不同产地苍术中茅术醇含量测定

目的对不同产地苍术中茅术醇进行含量测定,为苍术的品质评价提供依据。方法 GC法,选用HP-NNOWax Polyethylene Glycol,氢火焰离子化检测器（FID）,以正十五醇为内标物,气化室温度为270℃,柱温为185℃,氢气流量为40mL.min-1,空气流量为380mL.min-1,进样量为1μL。结果茅术醇线性范围：0.1132～0.6792mg.mL-1（r=0.9999）,平均回收率为99.21%,RSD为1.02%。结论本方法简便、准确、重复性好,可用于苍术药材及其饮片的质量控制。

Determination of Hinesol in Rhizoma Atraxtylodis from Different Areas

Objective To carry out determination of hinesol in Rhizoma Atraxtylodis grown in different locations,so as to provide evidence for evaluating this herb.Methods Gas chromatography was used,with HP-NNOWax Polyethylene Glycol capillary column,hydrogen flame ionization detector（FID）;gasification chamber temperature 270℃;column temperature was 185℃;hydrogen flow at 40mL·min-1,air flow at 380mL·min-1,and sampling volume at 1μL.Results The linear range of hinesol was 0.1132~0.6792mg·mL-1（r=0.9999） and average recovery was 99.21%,RSD was 1.02%.Conclusion This method is simple,accurate,reproducible and suitable for the quality control of the medicinal materials and prepared slices of Rhizoma atraxtylodis.
