The invention provides a preparation method of Astragalus invigorating stomach ointment, which can reduce volatilization of volatile oil and ensure pharmacodynamics. The preparation method comprises the following steps: (1) extracting volatile oil with water vapor from ginger and cinnamon twigs; collecting and reserving the distilled water solution; (2) weighing HP_beta_CD powder of 10_13 times the quality of the volatile oil, adding distilled water and grinding at one time, slowly dropping 50% volatile oil anhydrous ethanol solution, and grinding at the same time, making cyclodextrin inclusion compound after vacuum drying; (3) medicines in step (1) The residue was decocted twice with four flavors of Astragalus membranaceus, Paeonia alba, licorice and jujube in water for 2 hours each time. The decoction was merged with the distilled water solution, filtered, and the filtrate was stationary. The supernatant was poured into the thick paste with a relative density of 1.18 1.20 when concentrated at 80 C. Fourthly, the bait sugar 814g was added into the syrup, the thick paste was stirred, then concentrated to a certain amount, and added sodium benzoate 3G and steps to cool. Su 2 cyclodextrin inclusion compound was stirred to make 1000g decoction.

一种黄芪健胃膏的制备方法
本专利技术涉及中药制备
,具体涉及一种黄芪健胃膏的制备方法。
技术介绍
黄芪健胃膏由黄芪、桂枝、甘草、白芍、生姜、大枣组成,具有补气温中,缓急止痛的功效,是一种常用的中成药。黄芪健胃膏的处方和标准制备工艺于《中国药典》2015版中有详细介绍。这种标准制备工艺中,生姜、桂枝用水蒸气提取的挥发油,是直接加入在稠膏中,再加上搅拌过程,容易造成挥发油过度挥发,且氧化变质,影响疗效。
技术实现思路
本专利技术的目的是提出一种黄芪健胃膏的制备方法,可以减少挥发油的挥发,保证药效。根据本专利技术提供的黄芪健胃膏的制备方法,所述黄芪健胃膏的中药处方为:黄芪407g,白芍244g,桂枝122g,生姜122g,甘草122g,大枣122g;所述制备方法包括以下步骤:①、生姜、桂枝用水蒸气提取挥发油;蒸馏后的水溶液收集备用;②、称取8-10倍所述挥发油质量的HP-β-CD粉末,加入蒸馏水并一次研磨,缓慢滴加50%挥发油无水乙醇溶液,同时二次研磨,经真空干燥后制成环糊精包合物;③、步骤①的药渣与黄芪、白芍、甘草、大枣四味加水煎煮二次,每次2小时,合并煎液并与蒸馏 ...
