Objective To establish a HPLC method for the content determination of icariin,notoginsenside R1,ginsenoside Rg1,ginsenoside Re and ginsenoside Rb1 in Qianjin Shen’anning capsule by using core-shell chromatographic column. Methods The chromatographic separation was performed on Kinetex C18 column(0.46 cm×10 cm,2.6 μm)using a mobile phase of acetonitrile(A) and water(B) at a flow rate of 1.0 mL/min. The gradient elution mode was as follows:0~6 min,19 %A;6~13min,19 %~29 %A;13~18 min,29 %~40 %A;18~25 min,40 %~19 %A. The detection wavelength and column temperature were set at 203nm and 30℃. The injection volume was 20 μL. Results The linear range of icariin,notoginsenside R1,ginsenoside Rg1,ginsenoside Re and ginsenoside Rb1 were 3.2~32 μg· mL-1(r=0.99985),3.2~32 μg·mL-1(r=0.99975),11.0~110.0 μg·mL-1(r= 0.99995),6.0~60.0 μg·mL-1(r=0.99995),11.0~110.0 μg·mL-1(r=0.99985),respectively. The average recovery was 98.82 %(RSD=0.46 %),97.08 %(RSD =1.21 %),99.64 %(RSD=0.13 %),98.69 %(RSD=1.38 %) and 98.68 %(RSD=2.44 %),respectively. Conclusion The established method is simple,accurate and repeatable,and can be used for the quality control of Qianjin Shen’anning capsule.
