Description
技术领域
本发明涉及2型糖尿病药物技术领域,具体涉及一种治疗2型糖尿病的中药组合物及其制备方法。
背景技术
糖尿病是一种以高血糖为主要特征的慢性代谢性疾病。通常认为其发病机制与胰岛素分泌不足和/或胰岛抵抗相关。糖尿病主要分为1型糖尿病、2型糖尿病和其他类型糖尿病,其中2型糖尿病患者占患病人数的95%以上。中国是糖尿病患病率最高的国家之一,患病总人数已经达到9240万,糖尿病也已成为继肿瘤、心血管疾病之后严重危害我国人群健康的疾病之一。
发明内容
本发明的目的是提供一种治疗2型糖尿病的中药组合物及其制备方法,以用于改善和治疗2型糖尿病病症。
本发明为解决技术问题所采用的技术方案如下:
本发明的一种治疗2型糖尿病的中药组合物,按照重量份数计包括以下组分:
托盘根1-10份、桑叶5-10份、葛根5-10份、薏米1-10份、山药1-10份。
作为优选的实施方式,本发明的一种治疗2型糖尿病的中药组合物,按照重量份数计包括以下组分:托盘根5份、桑叶7份、葛根7份、薏米5份、山药5份。
本发明的一种治疗2型糖尿病的中药组合物的制备方法,包括以下步骤:
称取托盘根1-10份、桑叶5-10份、葛根5-10份、薏米1-10份、山药1-10份,加入5-10倍水煎煮30-60min,提取、滤过,将滤液浓缩至相对密度1.25-1.35、80℃,得到水提物;
将上述水提物加入1.5-2.5倍量乙醇,4℃醇沉10-14小时,滤过,将滤液减压蒸馏除去乙醇,浓缩至稠膏,真空冷冻干燥,粉碎,即得。
作为优选的实施方式,本发明的一种治疗2型糖尿病的中药组合物的制备方法,包括以下步骤:
称取托盘根5份、桑叶7份、葛根7份、薏米5份、山药5份,加入7.5倍水煎煮45min,提取、滤过,将滤液浓缩至相对密度1.25-1.35、80℃,得到水提物;
将上述水提物加入2倍量乙醇,4℃醇沉12小时,滤过,将滤液减压蒸馏除去乙醇,浓缩至稠膏,真空冷冻干燥,粉碎,即得。
本发明的有益效果是:
本发明的一种治疗2型糖尿病的中药组合物,主要由托盘根、桑叶、葛根、薏米、山药组成。其中,各物质在本发明中所起的作用或各物质相互之间的协同作用如下:
在本发明中,托盘根主要起到祛风利湿和抗氧化作用。
在本发明中,桑叶含有的生物碱和多糖可促进细胞分泌胰岛素;含有的蜕皮甾酮可促进葡萄糖转变为糖元。
在本发明中,葛根能生津止渴,含有的葛根素具有降血糖作用。

2、动物分组给药
成模小鼠按血糖随机分为4组:模型组、中药组合物低剂量组、中药组合物中剂量组和中药组合物高剂量组,每日灌胃给药剂量见表1。
表1
组别 | 试剂和剂量 |
正常组 | 0.9%生理盐水、1ml |
模型组 | 0.9%生理盐水、1ml |
中药组合物低剂量组 | 中药组合物、2mg/kg |
中药组合物中剂量组 | 中药组合物、4mg/kg |
中药组合物高剂量组 | 中药组合物、8mg/kg |
3、空腹血糖实验
实验开始后,每天在同一个时间给药一次,连续6周。实验结束后检测各组小鼠空腹12h血糖值,检测结果如表2所示,其中中药组合物各组均能够显著降低2型糖尿病小鼠空腹血糖值,其中中药组合物高、中剂量组小鼠经过6周治疗后血糖值恢复到正常范围以内,由此说明本发明的中药组合物有较好的中药效果,能够用于治疗2型糖尿病。
表2
组别 | 空腹血糖值(mmol/ml) |
正常组 | 4.72±0.34 |
模型组 | 12.92±0.69<sup>##</sup> |
中药组合物低剂量组 | 7.99±0.48** |
中药组合物中剂量组 | 5.62±0.57** |
中药组合物高剂量组 | 5.22±0.68** |
表2中,模型组与正常组比较,##P<0.01;中药组合物各组与模型组比较,*P<0.05,**P<0.01。
4、糖耐量实验
实验第6周末,将小鼠禁食12h后,灌胃给予20%葡萄糖2g/kg(每1kg体重的小鼠给予2g葡萄糖);用罗氏血糖仪分别测定空腹及服糖后30、60、90及120min的血糖含量,检测结果如表3所示,中药组合物各剂量组效果显著,由此说明本发明的中药组合物具有很好的改善2型糖尿病的作用,,能够用于治疗2型糖尿病。
