High-performance liquid chromatography (HPLC) of standard chemicals (a) and ELAE extract (b). Eight major components (1 to 8) were identified: 1: aucubin, 2: geniposidic acid, 3: catechin, 4: rutin, 5: caryophyllin, 6: isoquercitrin, 7: chlorogenic acid, and 8: astragaloside. The ordinate represents the signal response units (mAU), while the abscissa represents the retention time (min).
