Quantitative analysis of curcumin compounds in ginger by ultra-highperformance liquid chromatography coupled with tandem mass spectrometry
Curcumin compounds are important bioactive compounds in ginger, yet their analysis is limited by their low concentrations. In the current research, a highly sensitive and reliable approach for simultaneous quantitative detection of three curcumin compounds in ginger samples was established using ultra-high-performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS). The extraction solvent, volume of extraction solvent, sonication time, and oscillation time were optimized by a single factor experiment. The method validation results showed that the regression coefficients were higher than 0.9990, and the linearity was satisfactory. Matrix effects were negligible with the values of 94.6%-98.8%. The recovery at three spiking levels was between 81.7% and 100.0%, and the precision was less than 5.4%. The approach could be used to determine the curcumin components in ginger samples since the results demonstrate that it is easy to use, practicable, repeatable, and accurate.
