Abstract
Objective: To establish an HPLC method for the content determination of strychnine in Jiegu Cuoshang capsule. Method: HPLC was performed on DIKMA C18 column(4.6 mm×250 mm
5 μm)
the mobile phase consisted of methanol-water-glacial acetic acid-triethylamine (76∶230∶2.4∶0.3)and detecting at 254 nm.The flow rate was 1.20 mL·min-1
and the temperature was 30 ℃. Result: The linear range of strychnine was 0.06-1.20 μg(r=0.999 8). The average recovery was 98.2%
and RSD was 2.2%. Conclusion: The method is simple
feasible
and reproducible
and it can be used for the quality control of Jiegu Cuoshang Capsule.
