Abstract

The invention relates to a preparation method and a use of a hairyvein agrimony effective ingredient, and belongs to the traditional Chinese medicine effective ingredient extraction field. The preparation method comprises the following steps: a, taking the hairyvein agrimony and extracting the hairyvein agrimony by using a 75-95wt% ethanol aqueous solution with the weight being 8-12 times the weight of the hairyvein agrimony to obtain an extract; b, adding activated carbon to the extract, decoloring by heating reflux, filtering, and concentrating until no alcoholic smell to obtain a concentrated liquor; c, sieving the concentrated liquor, adding water to the concentrated liquor for diluting, putting the diluted concentrated liquor on macroporous adsorption resin, washing with water at first until the effluent I is colorless, and then washing with a 70-90wt% ethanol aqueous solution until the effluent II is identified with polyphenol to be negative by the ferric trichloride-ferric potassium cyanide to obtain an eluate; d, concentrating the eluate til no alcoholic smell, and then drying to obtain the hairyvein agrimony effective ingredient. The preparation method has the beneficial effect that the antioxidation effect is achieved by virtue of rational extraction, enrichment and separation methods; the preparation method can be applied to preparing the hairyvein agrimony effective ingredient of an oxidation resisting product.

Description

technical field [0001] The invention belongs to the field of extraction of effective components of traditional Chinese medicines, and in particular relates to a preparation method and application of effective components of Agrimony. Background technique [0002] Agrimonia pilosa Ledeb. was first recorded in Ben Cao Tu Jing, and it is the whole herb of the perennial herbaceous plant Agrimonia pilosa Ledeb. It is also known as Tuolicao, Ledeb. Bitter, astringent, neutral in nature, it belongs to the lung, liver, and spleen meridian. It is often used to treat tumors, Meniere's syndrome, trichomonas vaginitis and other diseases. It has pharmacological effects such as anti-tumor, hemostatic, antibacterial, and insecticidal. It contains flavonoids, triterpenoids, phenols, esters, tannins, volatile oils and fatty acid alcohols. [0003] Agrimony is a drug with development potential, and has broad prospects in the development of food, cosmetics, health products and medicines. Amon...
