一、工艺洋金花干品粗粉,置渗漉筒中,稍加压匀,加入75％乙醇超过药面浸煮12～24小时,开始渗漉,流速开始每分钟8毫克左右,收集漉液约相当于初投入乙醇的量,另器保存继续渗漉,流速为每分钟31毫升,至生物硷提尽,渗漉液回收乙醇,存约1/10量时再把最初收集的渗漉液加入,继续回收乙醇,存留液水浴浓缩成膏状,加入预先用盐酸调节 PH2的蒸馏水稀释溶解,过滤,滤液加氯仿分次振摇(第一次氯仿为溶液的1/3,第二次为1/4,第三次为1/5),分离出氯仿。酸液滴加浓氨水调至 PH9,加氯仿提取(第一为溶液的1/2,第二次为1/3……等),至生物硷提尽。氯仿提取液,加蒸馏水适量洗涤一次。回收氯仿,存留液置水浴上浓缩至膏状物,
First, the process Yang Jinhua dry coarse powder, placed in the infiltration tube, a little pressure evenly, adding 75% ethanol over the drug surface digestion for 12 to 24 hours, began to percolate, the flow rate began to 8 mg per minute, collecting phlegm It is equivalent to the initial amount of ethanol, the other device is preserved for continued percolation, the flow rate is 31 ml per minute, and the bioreactor is used up. The osmotic solution recovers ethanol, and the first collected osmotic fluid is stored when the amount is about 1/10. Add, continue to recover the ethanol, the retention liquid bath is condensed into a paste, diluted with distilled water adjusted with PH2 in advance with hydrochloric acid, dissolved, filtered, and the filtrate is shaken with chloroform in several portions (the first time chloroform is 1/3 of the solution, and the second is 1/4, third time 1/5) Chloroform was isolated. Acid droplets were added to concentrated ammonia and adjusted to PH9. Chloroform extraction (1/2 for the first solution, 1/3 for the second solution, etc.) was performed. The chloroform extract was washed once with distilled water. Chloroform is recovered, and the liquid is kept on a water bath and concentrated to a paste.
