Study the Process of Extraction, Concentration and Drying of Yunpi Granules
Objective:To optimize the extraction,concentration and drying process of Yunpi granules.Methods:The extraction technique was selected by orthogonal method,taking the contents of Naringin,hesperidin,atractylodin,extract yield,compound essential oil as comprehensive evaluation index.Chose three factors of amount of water added,length of decocting time and frequencies of decocting to study their effect on extraction and optimized the process of concentrate and drying based on the extract fluidity and quality of dry extract product.Results:The best extracting technology of Yunpi Granule was defined as follows:soaking 1.5h,water extracting for 3 times with 5h,1.5h,and 1h each time,and adding 6 times the amount of water to the medicinal herbs.The optimal concentrated and dry conditions was as follows-0.06-0.08Mpa,70℃ concentrated,and 80℃ drying.Conclusion:The extraction,concentration and drying process of Yunpi granules is stable and feasible with reliable and reasonable evaluation index.
