Study on extraction technology of Fuyuan Xingnao granule / 药学实践杂志

ABSTRACT

Objective To study the extraction technology and optimize the extraction process of Fuyuan Xingnao gran-ule.Methods The preliminary extraction process was designed by routine extraction method combined with the results of pharmacological activity experiment.The extraction process was optimized with orthogonal test.Results The extract was ob-tained by ethanol reflux extraction,water decoction extraction or ethanol precipitation followed by filtration and concentration. The optimal process for ethanol reflux extraction was extracting twice with 50% ethanol.The ratio of liquor to dry material was 8∶1 for the first time and 6∶1 for the second time.The extraction time was 120 minutes for the first time and 80 minutes for the second time.The optimal process for water decoction extraction was extracting twice with 120 minutes and 80 minutes each time.The ratio of liquor to dry material was 10∶1 for the first time and 8∶1 for the second time.The extraction temper-ature was100 ℃.The best ethanol precipitation process was 16 hour extraction with 80% ethanol.The ratio of ethanol to dry material was 2∶1.Conclusion The quality of Fuyuan Xingnao granule extract with this optimized extraction process was in line with requirements of Pharmacopoeiaof the People's Republic of China 2015,4 Volumes(0104 granule).
