The discovery and verification of components are prerequisites for developing of component preparations. The molecular docking technique and pharmacodynamic activity evaluation provide effective methods for the discovery and verification of the representative components of Chishao terpene glucoside components (CSTGCS) against ischemia and hypoxia injury. The chemical constituents of CSTGCS were analyzed qualitatively by UPLC-TOF/MS/MS. Main chemical constituents were docked with key receptor proteins of myocardial ischemia to preliminarily screen anti-ischemia active ingredients, and screening for main active ingredients with Libdockscore. Then a H9c2 cell hypoxia injury model was established, and creatine kinase (CK), lactate dehydrogenase (LDH), superoxide dismutase (SOD), malondialdehyde (MDA) were determined to screen the representative combinations in CSTGCS. In addition, apoptosis index, apoptotic protein expression and mitochondria-associated mRNA levels were determined to verify the inhibition of the representative components (RCS) on the apoptosis of hypoxic cells. Eventually, the representative components of CSTGCS were determined. The results showed that paeoniflorin, albiflorin, benzoyl paeoniflorin and oxypaeoniflorin were considered to be the main active components because of their high matching with target proteins (4TWT, 3O4O, 4KZN, 1M9J) in space and energy. There was no statistical difference in regulating CK, LDH, SOD, MDA levels and maintaining mitochondrial function as well as inhibiting cell apoptosis between CSTGCS group and RCS group (paeoniflorin + albiflorin + benzoyl paeoniflorin combination). Therefore, paeoniflorin, albiflorin and benzoyl paeoniflorin were selected as the most representative ingredients of CSTGCS against ischemia and hypoxia injury, providing a basis for the overall properties of the components and formulation of CSTGCS.
