Identification of Chemical Components of Qi-Fu-Yin and Its Prototype Components and Metabolites in Rat Plasma and Cerebrospinal Fluid via UPLC-Q-TOF-MS

Figure 7

EICs of prototypical components and metabolites of Qi-Fu-Yin in the dosed and control cerebrospinal fluid in the negative and positive ion modes. (A)-(B) Dosed cerebrospinal fluid in the negative mode. (a)-(b) Control cerebrospinal fluid in the negative mode. (C) Dosed cerebrospinal fluid in the positive mode. (c) Control cerebrospinal fluid in the positive mode. Because of the presence of many metabolites in the rat cerebrospinal fluid, they cannot be displayed in the same figure and are, therefore, divided into two panels: (A) and (B).
