Problems solved by technology

[0003] There is a lot of research work on this medicine, which is generally carried out by using different medicinal materials from various origins. Because the content of medicinal materials varies with climate and location, it is uncertain, and the original medicinal materials are not easy to preserve and unstable. The research work is not going smoothly. We It is hoped to prepare an extract of Huangteng so that its quality is stable and its properties are relatively stable, which is conducive to preservation and further research and development.

Embodiment 1

[0020] Select yellow vine, wash, dry, crush and pass through 50 mesh. Weigh 5kg of plant powder and place it in a multifunctional extraction tank, add 10 times the concentration of 70% ethanol solution, heat to 80°C, set the pressure to 1.5 atmospheres and extract twice, combine the extracts, filter, and concentrate under reduced pressure. Prepare a concentrated solution of vine vine; centrifuge it at a high speed, spray dry it, and make 1.46 kg of vine vine extract.

Embodiment 2

[0022] Select Huangteng, wash, dry, crush and pass through 100 mesh. Weigh 5kg of plant powder and place it in a multi-functional extraction tank, add 12 times the concentration of 50% ethanol solution, heat to 130°C, extract twice at a set pressure of 1.5 atmospheres, combine the extracts, filter, and decompress Concentrate to make a concentrated solution of Huangteng; centrifuge it at high speed and spray dry to make 1.87kg of Huangteng extract.

Embodiment 3

[0024] Select yellow vine, wash and dry. Weigh 5kg of medicinal materials and place them in a multifunctional extraction tank, add 6 times the concentration of 85% ethanol solution, heat to 80°C, extract twice at a set pressure of 1.5 atmospheres, combine the extracts, filter, and concentrate under reduced pressure , to make a concentrated solution of the yellow vine; it is centrifuged at a high speed and spray-dried to make 1.23 kg of a yellow vine extract.

Abstract

The invention relates to a method for preparing a Chinese herbal medicine. The method is characterized by comprising the following steps of: (1) selecting and grinding raw common fibraurea stem, adding an ethanol solution, putting the raw material and the ethanol solution into a multifunctional extracting tank, heating and pressurizing, extracting one-three times with two hours every time, merging the extracting solutions and filtering the merged extracting solution, thus obtaining the total extracting solution; (2) concentrating the total extracting solution under reduced pressure to prepare a common fibraurea stem concentrated solution; and (3) centrifuging the common fibraurea stem concentrated solution at a high speed and carrying out spray drying, thus preparing the common fibraurea stem extract. The method has the following advantage that: the extraction rates of the active ingredients are obviously improved.

Description

technical field [0001] The present invention relates to a method for extracting Chinese herbal medicines, specifically, a method for preparing an extract of Huangteng Background technique [0002] Yellow vine Fibraurea recisa Pierre. is a plant of the genus Heliconia in the family Fangjiceae. Medicinal vines and roots have the effects of clearing away heat and detoxification, purging fire and laxative, and diuretic. It has obvious curative effect on the treatment of fungal vaginitis. It is a natural anti-fungal drug; it has a good effect on the treatment of pharyngitis, tonsillitis, jaundice, tuberculosis, dysentery, boils, burns, prevention of meningitis, and lowering blood pressure. Along with the development of Huangteng preparation, the market demand of Huangteng is increasing day by day. The developed preparations include Huangtengsu Suppositories, Huangtengsu Injections, Huangtengsu (Echtein) and Huangtengsu Tablets (Edgein Tablets). [0003] There is a lot of resea...
