Description

一种兽用清热解毒口服液的制备方法
技术领域
本发明属于兽用中药口服液制备技术领域,具体涉及一种兽用清热解毒口服液的制备方法。
背景技术
清瘟解毒口服液是收录在《兽药质量标准》(中国农业出版社,2017版) 中的一种畜禽用中药口服液,主要成分为地黄、栀子、黄芩、连翘、玄参、板蓝根;本品主要功效清热解毒,主治外感发热;《兽药质量标准》对清瘟解毒口服液的制备方法为:以制备1000ml口服液为例,将地黄150g、栀子250g、黄芩225g、连翘200g、玄参150g、板蓝根200g共计6味,加水煎煮两次,合并煎液,静置,滤过,浓缩,加适量苯甲酸钠,加水调至1000ml,灌装,灭菌,既得;但是这种利用传统的煎煮工艺和传统的配方制备的清瘟解毒口服液存在有效成分含量低,药效不够显著的缺陷;因此,如何创新和改进清瘟口服液的配方,并且转变传统制备工艺,将二氧化碳超临界萃取技术提取应用于制备清瘟口服液,并提高其提取效率,成为了目前亟待解决的技术问题。
发明内容
本发明的目的是为了克服现有技术的不足,而提供一种提取率高、无有机溶剂残留和工艺简单的一种清热解毒口服液的制备方法。
本发明的目的是这样实现的:一种兽用清热解毒口服液的制备方法,清热解毒口服液的配方为:取黄连150—200g、地黄100—200g、黄柏 200—250g、栀子200-250g、黄芩200—300g、连翘200—250g、玄参150—200g、板蓝根200—250g制备而成;制备方法是二氧化碳超临界萃取釜中,加入70%乙醇作为夹带剂,萃取时间为5—7个小时,萃取温度为46—50℃,压力为20—25Mpa,然后升温进行乙醇回收,得提取物浸膏,加入一定量的纯化水,过滤得口服液原液,随后进行灌装、灭菌既得。
其制备方法的具体步骤为:
(1)取黄连150—200g、地黄100—200g、黄柏200—250g、栀子 200-250g、黄芩200—300g、连翘200—250g、玄参150—200g、板蓝根 200—250g;
(2)将上述药材进行粉碎后过60目筛得到混合物,将混合物放置于二氧化碳超临界萃取釜中;
(3)在萃取釜加入70%的乙醇作为夹带剂,萃取时间为5—7个小时,萃取温度为46—50℃,压力为20—25Mpa;
(4)待萃取完成后,升温回收乙醇,得混合物提取浸膏,加入一定量的纯化水,密度不低于1.04,并调配PH值为4.3—6.0,并进行过滤;
(5)将过滤后的提取液进行灌装、灭菌即得。
所述步骤(4)中过滤所使用滤芯为的为PP折叠滤芯,过滤孔径为0.44 μm。
所述步骤(4)中PH值调节试剂为柠檬酸或稀盐酸。
所述清热解毒口服液的配方为:取黄连160g、地黄150g、黄柏220g、栀子220g、黄芩250g、连翘200g、玄参170g、板蓝根250g。
所述清热解毒口服液的配方为:取黄连200g、地黄150g、黄柏200g、栀子200g、黄芩240g、连翘200g、玄参180g、板蓝根230g。
所述清热解毒口服液的配方为:取黄连180g、地黄130g、黄柏220g、栀子250g、黄芩270g、连翘220g、玄参200g、板蓝根250g。
本发明的有益效果是:本发明采用二氧化碳超临界萃取釜进行反应,与传统方法相比,具有提取率高、操作温度低、中药有效成分不被破坏、无有机溶剂残留和工艺简单的优点;乙醇是一种良好的有机溶剂,与被萃取物亲和性较强,是一种良好的夹带剂,不仅可以增加溶质在超临界流体中的溶解度和选择性,同时还可以作为助表面活性剂有利于超临界流体微乳液的形成;本发明能将原料组分有效成分完全提取出来,步骤简单,节约了成本,本申请具有提取率高、操作温度低、中药有效成分不被破坏、无有机溶剂残留和工艺简单的优点。
