Huangqi extract extraction and concentration equipment, Huangqi is extracted with water, which is better than ethanol extraction. Huangqi is decocted three times with water and extracted three times with ethanol reflux. Based on the content of Huangqi glycoside IV, the extraction rate can reach over 70%. However, during water extraction and alcohol precipitation, the loss of glycoside IV is small. After three rounds of alcohol precipitation separation and purification, the Huangqi glycoside extract (intermediate) has high purity, and the injection made from it is very clear and does not produce precipitation after long-term storage. However, during alcohol extraction and water precipitation, not only is the loss of glycoside IV large, but it is also difficult to remove all fat soluble components. The purity of the Huangqi glycoside extract (intermediate) obtained is low, and the injection made from it will produce precipitation after storage;
Huangqi extract extraction and concentration equipmentHuangqi is purified by water extraction and alcohol precipitation, which can simultaneously extract Huangqi saponins, Huangqi flavonoids, and polysaccharide active ingredients. Through alcohol precipitation, polysaccharides can be separated from the aforementioned two types of active ingredients.
The optimal process is to extract 3 times with 60% ethanol as the solvent and 12,10,10 times the amount of reagents used, each extraction lasting 1.5 hours.
