Abstract

To investigate the bio-activities of lotus (Nelumbo nucifera Gaertner), ethanol extracts were prepared from different parts of lotus, including lotus root, node of root (NR), leaf, pod of seed (PS), seed (S), and embryo of seed (ES), respectively. Anti-thrombosis activities were evaluated. NR, S, and PS extracts displayed strong anti-coagulation activities, as evidenced by the inhibition of thrombin, prothrombin, and coagulation factors, respectively. NR, leaf, S, and PS extracts displayed strong platelet aggregation inhibitory activities. The aggregation inhibition of S and PS extract was comparable to that of aspirin. The extracts of NR, S, and PS did not show hemolysis activity up to 1.0 mg/ml.

연(Nelumbo nucifera Gaertner)으로부터 신규의 유용 생리활성을 확인하기 위해, 연잎, 연자방, 연자육, 연자심, 우절 및 연근으로부터 각각 ethanol 추출물을 제조하고, 현재까지 보고되지 않은 항혈전 활성을 평가하였다. 그 결과, 연근, 연잎 및 연자심 추출물은 항응고 활성이 인정되지 않았으나, 우절, 연자방 및 연자육 추출물에서는 강력한 TT, PT, aPTT 연장효과를 나타내었으며, aspirin 보다 강력한 항응고 활성을 나타내었다. 또한 혈소판 응집저해 활성 평가 결과, 우절, 연잎, 연자방, 연자육 추출물에서 응집저해가 나타났으며, 가장 강력한 응집저해는 연자방과 연자육에서 확인된 바, 이는 아스피린에 필적하는 강력한 활성이었다. 상기 활성 추출물은 1.0 mg/ml 농도까지 인간 적혈구 용혈활성이 없음을 확인하여, 우절, 연자방 및 연자육 추출물이 신규의 항혈전제로 사용 가능함을 제시하였다.
