HE You-cheng · Ion Exchange and Adsorption · 2007
This study aims to find an optional technological process for extracting artemisinin by macroporous resins. The technological condition was confirmed by observing the indexes of the adsorption capacity, content, product yield and Extraction rate of artemisinin. Results showed that ADS-17 resin has big adsorption capacity for artemisinin and is easy for desorption, it can be used in the technological process of extracting artemisinin from Artemisia annua. The technological condition as the following: the maximum adsorption capacity is 112.30mg/mL, the flow rate of adsorption is 2BV/h, the elution is 90% ethanol, the flow rate of desorption is 2BV/h, the quantity of artemisinin is more than 99%, the product yield of artemisinin is above 0.30%, and Extraction rate of artemisinin is above 75%.
