| Abstract: | 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. |
