Title: Research of extract methods of rhizoma optidis
Abstract: Objective To ascertain the factors and levels in the best methods by the research of the extract methods of Rhizoma Coptidis.Methods The water was compared with 50% alcohol extraction,and the optimum extraction solvent was chose.The orthogonal design was used to select the optimum extraction process according to the contents of inspection,extraction time,immerse time,tile volume of solvent and the number of extraction times.Results The optimum extraction process was as follows:12,10,10 times amount of water was added,and they were refluxed and extracted for 3 times,the extraction time was 1.5,1.5 and 1 hour.Conclusion It can offer a basis on manufacture in the factory by selection of the optimum extraction process.
