Object To investigate the berberine in Coptis chinensis Franch. processed with various quantity of Evodia rutaecarpa (Juss.) Benth. and the components absorbed from E. rutaecarpa. Methods Taking berberine, evodiamine and rutaecarpine as targets, HPLC method was used to determine the components of C. chinensis, E. rutaecarpa, C. chinensis processed with 10%, 20%, 30%, 40%, 50% E. rutaecarpa. Results The content of berberine in C. chinensis processed with E. rutaecarpa decreased, and that of C. chinensis processed with 20% and 30% E. rutaecarpa was higher than the rest. C. chinensis processed with E. rutaecarpa absorbed the components of E. rutaecarpa really. Conclusion The suitable quantity of E. rutaecarpa is 20% when processing for C. chinensis.

AIM: To establish HPLC-digitized fingerprint spectrum (HPLC-DFPS) of Rhizoma Pinelliae so that it will be applied in quality control of Rhizoma Pinelliae. METHODS: A gradient separated method was applied. Column: Agilent Zorbax ODS C_ 18 ; Mobile phase: acetonitrile-water; Detection-wavelength: 210 nm; Flow rate: 0.5 mL/min; Column temperature: 25℃. RESULTS: Using above optimum chromatograph condition, the HPLC-DFPS and technic parameters of Rhizoma Pinelliae were established. CONCLUSION: Comparison of a group of characteristic peaks suggests that the HPLC-DFPS technology is feasible in quality control of Rhizoma Pinelliae.
