Metabolite Characteristics in Tongue Coating from Damp Phlegm Pattern in Patients with Gastric Precancerous Lesion

Figure 1

Mass spectrum peaks of GPL damp phlegm pattern group, GPL nondamp phlegm pattern group, and healthy control group. (a) GC-TOF-MS, (b) UHPLC-QE-MS positive ion mode, and (c) UHPLC-QE-MS negative ion mode. As the examples of the GC-TOF-MS and UHPLC-QE-MS spectra, there were some different mass spectrum peaks among the GPL damp phlegm pattern patients, GPL nondamp phlegm pattern patients, and healthy control people.
