Abstract
Rehmannia glutinosa Libosch, Achyranthes bidentata Bl. (A. bidentata), Dioscorea opposita Thunb, and Chrysanthemum morifolium Ramat (C. morifolium) are known as the ‘Four Huaiqing Chinese Medicine’ in China, which are used as materials for functional foods. In this paper, the constituents of Four Huaiqing Chinese Medicine were identified by UPLC-Q-TOF-MS/MS, and flavones and aromatic compounds are mainly responsible for these herbs. Moreover, C. morifolium exhibited the most significant effect in cobalt chloride-induced HUVECs injury, which could decrease cell apoptosis and the overproduction of ROS, lactic dehydrogenase (LD) and pyruvic acid, and increase the migration capacity of cells. Meanwhile, A. bidentata exhibited the most significant effect in isoproterenol-induced H9C2 cell injury, which could decrease the levels of ROS overproduction, BNP, NO, LD and pyruvic acid. Western blot revealed that C. morifolium and A. bidentata also could decrease the levels of bax/bcl-2 ratio, cleaved caspase-3, cytochrome c, HIF-1ɑ, GLUT1, HKII and PFKFB3, respectively.
