Description

一种兽用桑仁清肺口服液的制备方法
技术领域
本发明属于兽用中药口服液制备技术领域,具体涉及一种兽用桑仁清肺口服液的制备方法。
背景技术
桑仁清肺口服液是收录在《兽药国家标准汇编——兽药地方标准上升国家标准》第三册,(中国农业出版社,2012年7月第1版)中的一种畜禽用中药口服液,其处方为:桑白皮100g,知母80g,苦杏仁80g,前胡100g,石膏120g,连翘120g,枇杷叶60g,海浮石40g,甘草60g,橘红100g,黄芩140g;本品清肺,止咳,平喘,主治肺热咳喘,临床上主要用于鸡外感风热或感冒化热引起的肺热咳喘证。
目前,《兽药国家标准汇编——兽药地方标准上升国家标准》第三册对桑仁清肺口服液的制备方法为: 以制备1000ml药液为例,桑白皮100g,知母80g,苦杏仁80g,前胡100g,石膏120g,连翘120g,枇杷叶60g,海浮石40g,甘草60g,橘红100g,黄芩140g,以上11味,加水煎煮两次,合并煎液,滤过,滤液减压浓缩至相对密度为1.02(80℃),冷藏24小时,滤过,滤液加苯甲酸钠适量,加水至1000ml,搅匀,分装,灭菌即得。
中草药成分复杂,有活性成分,也有如蛋白质、果胶、淀粉、植物纤维等非活性成分,这些成分一方面影响植物细胞中活性成分的浸出,另一方面也影响中药液体制剂的澄清度。传统提取方法提取温度高,收率低,成本高,消耗大量溶剂,生产污染物排放多;根据酶具有催化效率高,作用专一性强和催化条件温和等特点,采用酶解提取可以较温和地将植物组织分解,加速有效成分的释放提取,可以较大幅度地提高有效成分的收率,同时可以提高生产效率,降低能耗,改善劳动条件,减少污染。
发明内容
本发明旨在提供一种生产效率高、能耗低、污染小、绿色不添加任何防腐剂的兽用桑仁清肺口服液的制备方法。
为实现上述目的,本发明采取的技术方案如下:
一种兽用桑仁清肺口服液的制备方法,每1000ml口服液,所采用的药材原料组成为:桑白皮100g、知母80g、苦杏仁80g、前胡100g、石膏120g、连翘120g、枇杷叶60g、海浮石40g、甘草60g、橘红100g、黄芩140g,其特别之处在于,1000ml口服液的制备方法包括如下步骤:
