Descriptions:
Jujuboside B is one of the saponins isolated from the seeds of Zizyphus jujuba var, has
antitumor activity and the underlying mechanism via induction of apoptosis and autophagy.[1]
Jujuboside B has potent inhibitory effects on collagen-, thrombin-, AA-, and ADP-induced aggregation, also exhibits superior protection on thromboembolic model, it has a significant inhibitory effect on collagen-induced thromboxane A2 production in rat platelets; suggest that it be considered as components of preventive and therapeutic herbal drugs targeting cardiovascular diseases associated with platelet hyperaggregation.[2]
Jujuboside B reduces vascular tension endothelium-dependently by increasing Ca2+Influx and activating endothelial nitric oxide synthase, it is a natural compound with new pharmacological effects on improving endothelial dysfunction and treating vascular diseases.[3]
