【摘要】 目的测定骨疏灵提取物中淫羊藿苷的含量。方法采用高效液相色谱法,色谱柱为Luna C18(250mm×4.6mm,5μm),流动相为乙腈-水(30∶70),检测波长270nm。结果淫羊藿苷的线性范围为0.416～2.496μg,回归方程为Y=2.0×106X-53810(r=0.9999)。结论所用高效液相色谱法简便、快速、准确,可用于测定骨疏灵微球提取物中淫羊藿苷的含量。更多还原

【Abstract】 Objective To determine the content icariin in the extract of Gushuling. Methods HPLC method was performed on Luna C18 column (250 mm×4.6 mm, 5 μm). The mobile phase consisted of acetonitrile- water (30∶70) and the UV detective wavelength was set at 270 nm. Results The curve of icariin was linear within 0.416～2.496 μg, Y=2.0×106X-53 810 (r =0.999 9). Conclusion HPLC method is simple, rapid and accurate, and it is suitable for ananlysis of icariin content in extract of Gushuling .更多还原
