摘要
根据香油和其他植物油在299．3nm处吸收的不同，采用紫外二阶导数分光光度法测定香油的含量，其测定的线性范围2～25μL·mL^-1，标准偏差0．77％，加标回收率95．3％～99．4％。该方法简便、快捷，其精密度和准确度均较好，可批量进行检测。
According to absorpting spectrum of sesame oil at the wavelength of 299. 3nm, which differ from other vegetable oil, the detecting method of sesame oil content was established by Second-derivative Ultraviolet Spectrometry. The linear range and standard deviation of sesame oil were 2～25μL · mL^-1 and 0.77% respectively. The standard addition rate of recovery was 95.3%～99.4%. This method was applied much accurately and promptly, and can be used for batch determination.
