Rapid Separation and Determination of 12 Kinds Phenolic Acids and Isoflavone in Iris Pseudoacorus Based on Ultra-performance Convergence Chromatography
Abstract:A method was developed for the rapid separation and determination of 12 kinds phenolic acids and isoflavones in Iris pseudoacorus based on Ultra performance convergene chromatography. The compounds were separated on a Waters Acquity UPC2 HSS(100mm×3. 0mm,1. 7μm) column at 30 °C by using CO2 and acetonitrile as the mobile phase at a flow rate of 0. 4mL/min, and then analyzed by a UV detector at wavelength of 270nm, the whole analysis progress was only 36 min. The results showed that the limits of detection (LOD… Show more
