TITLE:
摘要:

目的:建立测定旋覆花药材中旋覆花素和去乙酰旋覆花素含量的方法。方法:采用高效液相色谱法。色谱柱为Zorbax

SB-C18,流动相为乙腈-水(梯度洗脱),流速为1.0 ml/min,柱温为25 ℃,检测波长为210 nm,进样量为10 μl。结果:旋覆花素和去

乙酰旋覆花素的检测质量浓度线性范围分别为0.000 2~0.005、0.000 1~0.001 7 μg/ml(r=0.999 8、0.999 4);精密度、稳定性、重

复性试验的RSD<2%;加样回收率分别为99.63%~103.56%、95.98%~101.21%,RSD分别为1.26%、1.84%(n=9)。结论:该方

法操作简便,结果准确、可靠,可用于评价旋覆花药材的质量。

ABSTRACT:

OBJECTIVE:To establish a method of simultaneous determination of inulicin and deacetylinulicin in Inulae Flos.

METHODS:HPLC was performed on the column of Zorbax SB-C18 with mobile phase of acetonitrile-water(gradient elution)at a

flow rate of 1.0 ml/min,the column temperature was 25 ℃,the detection wavelength was 210 nm,and the injection volume was

10 μl. RESULTS:The linear range was 0.000 2-0.005 μg/ml(r=0.999 8)for inulicin and 0.000 1-0.001 7 μg/ml(r=0.999 4)for

deacetylinulicin;RSDs of precision,stability and reproducibility tests were lower than 2.0%;recoveries were 99.63%-103.56%

(RSD=1.26%,n=9)and 95.98%-101.21%(RSD=1.84%,n=9),respectively. CONCLUSIONS:The method is simple,accurate

and reliable,and can be used for the quality evaluation of Inulae Flos.
