摘要

目的: 建立HPLC测定清热卡森颗粒中秦皮乙素含量的方法。方法: 反相高效液相色谱法。色谱柱为Kromasil C18(4.6 mm×250 mm

5 μm)

以乙腈-0.1%磷酸(10 ∶90)流动相

流速为1.0 mL ·min-1

柱温为40 ℃

检测波长为346 nm

进样量10 μL。结果: 秦皮乙素的线性范围为0.010 1~0.253 2 μg (r=0.999 9)。平均加样回收率99.1%

RSD 1.14%。结论: 方法操作简单

灵敏

准确

重复性好

可用于清热卡森颗粒的质量控制。

Abstract

Objective: To establish a RP-HPLC method to determine the content of aesculetin in Qingre Kasen Keli. Method: The RP-HPLC method was used.The analytical column was KromasilMC18 (4.6 mm×250 mm

5 μm)

The mobile phase was acetonitrile-0.1% phosphoric acid (10 ∶90).The flow rate was 1.0 mL ·min-1.The detector wavelength was at 346 nm;injection volume was 10 μL. Result: The linear range was within 0.010 1-0.253 2 μg (r=0.999 9).The average recovery was 99.1% (RSD 1.14%). Conclusion: The method is simple

accurate and sensitive

and can be used for quality control of Qingre Kasen Keli.
