目的 建立高效液相色谱法测定护肝宁片中白藜芦醇和虎杖苷含量的方法。方法 色谱条件:色谱柱为安捷伦XDB-C18(4。6 ×250 mm,5 µm),流动相∶乙睛∶水(A∶B)梯度洗脱(0~30 min:A 22%~40%,B 88%~60%;30~40 min:A 40%~22%,B 60%~88%);检测波长:306 nm;流速:1。0 mL·min-1;进样量:10 μL。结果 虎杖苷在2。2298~22。2977 μg·mL-1的范围内呈良好的线性关系(r=0。99999),平均回收率=103。1%,RSD=1。7%;白藜芦醇在1。0008~10。008 μg·mL-1的范围内呈良好的线性关系(r=0。9999),平均回收率=99。7%,RSD=1。2%。结论 本测定方法简便可行,重复性好,可用于护肝宁片的质量控制。
Simultaneous Determination of the Content of Polydatin and Resveratrol in HuGanNing Tablets by HPLC
OBJECTIVE To establish a HPLC method for the determination of resveratrol and polydatin in Hu-ganning tablets.METHODS Chromatographic conditions:chromatographic column was Agilent XDB-C18(4.6 × 250 mm,5 µm),mobile phase∶acetonitrile∶water(A∶B)gradient elution(0-30 min:A 22%-40%,B 88%-60%;30-40 min:A 40%-22%,B 60%-88%);detection wavelength:306 nm;flow rate:1.0 mL·min-1 injection vol-ume:10 μL.RESULTS Polydatin in the range of 2.2298-22.2977 μg·mL-1 showed a good linear relationship(r=0.99999),the average recovery was 103.4%,RSD=1.5%;Resveratrol showed a good linear relationship in the range of 1.0008-10.008 μg·mL-1(r=0.9999),the average recovery was 99.7%,RSD=1.8%.CONCLUSION The method is simple,feasible and reproducible,and can be used for the quality control of HuGanNing tablets.
