目的 考察不同用量的吴茱萸炮制黄连对小檗碱的影响以及萸黄连中吸收吴茱萸成分的情况。方法 以小檗碱、吴茱萸碱、吴茱萸次碱为指标，采用高效液相色谱法测定黄连，吴茱萸，10 %，2 0 %，30 %，40 %，5 0 %萸黄连中的成分含量。结果 黄连用吴茱萸炮制后小檗碱的含量减少，2 0 %，30 %萸黄连中小檗碱的含量较高；萸黄连中确实吸收了吴茱萸中的成分。结论 吴茱萸炮制黄连的用量以 2 0 %为宜。

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.
