Flavonoid constituents of Euonymus fortunei

Evaluations of Hemostatic Activity of Ethanol Extract of Euonymus fortunei Aerial Parts

“…Meanwhile, the n-butanol fraction exhibits stronger hemostatic activity than the total fraction, indicating that the n-butanol fraction may be the best hemostatic part, and its hemostatic effect may be related to platelet aggregation and clotting factors. According to our previous research, flavonoids such as kaempferol-3,7dirhamnopyranoside and kaempferol-3-(4″-Oacetyl)-O-α-L-rhamnopyranoside-7-O-α-Lrhamnopyranoside, are the main components in the n-butanol fraction of E. fortunei [8,20]. In addition to usually regarded as polyphenolic compounds with antioxidant activity, kaempferol-3,7-dirhamnopyranoside can also have a hypoglycemic effect [21], and may also be used for cardiovascular treat cardiovascular disorders, exerts endothelium-dependent and independent vasorelaxation in thoracic aorta of normotensive and hypertensive rats [22].…”

“…It is reported that E. fortunei can significantly prolong the coagulation time of mice at high doses, reduce the hemorheological indexes of rats with acute blood stasis syndrome, and has obvious anticoagulation, blood circulation and stasis effects [4]. Chemical composition research shows that E. fortunei is rich in terpenoids, alkaloids [5][6][7] and flavonoids [8,9], which may be the basis of its hemostatic active compositions.…”
