[0003] Panax notoginseng saponins (PNS) is a general term for a series of saponins and their aglycon components extracted from the traditional Chinese medicine Panax notoginseng. figure out
However, the raw materials of Panax notoginseng saponins (PNS) from different manufacturers are currently on the market. Due to the different origins of the medicinal materials Panax notoginseng used for extraction of Panax notoginseng saponins, different parts of the drug, different harvesting time and years, as well as extraction methods and process conditions Different, the chemical composition of the obtained Panax notoginseng saponins (PNS) is not the same, even if it is different batches of Panax notoginseng saponins (PNS) produced by the same manufacturer, its chemical composition and the composition and content of Panax notoginseng saponins are also very different
It is precisely because of the above reasons that the medicinal ingredients and composition of Xuesaitong products on the market are not fixed and unclear, and the medicinal ingredients and composition ratios of products from different manufacturers or different batches vary greatly, which seriously affects the clinical efficacy of the products. and cause a series of adverse reactions and safety problems, therefore, it is urgent for scientific researchers to study and solve
