| Abstract: | OBJECTIVE To compare the information content of each fingerprint of Rhizoma Chuang riong and to discuss the feasibility of information-theoretic method. METHODS Rhizoma Chuanxiong was extracted by three methods with different solvents. The extract was detected by HPLC-DAD. The chromatographic fingerprint was quantified by the information content. RESULTS The optimum extraction condition was confirmed: extracting by 60%etrmnol under ultrasonic. CONCLUSIONS The information-theoretic method to evaluate the performance of extraction conditions of Rhizoma Chuanxiong is feasible. |
