“…Compendium of materia medica recorded that Panax notoginseng could stanch bleeding, disperse blood stasis, relieve pain, and treat most blood diseases. Yu Qiu Yao Jie recorded that Panax notoginseng had the effects of heying hemostasis, dredging blood vessels, removing blood stasis, and gathering new blood [ 4 ]. In Chinese Pharmacopeia, Panax notoginseng possesses the function of promoting blood circulation and removing blood stasis, hemostasis, detumescence, and pain relief.…”

Panax notoginseng (Burk.) F.H. Chen is the most traditional hemostatic herb in China. Our previous research found that 20(S)-protopanaxadiol showed the hemostatic effect. And 20(S)-panaxadiol (PD) has a similar structure to 20(S)-protopanaxadiol with a dammarane skeleton. So, this article mainly studies the hemostatic effect of PD. The mouse tail amputation and liver scratch models were used to detect the hemostatic effect of PD. Blood routine and plasma coagulation parameters were measured by using a blood analyzer. The platelet aggregometer analyzed the platelet aggregation rate and adenosine triphosphate (ATP) concentration. Moreover, the intracellular calcium concentration ([Ca2+]i), P-selectin (CD62P), PAC-1 (GP IIb/IIIa receptor marker), and cyclic adenosine monophosphate (cAMP) of platelets were also detected. The results showed that PD obviously shortened the bleeding time of the model mouse, affected the RBC and PLT parameters of rats, reduced APTT and TT, elevated FIB concentration, and promoted human/rat-washed platelet aggregation in vitro. PD promoted the release of ATP and [Ca2+]i and slightly increased the expression of CD62P and PAC-1 of platelets without 1 mM Ca2+. After adding 1 mM Ca2+, PD obviously increased ATP releasing and CD62P and GP IIb/IIIa expression rate and decreased the cAMP level of platelets. These parameter changes of PD-caused platelet were inhibited by vorapaxar. Besides, PD increased the phosphorylation of phosphoinositide 3-kinase/protein kinase B/glycogen synthase kinase 3β (PI3K/Akt/GSK3β) of human platelets. PD is an important hemostatic ingredient in Panax notoginseng, which induced platelet aggregation by affecting the calcium signaling and activating the PI3K/Akt/GSK3β signaling pathway.

“…But, until now, few studies have shown that 20(S)-PD affects the blood system. We have found in previous study that PPD can promote the hemostatic of model bleeding rats and induce platelet aggregation by regulating calcium signaling [19]. Gao et al reported that PPD increased ADP-induced platelet aggregation [10].…”

Background: Panax notoginseng (Burk.) F.H. Chen has long been used to stop bleeding for hundreds of years in China. At present, only dencichine and notoginsenoside Ft1 showed the hemostatic effect. Other ingredients from Panax notoginseng need to be further investigated. This study evaluates the hemostatic effect of 20(S)-panaxadiol (PD) and reveals its mechanism. Methods: We performed an in vivo study to measure PD on the hemostatic effect of mouse tail amputation and liver scratch models, and routine blood. Plasma coagulation parameters were measured using a blood analyzer. Platelet aggregation rate and adenosine triphosphate (ATP) release were analyzed by platelet aggregometer. Subsequently, degranulation marker P-selectin (CD62P), PAC-1 (activated GP IIb/IIIa receptor marker), the concentrations of cytosolic Ca2+ ([Ca2+]i) and cyclic adenosine monophosphate (cAMP) were also assessed. Results: PD shorted bleeding time on the mouse tail amputation and liver scratch models and mainly increased blood platelet count in the rats after subcutaneous injection of 4 h. Meanwhile, PD decreased APTT, increased FIB content, and directly induced platelet aggregation. In the absence of Ca2+, PD promoted the increase of [Ca2+]i and ATP, slightly increased CD62P expression and PAC-1 binding of platelets. After the addition of Ca2+, PD treatment markedly promoted platelet activation by releasing ATP level, increasing CD62P expression and PAC-1 binding, and decreasing cAMP level in platelets. Besides, PD increased phosphorylation of phosphoinositide 3-kinase (PI3K), protein kinase B (PKB or Akt), and glycogen synthase kinase 3β (GSK3β) in human platelets. Excitingly, PD-induced changes included platelet aggregation, a decrease of the cAMP content, and the increases of ATP, CD62P and PAC-1, which were significantly reversed by vorapaxar, which showed a similar function as thrombin. Conclusions: PD is an essential hemostatic ingredient in Panax notoginseng for promoting hematopoiesis and thrombopoiesis. PD induces platelet aggregation by affecting calcium signaling and activating PI3K/Akt/GSK3β signaling pathway, which could contribute to the new insight for the treatment of hemorrhagic disease.
