OBJECTIVE:To establish a method for quick content determination of clobetasol propionate in temeifu pigmentum.METHODS:UV spectrophotometry was used,and the determination was performed at the wavelength of 240nm.RES-ULTS:The detectable concentration of clobetasol propionate have a good linear relationship with its absorbability in the range of 12～18?g/ml.The inter-day and intra-day average recoveries were 99.87%(RSD=1.21%) and 99.79%(RSD=1.01%),respectively.CONCLUSIONS:The present method is rapid and accurate,which can be widely used in small hospitals not equipped with high performance liquid chromatography.

Objective To establish a method for rapid detection of tramadol in urine by liquid-liquid extraction（LLE）-surface-enhanced Raman spectroscopy （SERS）. Methods Tramadol was extracted from urine with chloroform∶isopropyl alcohol （9∶1） extractant and detected in urine samples by enhanced Raman spectroscopy （wavelength 785 nm）. Results The quantitative curve of tramadol was Y=204.35 X−465.62, r=0.9952, and the linear range was 1-100 μg/ml. The detection limit of tramadol by this method （S/N=3） was 0.53 μg/ml. The sensitivity of SERS was higher than that of conventional methods, and it had reasonable reproducibility. Conclusion This method is simple, efficient and economical, and can be used for qualitative and quantitative analysis of tramadol personalized medicine.
