Figure 3From: Quasi-MSn identification of flavanone 7-glycoside isomers in Da Chengqi Tang by high performance liquid chromatography-tandem mass spectrometryExtracted ions chromatogram (EIC) of m/z 609.00 (A) and m/z 579.00 (B) combined with the UV spectra. The retention times of isonarngin, naringin, hesperetin and neohesperetin were 5.5, 8.0, 9.3 and 10.3 minutes respectively.Back to article page
