在生产穿心莲时,采用65%乙醇回流提取,其出膏率、于浸膏中内酯含量均比《中国药典》85年版用85%乙醇回流提取高,并能克服在生产过程中出现的“抓锅”、结块”等现象。表中数据为三次实验的平均值。实验说明采用低浓度乙醇提取时,可使树酯的溶出率降低,从而克服了“抓锅”“结块”等现象。出膏率随乙醇浓度降
In the production of Andrographis paniculata, using 65% ethanol reflux extraction, the paste rate, lactone content in the extract than the “Chinese Pharmacopoeia” 85 years with 85% ethanol reflux extraction, and can overcome the emergence of the production process " The phenomenon of “potting”, agglomeration, etc. The data in the table is the average of three experiments.Experiment shows that when using low-concentration ethanol, the dissolution rate of the resin can be reduced, thus overcoming the “gripping” and “caking” etc. Phenomenon: The paste rate decreases with ethanol concentration
