【摘要】 目的:建立滇姜花Hedychium yunnanense的二萜类成分姜花酮(hedychenone)的含量分析方法。方法:C18柱,流动相乙腈-水(9∶1),柱温25℃,流速1.0 mL.min-1,检测波长235 nm。结果:hedychenone的线性范围5.92~29.6μg.mL-1(r=0.999 9)。平均加样回收率为98.9%。精密度RSD<2%(n=5)。结论:本方法简单、有效、可行,可用于滇姜花的质量评价。更多还原

【Abstract】 Objective: To establish an HPLC method for determination of hedychenone in Hedychium yunnanense.Method: C₁₈ Chromatographic column was used,acetonitrile-water（9∶1） as mobile phase,at flow rate of 1.0 mL·min^-1.The wavelength for detection was 235 nm.Result: The linear range of hedychenone was 5.92-29.6 μg·mL^-1（r=0.999 9）.The average recovery was 99.0%,RSD of precision was less than 2%.Conclusion: The method is simple,effective and feasible,and can be used to evaluate the quality of the herb.更多还原
