Essential hypertension (EH) is a leading cause of cardiovascular morbidity and mortality. Fructus Tribuli (FT), as a traditional medicine, has been frequently used for thousands of years. The crude Fructus Tribuli (CFT), decoction pieces being processed to remove impurities, have been listed as an important medicine for the treatment of hypertension in the elderly. According to the theory of traditional Chinese medicine, the CFT can enhance the EH treatment after being stir-fried into stir-fried Fructus Tribuli (SFT). At present, whether the SFT can enhance the EH treatment and its potential pharmacodynamic substances and mechanism are unknown. In this study, an integrated ''spectrum-effect relationship-network pharmacology-metabolomics'' strategy was used. Using male spontaneously hypertensive rats as an experimental model, we compared the therapeutic effects of CFT and SFT on EH. Subsequently, to define the pharmacodynamic material basis of SFT in enhancing the EH treatment, the steroidal saponins (main active components of FT) were selected for spectrum-effect relationship analysis. Furthermore, we applied the joint pathway analysis of network pharmacology and metabolomics to explore the underlying mechanism of SFT in enhancing the EH treatment. Results showed that SFT was better than CFT in the EH treatment. The steroidal saponins transformed by stir-frying were the potential pharmacodynamic substances that SFT could enhance the EH treatment. And the mechanism of action might be associated with regulating glycerophospholipid metabolism and arachidonic acid metabolism, especially arachidonic acid metabolism. This study provided a scientific basis for the clinical use of SFT as an important medicine for the EH treatment.
