Abstract
具有抗血栓作用的广西莪术提取物的应用,该提取物是指从广西莪术,拉丁学名为Curcuma kwangsiensis S.G.Lee et C.F.Liang的干燥根茎中提取分离得到的广西莪术大孔吸附树脂体积浓度为50%的乙醇洗脱部位提取物及大孔吸附树脂体积浓度为70%的乙醇洗脱部位提取物,并将这两种提取物应用于制备治疗抗血栓的药物;而这两种提取物可明显抑制胶原蛋白‑肾上腺素诱发的小鼠体内血栓形成,降低动物死亡和偏瘫数,提高恢复数;明显减轻大鼠体内静脉血栓湿重;明显延长电刺激致大鼠颈总动脉血栓形成时间;明显减轻大鼠动静脉旁路血栓湿重;具有明显的抗血栓作用,可用于血栓性疾病的治疗。
Description
技术领域
本发明涉及医药技术领域,尤其涉及中药提取物,具体涉及具有抗血栓作用的广西莪术提取物的应用。
背景技术
血栓性疾病严重威胁人类健康和生命,冠心病、心绞痛、脑中风、心肌梗死等血栓性疾病发病率、致残率和致死率都很高,且近年来,血栓性栓塞引起的疾病发病率逐渐增加,造成病患者生活质量下降,劳动力丧失致残,严重阻碍了经济发展与人民生活水平的进一步提高。从中药中应用具有良好抗血栓作用的中药及其提取物,用于防治血栓性疾病。
广西莪术为姜科植物广西莪术(Curcuma kwangsiensis S. G. Lee et C. F. Liang)的干燥根茎,性味辛、苦、温,具有行气破血,消积止痛之功效,在广西、云南、四川、福建等地有分布,在广西主产于钦州、南宁、大新、贵港、上思等地,是广西地道药材,做为中药莪术使用,在广西已大量人工栽培种植成功,为广西大宗药材,广西民间广泛用于瘀血经闭、食积胀痛、跌打损伤等。
广西莪术主要含桉油精、樟脑、异龙脑、莪术烯等30余种挥发油成分及姜黄素类、吉马酮、β-谷甾醇、羽扇豆醇等化学成分,现代药理研究表明,广西莪术具有抗肿瘤、抗病毒、抗菌、抗炎、抗溃疡等药理作用。
发明内容
本发明的目的是从广西莪术(Curcuma kwangsiensis S. G. Lee et C. F. Liang)的干燥根茎中提取分离得到的广西莪术提取物,而该提取物具有抗血栓方面的用途,用于治疗血栓性疾病,为血栓性疾病患者带来福音。
本发明通过如下技术方案解决上述技术问题。
广西莪术药材用水提取,提取液浓缩后,80℃烘干得干膏,上聚苯乙烯型大孔吸附树脂柱,依次用蒸馏水、体积浓度为30%的乙醇、体积浓度为50%的乙醇、体积浓度为70%的乙醇、体积浓度为90%的乙醇进行梯度洗脱,分别收集各洗脱部位液体,减压浓缩,真空干燥,得水洗脱部位、体积浓度为30%乙醇洗脱部位、体积浓度为50%乙醇洗脱部位、体积浓度为70%乙醇洗脱部位、体积浓度为90%乙醇洗脱部位。
以对胶原蛋白-肾上腺素诱发小鼠体内血栓形成的影响试验,对大鼠体内静脉血栓形成的影响试验,对电刺激致大鼠颈总动脉血栓形成的影响试验,对大鼠动静脉旁路血栓形成的影响试验为抗血栓作用药效学指标,进行抗血栓作用药效学评价,结果发现,广西莪术大孔吸附树脂体积浓度为50%乙醇洗脱部位和大孔吸附树脂体积浓度为70%乙醇洗脱部位具有很好的抗血栓作用,用于制备治疗血栓性疾病的抗血栓方面的药物。
