High performance liquid chromatogram of EZP. (a) The liquid chromatogram of the reference substance was composed of 2 peaks, i.e., specnuezhenide (peak 1) and wedelolactone (peak 2). (b) The 2 peaks were also found in the liquid chromatogram of EZP ethanol extract. (c) The 2 peaks were also found in the liquid chromatogram of EZP water extract, and the results showed that the content of specnuezhenide and wedelolactone in the EZP ethanol extract was higher than those in the EZP water extract.
