Methodology Study on HPLC Fingerprint of Rupikang Capsules / 中国中医药信息杂志

Objective To study the HPLC fingerprint methodology of Rupikang Capsules. Methods The precision, stability and repeatability of the fingerprint of Rupikang Capsules were researched by HPLC. The HPLC system:Agilent ZORBAX SB-C18 column (4.6 mm×250 mm, 5μm);the mobile phase:water-0.1% phosphoric acid water-acetonitrile, with linear gradient elution;the flow rate:1 mL/min;the detection wavelength:280 nm.Results The precision, stability and repeatability of Rupikang Capsules met the requirements of HPLC fingerprint technology. Conclusion This method is simple, feasible and can be used as the whole quality control method of Rupikang capsules.
