Correlation analysis between hemostatic activity and commercial grades of Panax notoginseng / 中草药

ABSTRACT

Objective: To explore the correlation between the hemostatic activity and commercial grades of Panax notoginseng. Methods: After treatment with different commercial grades of P. notoginseng, the mice blooding time (BT) and clotting time (CT) were measured. At the same time the prothrombin time (PT), activation part thrombin time (APTT), fibrinogen (FIB), and platelet count (PLT) were also detected by fully automated blood cell analyzer. The contents of dencichine were determined by HPLC. Results: Mice BT, CT, PT, and APTT were decreased and PLT was increased significantly in all the commercial grades of P. notoginseng. Among all the commercial grades, the countless Tou Sanqi Powder has the best hemostatic activity. There is no correlation between the commercial grades and homostatic activity. Different contents of the extracted dencichine were observed among different commercial grades of P. notoginseng. The highest content of dencichine was 0.98% in countless Tou Sanqi and the lowest was 0.52% in 80 Tou Sanqi. There is no statistical correlation between the dencichine and hemostatic activity or dencichine and commercial grades of P. notoginseng. Conclusion: There is no statistical correlation between the commercial grades of P. notoginseng and haemostatic activity or dencichine contents. The dencichine in countless Tou Sanqi which is the cheapest of all displays the better hemostaic activity than those in 13 or 20 Tou Sanqi whose cost is almost as ten times as countless Tou Sanqi's.
