川牛膝不同组分体内抗凝血活性研究

         

摘要

目的:研究川牛膝不同浓度乙醇提取的粗多糖在体内的抗凝血活性.方法:用50%乙醇、20%乙醇、水为溶剂回流提取,乙醇醇沉,终浓度80%,沉淀出粗多糖,小鼠连续3 d灌胃给予高、中、低剂量川牛膝不同提取物沉淀的粗多糖,测定全凝血时间(CT)、出血时间(BT)、凝血酶原时间(PT)、凝血酶时间(TT)、活化的部分凝血活酶时间(APTT)和纤维蛋白原(FIB).结果:川牛膝水提粗多糖和20%乙醇提取粗多糖能显著延长CT、BT、APTT和TT,降低FIB值(P<0.05),而对PT无明显的影响.而50%乙醇提取粗多糖对CT、BT、PT、APTT、TT延长作用不明显,且FIB值无变化.结论:川牛膝水提取粗多糖具有显著的体内抗凝血活性.20%乙醇提取粗多糖对体内抗凝血活性不如水提取粗多糖.50%乙醇提取粗多糖在体内无明显抗凝血活性.多糖有可能是体内抗凝血的活性成分,并通过内源性凝血途径和共同凝血途径发挥抗凝血作用,但是否是抗凝血的活性成分还有待进一步研究.%Objective: To study the anticoagulant activity of the extraction from Radix Cyathulae by different ethanol concentrations. Methods: Solvent reflux extraction and alcohol precipitation were applied with water, 20% ethanol, and 50% ethanol, the final concentration was 80%, crude polysaccharides were precipitated. Different concentrations of the crude polysaccharides were administrated to the mice for three continuous days. Afterwards, whole blood coagulation time(CT), bleeding time (BT), prothrombin time(PT), thrombin time(TT), activated partial thromboplastin time (APTT), and fibrinogen (FIB) were tested. Results: The crude polysaccharides extracted by water and by 20% ethanol could significantly prolong CT, BT, APTT and TT time(P <0.05), they could reduce FIB value, but had no obvious effect on PT. However, the crude polysaccharides extracted by 50% ethanol had no significant effect on the prolongation of CT, BT, PT, APTT, and TT, it did not decrease the FIB value. Conclusion: The crude polysaccharides of Radix Cyathulae extracted by water has significant anticoagulant activity in vivo. Anticoagulant activity of 20% ethanol extract is secondary to water extract in vivo. 50% ethanol extract has no significant anticoagulant activity in vivo. Polysaccharides may be the active ingredients of anticoagulation in vivo, they play the anticoagulant role through the intrinsic coagulation pathway and the common coagulation pathway. However, whether polysaccharides are anticoagulant active ingredients needs to be further studied.
