RESUMO
This paper summarized the chemical structures and amounts of caffeoylquinic acids in Erigeron breviscapus, as well as its prevention and cure effects on ischemic stroke in clinical and possible pharmacological mechanism. The results showed 22 caffeoylquinic acids reported from E. breviscapus, accounting for 29% of all compounds from this herb; The average content of total polyphenols was 36.93%, and more than 95% of components in Erigeron Breviscapus Injection are caffeoylquinic acids, higher than that of scutellarin. Several high quality clinical studies confirmed that Erigeron Breviscapus Injection enhanced treatment performance and improve the neurological score in the treatment after ischemic stroke and had good safety. In pharmacological research, caffeoylquinic acid compounds display anti-oxidant, anti-free radical, anticoagulation, and anti-fibrosis effects, which can protect neuro, vascular endothelial cells, glial cells, and astrocytes. They are also able to inhibit inflammatory, suppress cytokines IL-1, TNF-α, and enhance SOD & GSH-Px, which play a role in different treatment stages of ischemic stroke. So, caffeoylquinic acid is a kind of important chemical in E. breviscapus.
RESUMO
Objective To study the anticoagulation effects of Supplemented Salvia Beverage (SSB) on myocardial ischemia in rats. Methods Rat myocardial ischemia model was induced by occluding the left anterior descending coronary artery,the effects of SSB (8.24,4.12,2.06 g/kg) on the activated partial thromboplastin time (APTT),prothrombin time (PT),thrombin Time (TT),platelet adherence rate,platelet aggregation,length of thrombus and the dry and wet weight of thrombus,as well as amount of Fibrinogen (Fg) were observed. Results Compared with model group,the shortening of PT and TT,and the decrease of Fg were obviously suppressed in high dosage SSB group (P
