Abstract:
Object To study the degree of deacetylation of chitosan and its residual amount left over in the clarified products when chitosan was used as a clarificant. Methods The free amino group in the deacetylated chitosan was determined by linear titration. Results The degree of deacetylation of chitosan was found to be about 80%. The residual amounts left over in the clarified products were lower than 10 -4 . Conclusion The results suggested that it is feasible to use chitosan as a clarificant for refining water extract of TCM.
