anticoagulation Activity of 33 Different Medicinal Herbs

Hee-Young Ryu; Seon Mi Ahn; Jong-Sik Kim; Ho-Yong Sohn

한방 생약재로부터 안전하면서도 신규의 항혈전제를 개발하기 위해, 현재 국내에서 유통되고 있는 국내 및 국외산 한방 생약재 33종을 대상으로 40종의 에탄올 추출물을 조제하고, 이들의 thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (aPTT)을 평가하였다. 생약재중 중국산은 28종으로 대부분이 국외산이었으며, 부위별로는 종자 및 뿌리 부위가 19종을 차지하였다. 평균 수분함량은

농도에서도 용혈활성이 없음을 확인하여 이들 4종을 최종 선정하였다. 본 연구결과는 이미 대량생산이 확립된 한방생약제로부터 우수한 항혈전제 개발이 가능함을 제시하고 있으며, 트롬빈 및 혈장 응고 인자에 대한 특이 저해제 개발이 가능함을 제시하고 있다. 【This study was carried out to develop safe and novel anticoagulation agents from oriental medicinal herbs. From 33 medicinal herbs, 40 different ethanol extracts were prepared according to place of origin or extraction parts, and anticoagulation activities were evaluated by determination of thrombin time (TT), prothrombin time (PT) and activated partial thromboplastin time (aPTT). The average water content and average extraction ratio for the medicinal herbs were
