Electrospray ionization mass spectrometry (ESI-MS) were performed on an Aglient 6520 Q-TOF (Agilent, USA) in positive ionization mode. Melting points were determined in open capillary tubes and the ...

The PCA plots for the control, model, RHA-treated groups, and quality control (QC) samples are shown in Figure 7. PCA of data obtained in the positive (ESI+) and negative (ESI–) ion modes revealed ...

Scanning frequency was 0.2 s per mass spectrum. ESI ion source parameters were as follows: capillary voltage, 2000 V (positive ion mode) or −1500 V (negative ion mode); cone voltage, 30 V; ion source ...
