篇名: HPLC法同时测定不同产地五味子中4种木脂素类成分的含量
TITLE:
摘要: 目的:建立同时测定五味子中4种木脂素类成分的含量,并比较不同产地间的差异。方法:采用高效液相色谱法。色谱柱为Hypersil ODS-C18,流动相为乙腈-水(梯度洗脱),流速为1.0 mL/min,检测波长为217 nm,柱温为30 ℃,进样量为10 μL。结果:五味子醇甲、五味子酯甲、五味子甲素、五味子乙素检测进样量线性范围分别为0.375 3~2.251 8 μg(r=0.999 6)、0.056 8~0.341 1 μg(r=0.999 8)、0.077 4~0.464 4 μg(r=0.999 3)、0.310 5~1.863 0 μg(r=0.999 8);精密度、稳定性、重复性试验的RSD<2.0%;加样回收率分别为97.94%~100.30%(RSD=0.98%,n=6)、97.59%~99.61%(RSD=0.73%,n=6)、100.86%~103.10%(RSD=0.83%,n=6)、98.39%~101.03%(RSD=1.03%,n=6)。结论:该方法操作简便,精密度、稳定性、重复性良好,可用于五味子中4种木脂素类成分含量的同时测定;不同产地五味子中上述4种木脂素类成分含量具有较大差异。
ABSTRACT: OBJECTIVE: To establish a method for the simultaneous determination of 4 lignans in Schisandra chinensis, and compare the differences among different habitats. METHODS: HPLC was performed on the column of Hypersil ODS-C18 with mobile phase of acetonitrile-water (gradient elution) at a flow rate of 1.0 mL/min, the detection wavelength was 217 nm, column temperature was 30 ℃ and injection volume was 10 μL. RESULTS:The linear range was 0.375 3-2.251 8 μg for schizandrol A(r=0.999 6),0.056 8-0.341 1  μg for schisantherin A(r=0.999 8),0.077 4-0.464 4  μg for deoxyschizandrin(r=0.999 3) and 0.310 5- 1.863 0  μg for schisandrin(r=0.999 8); RSDs of precision, stability and reproducibility were lower than 2.0%; recoveries were 97.94%-100.30%(RSD=0.98%,n=6),97.59%-99.61%(RSD=0.73%,n=6),100.86%-103.10%(RSD=0.83%,n=6),98.39%-101.03%(RSD=1.03%,n=6),respectively. CONCLUSIONS: The method is simple with good precision, stability and reproducibility, and can be used for the simultaneous determination of lignans in S. chinensis; there are quite large differences in the contents of 4 lignans in S. chinensis from different habitats.
