Problems solved by technology

[0003] In the prior art, the preparation of Poria cocos polysaccharides and Poria cocos triterpenoids mostly uses traditional organic solvents for reflux extraction. These methods have long production cycles, high energy consumption, no pollution, and low product quality.
The present invention adopts the microwave-assisted extraction method to extract the poria cocos polysaccharide and the poria cocos triterpene. Compared with the traditional method, the extraction rate is high, the extraction rate is about 85% higher than the traditional process, the speed is fast, the amount of solvent required is small, and the selectivity is good. It has the advantages of simple operation and the microwave extraction method does not destroy the active ingredients of Poria cocos. This method has not been reported yet.

Embodiment 1

[0020] The method provided by this embodiment using wave-assisted preparation of solid Poria cocos extract is as follows:

[0021] Pulverize Poria cocos, pass through a 60-mesh sieve, mix with ethanol at a solid-to-liquid mass ratio of 1:5, place in a microwave extraction device, extract twice, each time is 8min, the extraction temperature is 30°C, and the microwave duty cycle is 60%, the power is 800W, then filter with a microporous membrane, discard the filter residue, concentrate the filtrate at 50°C, and freeze-dry to obtain the solid Poria cocos extract, wherein the weight content of poria cocos polysaccharide and poria cocos triterpene is 82% .

Embodiment 2

[0023] The method provided by this embodiment using wave-assisted preparation of solid Poria cocos extract is as follows:

[0024] Pulverize Poria cocos, pass through a 200-mesh sieve, mix with ethanol at a solid-to-liquid mass ratio of 1:10, place in a microwave extraction device, extract 5 times, each time is 3min, the extraction temperature is 30°C, and the microwave duty cycle is 80%, the power is 600W, then filter with a microporous membrane, discard the filter residue, concentrate the filtrate at 45°C, and freeze-dry to obtain the solid Poria cocos extract, wherein the weight content of polysaccharides and poria cocos triterpenoids is 89.2%.

Embodiment 3

[0026] The method provided by the present embodiment to assist the preparation of liquid Poria cocos extract by wave is as follows:

[0027] Pulverize Poria cocos, pass through a 60-mesh sieve, and mix with ethanol at a solid-to-liquid mass ratio of 1:10. Place in microwave extraction equipment, extract 3 times, each time is 5min, the extraction temperature is 30°C, the microwave duty cycle is 80%, and the power is 800W. Then filter with a microporous membrane, discard the filter residue, and concentrate the filtrate to obtain a liquid Poria cocos extract, wherein the weight content of Poria cocos polysaccharide and Poria cocos triterpene is 65.8%.

Abstract

The invention discloses a Poria cocos extract. The content of pachymaran and Poria cocos triterpene in the Poria cocos extract is 55-95wt%. A preparation method of Poria cocos extract comprises the following steps: crushing Poria cocos, sieving, and proportionally mixing with ethanol; carrying out microwave extraction in a microwave extraction device; and filtering through a micro-porous filtering film, abandoning filter residues, and mixing the above filtrates to obtain a liquid Poria cocos extract, or concentrating the filtrates and drying to obtain a solid Poria cocos extract. The invention also discloses the preparation method of the Poria cocos extract. The method has the advantages of mild extraction conditions, fast speed, small application amount of a solvent, good selectivity, simple operation and the like. The Poria cocos extract prepared in the invention is from a traditional Chinese medicine, has the advantages of remarkable effects and high safety factor, has bacterium preventing, inflammation eliminating, high moisturizing, oil secretion regulating, immunity enhancing, oxidation resisting, aging resisting and allergy resisting effects, can be used in health foods and beverages, pharmaceuticals and cosmetics, and enlarges the application value of Poria cocos.

Description

technical field [0001] The invention belongs to the field of natural medicinal chemistry, and in particular relates to a poria cocos extract and its preparation method and application. Background technique [0002] Poria cocos is the dried sclerotium of the polyporaceae fungus proria cocos (Schw.) Wolf, which has a history of more than 2,000 years as a medicinal health product. It is a large variety of traditional Chinese medicine for both medicine and food, which is recorded in "Shen Nong's Materia Medica", and "Chinese Pharmacopoeia" in previous editions. The theory of traditional Chinese medicine believes that it has the effects of promoting water and dampness, invigorating the spleen and nourishing the middle, calming the mind and calming the nerves. It can treat dysuria, edema and fullness, phlegm and cough, spleen deficiency, less food, stool and diarrhea, palpitations, insomnia and dizziness; modern pharmacological research It has been shown that Poria cocos extract ...
