ABSTRACT
A novel, simple and efficient capillary electrophoresis method was developed to simultaneous determination of six furanocoumarins (psoralen, isopsoralen, imperatorin, isoimperatorin, phellopterin, and cnidilin). The separation buffer consisted of 30â¯mM boric acid, 12â¯mM sulfobutylether-ß-cyclodextrin and 1.5â¯mM 2-hydroxypropyl-ß-cyclodextrin (pH 7.8); the voltage was 20â¯kV, the temperature was 25⯰C and the detection wavelength was at 246â¯nm with a diode array detector (DAD). Under the above conditions, the analytes could be separated with high resolution in less than 7â¯min. This method was used to simultaneously determine the content of psoralen, imperatorin, isoimperatorin and phellopterin in Angelica Dahurica Radix. And good linearities were obtained with correlation coefficients from 0.9992 to 0.9999. The limits of detection (LOD, S/Nâ¯=â¯3) and the limits of quantitation (LOQ, S/Nâ¯=â¯10) ranged from 0.6 to 3.0⯵g/mL and from 2.1 to 9.9⯵g/mL, respectively. The recoveries ranged between 98.8% and 101.8%. The results indicated the method can achieve baseline separation and quantitative analysis of furanocoumarins in Chinese herbal medicines and formulations.
