A simple and sensitive method has been developed for the simultaneous determination of eight phenolic acids in Danshen preparations based on liquid chromatography with chemiluminescence detection. Chemiluminescence parameters including flow rate, buffer pH, the concentration of luminescent and reactive solutions, were optimized. The analytical performance of the optimized luminol-H2O2 detection was...
Rapid resolution liquid chromatography coupled with electrospray ionization time-of-flight mass spectrometry was developed for simultaneous determination of twelve saponins in Radix et Rhizoma Notoginseng (RRN) with macranthoidine A as internal standard. All calibration curves showed good linear regression (r2 > 0.9935) within test range. The limits of detection of the twelve compounds...
