[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

preparation example Construction

[0181] The preparation method of Xuesaitong pharmaceutical composition of the present invention, comprises the steps:

[0182] Step 1): Weigh notoginsenoside R1, place it in an ethanol solvent, stir and dissolve to obtain solution A;

[0183] Step 2): Weigh ginsenoside Rb2, ginsenoside Rb1, ginsenoside Rg1 and ginsenoside Rc, stir and dissolve in distilled water, heat to 50-70°C, add solution A while stirring, add activated carbon for needles, heat up and boil for 30 -50 minutes, let stand to cool to room temperature, filter out activated carbon;

[0184] Step 3): Put the above filtrate in a vacuum freeze dryer, cool down to -40~-30°C, pre-freeze for 3~5 hours, then control the temperature at -25~-20°C, pressure 10~20Pa, sublimation and dry for 3~ 5 hours, and then control the temperature at 30-50°C, pressure at 1-10Pa, and analyze and dry for 4-6 hours to obtain it.

[0185] In step 1), the mass ratio of notoginseng saponin R1 to ethanol solvent is 0.05-5:100, and the volum...
