Embodiment 1

[0021] Example 1 Identification of Radix Pseudostellariae Radix

[0022] Get Radix Pseudostellariae and pulverize through a 40-mesh sieve to obtain Radix Pseudostellariae powder. Get 1g of Pseudostellariae Radix Pseudostellariae powder, add methanol 10ml, sonicate for 15min, filter, and the filtrate is concentrated to 1ml, as test solution I; take 1g of the product of the present invention, operate in the same way, and the resulting solution is used as test solution II. Take another 1g of Pseudostellariae as the test material, and prepare Pseudostellariae reference medicinal solution in the same way. Carry out the experiment according to the thin-layer chromatography experiment method stipulated in the current pharmacopoeia, absorb 5 μl of the above solution, and spot it on the same silica gel G thin-layer plate respectively, and use n-butanol-glacial acetic acid-water volume ratio 4:1:1 as the developer, Place in a developing cylinder pre-saturated with a developing agent fo...

Embodiment 2

[0024] Example 2 Determination of polysaccharide content

[0025] 1) Preparation of reference substance solution Accurately weigh 50mg of glucose reference substance dried at 105°C to constant weight, put it in a 50ml volumetric flask, add water to dissolve and dilute to the mark, and obtain a reference substance solution containing 1mg of glucose per 1ml.

[0026] 2) Determination of the standard curve Precisely draw 20, 40, 60, 80, 100, 120 μl of the reference substance solution, put them in 10ml stoppered test tubes respectively, add water successively to make the final volume 2.0ml, add phenol solution (accurately weigh 3g of phenol in In a small beaker, add water to heat to dissolve, transfer to a 50ml volumetric flask, add water to dilute to the mark, and prepare on the same day.) 1.0ml, shake well, quickly add 5.0ml concentrated sulfuric acid, shake well, stand for 5 minutes, put in a boiling water bath for 15 minutes , take out and cool to room temperature under runnin...

Embodiment 3

[0030] Example 3 Extract

[0031] Weigh 4g of Radix Pseudostellariae Pseudostellaria powder through No. 2 sieve, accurately weigh it, put it in a 250-300ml conical flask, add 100ml of water precisely, seal it tightly, soak in cold, shake it from time to time for the first 6 hours, and then let it stand for 18 hours. Filtrate quickly with a dry filter, accurately measure 20ml of the filtrate, put it in an evaporating dish that has been dried to constant weight, evaporate to dryness on a water bath, dry at 105°C for 3 hours, cool in a desiccator for 30 minutes, and quickly and accurately weigh it . Calculated as a dry product, the content of the water-soluble extract from the root of Radix Pseudostellariae must not be less than 16wt%.

[0032] The samples of 20 whiskers from different origins were measured, and the average extract was 20.13wt% on average, which indicated that the Radix Pseudostellariae Radix Pseudostellariae used in the present invention met the requirements. ...

Abstract

The invention relates to a preparation method of pseudostellariae root hair powder and its product and application. The preparation method comprises baking pseudostellariae root hair at 65-85 DEG C for 2 to 6 hours, crushing the pseudostellariae root hair and screening the pseudostellariae root hair powder through a sieve of 60 to 200 meshes. The content of polysaccharide in the pseudostellariae root hair powder is greater than or equal to 7.0 wt% based on glucose. The content of water-soluble extract of the pseudostellariae root hair is greater than or equal to 16wt%. The pseudostellariae root hair powder has good treatment effects on spleen deficiency and fatigue, loss of appetite and weakness after illness or can improve immunity.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine preparation, and relates to a preparation method of Radix Pseudostellaria Pseudostellariae and its products and applications.
