上标油质量标准研究

Study on quality standard for Siang Pure Oil

目的 :建立上标油 (薄荷脑、薄荷油、樟脑、肉桂油、丁香罗勒油等 )质量控制的方法。方法 :采用TLC法对肉桂油、丁香罗勒油进行定性鉴别 ;采用CGC对樟脑和薄荷脑进行定性鉴别、定量测定。结果 :TLC和GC鉴别方法专属性强。CGC法进行含量测定 ,樟脑在 0 .10 18～ 0 .1832 μg间有良好线性关系 (r =0 .9996 ) ,平均回收率为 10 2 .4 % ,RSD =2 .3% ;薄荷脑在 0 .5 94 7～ 1.3875 μg间有良好线性关系 (r =0 .9997) ,平均回收率为 99.2 % ,RSD =1.4 %。 结论 :本质量标准可有效控制上标油质量。

AIM: To establish the quality standard of Siang Pure Oil (menthol, peppermint oil, camphor, cassia oil, basil oil, etc.). METHODS: TLC was used for the identification of cassia oil and basil oil. Capillary gas chromatography (CGC) was used for the identification and determination of camphor and menthol. RESULTS: The TLC and CGC identification were highly specific. The standard curves of camphor and menthol were linear in the range of 0.1018～0.1832μg, and of 0.5947～1.3875μg, respectively. The average recoveries of camphor and menthol were 102.4%, 99.2% and the RSD were 2.3%, 1.4%, respectively. CONCLUSION: This quality standard is capable of effectively controlling the quality of Siang Pure Oil.
