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 followschitosanprecipitating the extract solution which was condensed to 1∶10(herbthe herb solution) with the concentration of chitosan clarify agent at 8% at a heating temperature of 50 ℃;ZTC1+1-Ⅱprecipitating the extract solution which was condensed to 1∶10(herbthe 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.
