Embodiment Construction

[0007] The specific implementation of the present invention will be described in detail below in combination with specific situations.

[0008] In the concrete implementation of the present invention, a kind of method and application of extracting fenugreek extract from fenugreek, its method is: 3000g fenugreek is pulverized into the coarse powder of crossing 20-30 mesh sieve, first adds the sherwood oil of 30000ml, Reflux extraction at 30-60°C for 1 hour, degrease, and discard petroleum ether; volatilize the medicinal residues to dry petroleum ether, add 30,000 ml of 80% ethanol to soak for 0.5 hours, reflux extraction for 1 hour, and filter to obtain the first filtrate; 30000ml of 80% ethanol, reflux and extract for 1h, filter to obtain the second filtrate, combine the two filtrates, recover the ethanol under reduced pressure until there is no alcohol smell, add distilled water to disperse to a dispersion solution containing 0.3g / mL crude drug, and disperse AB-8 macroporous ...

Abstract

The invention relates to a method for extracting fenugreek extract from fenugreek and application of the fenugreek extract. The method comprises the following steps: crushing fenugreek, firstly addingpetroleum ether, carrying out reflux extraction, degreasing and removing petroleum ether; volatilizing petroleum ether in medicine residues, adding alcohol into the medicine residues, for soaking themedicine residues, carrying out reflux extraction and filtering to obtain primary filtrate; adding alcohol into the medicine residues again, carrying out reflux extraction and filtering to obtain secondary filtrate, combining the primary filtrate with the secondary filtrate, recycling alcohol, adding distilled water and dispersing to obtain a dispersion solution, putting the dispersion solution on resin, firstly eluting by using distilled water and removing water phase; eluting by using alcohol again and removing eluante; eluting the medicine residues by using alcohol again, collecting alcohol eluante, carrying out pressure-reduced recycling of alcohol till no alcohol taste exists, carrying out freeze-drying and crushing to obtain extract which is the fenugreek extract. The application ofthe fenugreek extract to preparation of medicines for treating perimenopausal syndrome is achieved. The fenugreek extract is abundant in raw materials; the preparation method of the fenugreek extractis scientific and is easy to operate; the extraction of total flavonoid from fenugreek can be effectively solved; medicinal value and commercial value of fenugreek are developed; the fenugreek extract has obvious economic and social benefits.

Description

technical field [0001] The invention relates to traditional Chinese medicine, in particular to a method and application for extracting fenugreek extract from fenugreek. Background technique [0002] Fenugreek is the seed of the leguminous plant Rongruba-. When the fruit is ripe, the whole grass is harvested, the seeds are planted, and dried in the sun. Used raw or lightly fried. Function cures mainly: warming the kidney, dispelling cold, relieving pain. In traditional medicine, it is used for kidney deficiency and coldness, cold pain in the lower abdomen, small intestinal hernia, and cold-damp beriberi. With the development of science and technology, new technologies and methods are emerging in the field of pharmaceutical research, and herbal medicines have the advantages of natural and low toxicity compared with chemical medicines, which gradually become the research hotspots of experts and scholars; more medicinal uses of fenugreek The value is gradually being excavate...
