几年来,我们用煤油法制备草乌注射液,取得了一定成绩,现介绍如下:一、草乌总碱的提取工艺草乌粗粉用4%氢氧化钠或碳酸钠溶液充分湿润,拌匀,放置2小时以上(使草乌粗粉充分碱化)→碱化草乌粗粉阴干后,装入自制渗滤装置(无渗滤装置时,也可以用浸泡的方法),用市售煤油浸泡24小时后开始渗滤(流速控制在每分钟50～60滴),至提
Over the past few years, we have used kerosene method to prepare Kuowu injection, and achieved certain results. Now we introduce the following: First, the extraction process of total alkaloids from Sophora arbutus Kudzu powder is fully wetted with 4% sodium hydroxide or sodium carbonate solution, and mix well. , Place it for more than 2 hours (make turfgrass coarse enough to alkalinize) → alkalinize turfgrass coarse powder and dry it, then put it into self-made percolation device (without percolation device, you can also use soaking method), use commercial kerosene After 24 hours of soaking, percolation starts (the flow rate is controlled at 50-60 drops per minute).
