ABSTRACT
OBJECTIVE:To optimize the precipitation process of the extract of Folium Isatidis using chitosan and ZTC1+ 1-Ⅱ natural clarify agents.METHODS:Using the remaining rates of polysaccharide and indirubin and the defecation level as indexes,the optimum process of removing impurity was investigated with single-factor test.RESULTS:The optimum process conditions were as follows:chitosan:precipitating the extract solution which was condensed to 1∶10(herb:the herb solution) with the concentration of chitosan clarify agent at 8% at a heating temperature of 50 ℃;ZTC1+1-Ⅱ:precipitating the extract solution which was condensed to 1∶10(herb:the herb solution) with the concentration of chitosan clarify agent at 5% and the heating temperature at 70 ℃,and the adding sequence of ZTC 1+1-Ⅱ natural clarify agents was clarifier B before clarifier A.CONCLUSION:Chitosan and ZTC1+1-Ⅱ natural clarify agents can be used to effectively remove the impunity of extract of Folium Isatidis.
