LC-MS chromatograms to detect paeonol in aqueous extract of GJD. The MS analysis was performed in the multiple reaction monitoring with negative-ion electrospray ionization mode and the transition of m/z 165 → 150, 122 for paeonol. a Blank (methanol; solvent) and paeonol standard (0.2, 2, 20 μg/ml). b Aqueous extracts of PE (50 mg/ml) and GJD (50 mg/ml). Paeonol was not detected in the PE and GJD extracts
