From: Assessing the quality of Smilacis Glabrae Rhizoma (Tufuling) by colormetrics and UPLC-Q-TOF-MS
Standard fingerprint chromatographs and mass spectra of the CHA and CHB samples collected by UPLC/QTOF MS (a) Standard fingerprint chromatographs for CHA showing 95 % confidence intervals. b Standard fingerprint chromatographs for CHB showing 95 % confidence intervals (the 95 % confidence intervals resulted in increased precision of the standard fingerprint chromatographs). c The correlation coefficients of CHA. d The correlation coefficients of CHB (the red and blue lines represent the correlation coefficients of CHA and CHB, respectively). * indicates that the peak was identified based on a comparison with the literature [13–15]
