Effect of Tangweian Jianji on upper gastrointestinal remodeling in streptozotocin-induced diabetic rats

Figure 1 High pressure liquid chromatograph/mass spectrometry analysis of Tangweian Jianji extract. A: Representative total ion current (TIC) chromatograms of the Tangweian Jianji (TWAJJ) extract were obtained in positive ion electrospray; B: TIC chromatograms of the TWAJJ extract was obtained in negative ion electrospray. Visual inspection of the two TIC plots shows that the two modes of ionization generate different constituent information based on the ionizability differences of the components in TWAJJ. A total of 32 peaks were observed. The most abundant compounds identified are Naringin (peak 12), Neohesperidin (peak 15), Lobetyolin (peak 16), Atractylenolide (peak 26) and Emodin (peak 23).
