Abstract: Objective: To establish a method for the quality control of Semen Strychni in Zhanjin pills. Methods: An RP-HPLC method for the quantitative determination of strychnine and brucine in Semen Strychni was built.A XTerra TMC18 column(150mm×3.9mm,5μm)was used with a 10mmol/L amonium bicarbonate solution(adjusted to pH 9.5 by ammonia solution)and acetonitrile(75 :25)as the mobile phase.The detective wavelength was 256nm and the column temperature was 35℃.The basifying testing sample was extracted supersonically by chloroform in cold immersion. Results: The linear ranges were 0.432~2.160μg for strychnine and 0.388~1.940μg for brucine.The average recovery and RSD were 100.03% and 2.06% for strychnine,99.41% and 2.41% for bru- cine,respectively. Conclusion: The method was specific,accurate and precise.It could be used for the quality control for Semen Strychni in Zhanjin pills.
