Abstract
The determination of benzoylaconine(BA),benzoylmesaconine(BM),benzoylhypaconine(BH) and benzoyldeoxyaconine(BD) in SHEN-FU injection based on homogeneous ionic liquid microextraction coupled with high performance liquid chromatographic separation was described.The experimental parameters including volume of ionic liquid,pH,extraction time and salt concentration were optimizated,when 0.058 g and 0.26 g NH4PF6 were used as extraction solvent,the target compounds can be extracted from 5 mL of injection,the extraction time is 1 min,neutral and the concentration of NaCl is 50 g/L.The detection limits for BM,BA,BH and BD were 45.5,19.8,26.3 and 12.2 μg/L,respectively.The recoveries of the analytes ranged from 86.54% to 110.67% and relative standard deviations were lower than 6.12%.
