ABSTRACT
Objective To establish a HPLC method for the determination of strychnine content in Cidan Capsules. Methods Using Hypersil- C18 as the column and 1 % Acetic acid-acetonitrile (88 ∶ 12) as the mobile phase, HPLC was performed. The detection wavelength was 254 nm. Results The linear range was 0.112~ 0.560 ? g(r=0.999 9). The average recovery rate was 97.36 % , RSD was 1.00 % ( n=5) . Conclusion This method is accurate and specific.
