Figure 7. Chemical component analysis of the JPYS-containing serum. Preparation of JPYS-Containing Serum. Female SD rats were intragastrically administrated with normal saline (control) or JPYS (11.0 g/kg/d) once daily for seven consecutive days. Then, 17 compounds (Rhein, salvianolic acid A, liquiritin, acteoside, calycosin-7-O-β-D-glucoside, rosmarinic acid, formononetin, calycosin, astragaloside IV, atractylenolide I, dioscin, tanshinone IIA, narirutin, nobiletin, hesperetin, stachydrine, betaine) were further quantified simultaneously by HPLC-QQQ-MS/MS.
