- Abstract
Hawthorn, a commonly used traditional Chinese medicine, has been suggested to have therapeutic effects on cardiovascular disease. However, effective fractions of hawthorn extract in the treatment of cardiovascular disease, together with possible therapeutic mechanisms, remain unclear. This study aimed to investigate the effects of four different polar fractions of hawthorn extract on blood stasis model rats, and explore the possible metabolic mechanisms by using a liquid chromatography–mass spectrometry metabolomics approach. Evaluation of hemorheology and fibrinogen showed that n‐butanol and ethyl acetate fractions of hawthorn extract had significant therapeutic effects on blood stasis model rats. Furthermore, metabolomics analysis showed that n‐butanol and ethyl acetate fractions of hawthorn extract could reverse imbalanced biomarkers in plasma and urine of blood stasis model rats. Additionally, metabolic pathway analysis revealed that plasma biomarkers were responsible for several important pathways, including d‐glutamine and d‐glutamate metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, alanine, aspartate, and glutamate metabolism, sphingolipid metabolism, and arginine biosynthesis. Meanwhile, urine biomarkers were responsible for some important pathways, including phenylalanine metabolism, tyrosine metabolism, and lysine degradation. This study demonstrated that n‐butanol and ethyl acetate fractions of hawthorn extract had significant therapeutic effects on blood stasis model rats, and the underlying mechanisms involved multiple metabolic pathways.
