目的利用高效液相色谱法,建立了金锁固精丸中沙苑子苷含量的测定方法。方法在流动相为乙腈-0.1%磷酸溶液(11:89);检测波长为266nm;流速为1.0ml/min。结果进样量为10μl的色谱条件下,沙苑子苷在7.5~150μg/ml范围内呈线性关系(r=0.9967),平均加样回收率为99.2%,RSD为0.3%(n=5)。结论该方法简便快捷,准确、重现性好,可用于金锁固金丸的含量测定。
OBJECTIVE To establish a HPLC method for the determination of compstudin in Jin Su Gu Gu Jing Wan. The method was acetonitrile-0.1% phosphoric acid solution (11:89) in mobile phase; the detection wavelength was 266nm; the flow rate was 1.0ml / min. Results Under the chromatographic conditions of 10μl, the linear range was 7.5 ~ 150μg / ml (r = 0.9967). The average recovery was 99.2% and the RSD was 0.3% (n = 5). Conclusion The method is simple, rapid, accurate and reproducible. It can be used to determine the content of Jin Su Gu Jin Jin Wan.
