Determination of Icariin content of TusiyuZhang composition by HPLC
Abstract: Objective To establish the method for the determination of Icariin content of Tusiyu Zhang composition by HPLC. Methods Agilent ZORBAX SB-C18 (250 mm, 4.6 mm, 5 μm) was used as the chromatographic column, and acetonitrile-water (25:75) was used as the mobile phase. The flow velocity was 1.0 mL/min,and the detection wave length was 270 nm. Results The method showed a good linear relationship in the range of 0.1036~2.072 ?g, with R2 as 0.9998. The average recovery rate was 100.6% with a 2.08% RSD. Conclusion The developed method is simple, accurate, reproducible, which can be applied for the quality control of Tusiyu Zhang composition.
