| Hazard Information | Back Directory | [Description]
Safflower, also known as red and blue flower, thorn safflower, mainly contains compounds such as chalcone pigments, flavonoids, phenolic acids, steroids and polysaccharides. Among the safflower yellows, hydroxyl safflower yellow A and dehydrated safflower yellow B (AHSYB) have the highest content, which are the main active ingredients with physiological activity in safflower.Anhydrosafflor yellow B can improve heart and brain blood oxygen supply, reduce ischemic injury, anticoagulant, anti-myocardial ischemia, inhibit platelet aggregation, anti-oxidation, anti-tumor and anti-inflammation and other pharmacological effects. | [Biological Activity]
Anhydrosafflor yellow B (AHSYB) is a quinolone C-glycoside isolated from Carthamus tinctorius. It inhibits ADP-induced platelet aggregation, has significant antioxidant effects in vitro, and has antitoxic activity against H2O2-induced PC12 cells and primary neuronal cells. | [Synthesis]
A method for extracting and purifying dehydrated safflower yellow B in safflower, 1) using warm soaking method to obtain safflower water extract; 2) pretreatment of macroporous adsorption resin; 3) macroporous resin adsorption; 4) macroporous resin Pore resin elution. |
