Exploratory study of APTT bioactivity detection assay for Xuesaitong injection / 中国药理学通报

ABSTRACT

Aim To explore the feasibility of APTT bioactivity detection for Xuesaitong injection. Methods The APTT values of rabbit plasma of samples/reference were detected by automatic coagulometer, and the data were analyzed by bioassay statistics. Results The results of repeated test of different rabbit plasma, multiple enterprises and various concentrations of Xuesaitong injection were stable. The APTT values of standard ginsenoside Rb1, ginsenoside Rg1, notoginsenoside R1 and Panax notoginseng saponins were compared with that of Xuesaitong injection, and the APTT values of the former three were not correlated with Xuesaitong injection; while the Panax notoginseng saponins were significantly correlated with Xuesaitong injection. The panax notoginseng saponins were used as the reference material, and the results were consistent with those of the physical and chemical analysis. Conclusions The active ingredients in Xuesaitong injection do not represent the effective ingredients, and its medicinal effect is the result of the combined action of various ingredients. Therefore, it is not suitable to simply look for some monomer as the control. This paper suggests using panax notoginseng saponins as the control substance to explore the biological activity study of injections for promoting blood circulation and removing blood stasis.
