Problems solved by technology

[0003] Most of the traditional notoginseng powder is only above 100 mesh, and the in vitro dissolution of different degrees of notoginseng is also different, so the traditional notoginseng powder is difficult to dissolve in water, it is difficult for the human body to fully absorb, and its absorption rate is only about 40%

Embodiment 1

[0015] Embodiment 1 uses the method of the present invention to prepare nanoscale superfine notoginseng powder

[0016] Take 10kg of Panax notoginseng, remove impurities; then dry at low temperature; crush the dried Panax notoginseng with a grinder with a mesh size of 300 or more, and then grind it into a fine powder of Panax notoginseng with a ball mill; add the fine powder of Panax notoginseng into a high-speed mixer, and add 10 times the volume Water, stirred at a speed of 1000 rpm to form a suspension; stop stirring after 10 minutes, pass the suspension quickly through a 1000-mesh steel sieve, and collect the sieved Panax notoginseng powder suspension; the unsieved suspension Continue to add water and repeat the stirring; the collected notoginseng powder suspension is dried at a low temperature of 18° C. to obtain nano-scale ultrafine notoginseng powder, weighing 83.7 kg, and the yield is 83.7%.

Embodiment 2

[0017] Embodiment 2 uses the method of the present invention to prepare nanoscale superfine notoginseng powder

[0018] Take 500g of Panax notoginseng medicinal material, pass it through a 20-mesh steel sieve to remove impurities, and dry at 50°C for 6 hours; crush the dried Panax notoginseng with a grinder with a mesh size above 300, and then grind it into a fine powder of Panax notoginseng with a ball mill; fine powder of Panax notoginseng Add a high-speed mixer, add 10 times the volume of water, and stir at a speed of 1000 rpm to form a suspension; stop stirring after 15 minutes, pass the suspension quickly through a 2000-mesh steel sieve, and collect the sieved notoginseng powder suspension Continue to add water to the unsifted suspension, and repeat the stirring; the collected notoginseng powder suspension is dried at a low temperature of 18°C ​​to obtain nano-scale ultrafine notoginseng powder, weighing 374kg, and the yield is 74.8%.

Abstract

The invention relates to a method preparing nano-level notoginseng root powder, and belongs to the field of processing materials. The method comprises the followings steps of: performing crushing, impurity removal, air drying and grinding of notoginseng root by ultramicro crushing technology to obtain notoginseng root powder, adding water into the notoginseng root powder while stirring at a high speed to obtain suspension, screening the suspension by a 1,000-mesh steel screen, and collecting and performing low-temperature drying to obtain the finished product. The method for preparing the nano-level notoginseng root powder has the advantages that: the operating method is simple, the broken wall rate of notoginseng root cells is over 90 percent, the effective ingredients are easily dissolved into water, and bioavailability and absorptivity are high.

Description

technical field [0001] The invention relates to a preparation method of nano-scale notoginseng powder, which belongs to the field of material processing. Background technique [0002] Panax notoginseng is a plant of Araliaceae, which is a unique and precious Chinese medicinal material in my country. Traditional Chinese medicine believes that it is sweet, slightly bitter, and warm in nature. It belongs to the liver and stomach meridian. It has the effects of promoting blood circulation, removing blood stasis, reducing swelling and stopping bleeding. Modern medical research shows that the main active ingredients in Panax notoginseng are ginsenosides Rb1, Rd, Re, Rg1, Rg2, Rh, Panax notoginseng saponins R1, R2, R3, R4, and also contain a variety of volatile oil components and flavonoids , polysaccharides and Panax notoginseng, etc. The saponins in Panax notoginseng have the most significant medicinal activity. They have the functions of strengthening the heart, constricting b...
