摘　　要：目的:建立高效液相色谱法测定复方吴茱萸碱纳米乳制剂中吴茱萸碱的含量。方法:通过有机溶剂法破乳,采用高效液相色谱法在225 nm波长处测定峰面积,测定复方吴茱萸碱纳米乳中吴茱萸碱的含量。结果:吴茱萸碱在1.25～10μg.mL-1范围内与峰面积呈良好的线性关系;回归方程为A=122 583C-33 922(r=0.999 7);平均回收率为99.96%,RSD为0.31%(n=9);日内及日间精密度的RSD均小于1%(n=5)。结论:建立的高效液相色谱法准确度高、专属性好,可用于吴茱萸碱复方纳米乳中吴茱萸碱的含量测定。OBJECTIVE To establish a method for content determination of evodiamine in the nanoemulsion by HPLC. METHODS Ethanol was used for the emulsion breaking and HPLC was used for the content determination of the nanoemul- sion at wavelength 225 nm.RESULTS Evodiamine showed a good linear relationship with the area in the range of 1.25 - 10μg·mL^-1. The regression equation was A = 322 583C - 33 922 （r = 0. 999 7）; the average recovery was 99. 96% and RSD was 0. 31 % （n = 9） ; RSD of the intra- and inter-day precision were lower than 1 %（n = 5）. CONCLUSION The method is suitable for the determination of the content of evodiamine nanoemulsion.
