摘　　要：本文建立了双波长分光光度法测定乳浊液中烈香杜鹃油的分析方法，烈香杜鹃油含量在0．005-0．8g·L^-1的范围内线性关系良好（R=0．9999，n=9），平均回收率为99．92％，相对标准偏差为1．64％。该测定方法简便快速，结果准确，为性质相似的其它油性药物在乳浊液中含量的分析测定提供了参考。The content of savoury rhododendron oil （SRO） in emulsion is usually determined by the volatile oil determination method, but it is generally tedious and time-consuming. In this study, a dual wavelength spectrophotometric method was established to determine the SRO content in emulsion. The linear range of SRO was 0.005-0.8 g·L^-1（R=0.9999,n=9）. The average recovery was 99.92% with a RSD of 1.64%. The developed method is simple, rapid and accurate. The information obtained in this study would be helpful for the determination of the content of similar hydrophobic drugs in emulsion.
