Mahuang Fuzi Xixin Decoction Attenuates Th1 and Th2 Responses in the Treatment of Ovalbumin-Induced Allergic Inflammation in a Rat Model of Allergic Rhinitis

Figure 2

Total ion chromatograms of MFXD. 10 groups of MFXD consisting of different batches of Mahuang, Fuzi, and Xixin were diluted to 0.06 g/mL and precipitated with equal methanol. The supernatants were obtained by centrifugation (10000 rpm) for 10 min and analyzed by UPLC-MS/MS using a mobile phase consisting of acetonitrile (a) and 0.1% formic acid aqueous solution (b) with a gradient program. The injection volume was 1 μL, the flow rate is 0.4 mL/min, and the column temperature was 25°C. (a) The total ion chromatograms of 10 groups of MFXD. (b) The MFXD fingerprint.
