[0025] Example 1. Preparation of chrysanthemum extract:

[0026] (1) Add the raw medicine chrysanthemum and 3%acetate solution to the rotary evaporator at a ratio of 1:20, and extract 60min at 70 ° C to obtain volatile oil;

[0027] (2) Step (1) The extraction of the pharmaceutical residue and acetate solution after extraction is 4 hours insulated at 50 ° C, and the medicinal residue and acid liquid are obtained.neutral;

[0028] (3) In the volatile oil obtained from steps (1), add β-cyclic paste to wrap to form a package for use;

[0029] (4) The sour liquid obtained by the step (2) at 80 ° C is decompressed and distilled to obtain an acid extract, freezing and drying to get frozen dried powder, to be used;

[0030] (5) The obtained pharmaceutical residue obtained by the step (2) is extracted in the 70%ethanol aquatic solution. The ultrasonic power is 400W and the time continues 60 minutes; the medicine residue is abandoned after extraction;Alcohol extract, freezing and drying to...

Abstract

The invention provides a preparation method for Chuzhou chrysanthemum extract powder according to the characteristics of effective constituents contained in Chuzhou chrysanthemum, and the preparation method aims at a plurality of effective constituents of the Chuzhou chrysanthemum. A rotary evaporator is adopted to perform double extraction on the Chuzhou chrysanthemum, extracts of volatile oil and acetic acid are obtained, and then decoction dregs are added into ethanol water to perform extraction again with ultrasonic. Beta-cyclodextrin wrapping is performed on the volatile oil to obtain wrappage. Acid extract solution is concentrated, alcohol extract solution is concentrated after alcohol is recovered, two concentrated solutions are merged, and freeze-dried powder is obtained after the two concentrated solutions are frozen and dried. Eventually, the wrappage and the freeze-dried powder are porphyrized and mixed to obtain the Chuzhou chrysanthemum extract powder. According to the preparation method for the Chuzhou chrysanthemum extract powder, the extract method is selected aiming at the characteristics of the plurality of effective constituents of the Chuzhou chrysanthemum, and each effective substance is retained to the maximum extent; extraction time is short, the temperature for the whole process is smaller than or equal to 80 DEG C, damage to efficacy material is avoided, and the preparation method is high in efficiency, time-saving and labor-saving; and the extract powder can be used in place of the Chuzhou chrysanthemum, and can also serve as raw material for production of medicine and health care products.

Description

Technical field [0001] The present invention involves a preparation method of chrysanthemum extract, which is the field of pharmaceutical care products. Background technique [0002] As a traditional Chinese medicine, chrysanthemum has the effects of sparse wind, heat clearing, bright eyes, and detoxification.The 2010 version of "Chinese Pharmacopoeia" is divided into four types: four types of origin and processing methods.The main chemical components of medicinal chrysanthemums include flavonoids, volatile oils, phenolic acids, total sugar, amino acids and flavoring substances, and inorganic elements.The four kinds of chrysanthemums and Qi Ju, Chuju, Ji Ju, Huaiju and other eight mainstream chrysanthemum commodity medicinal materials collected by the Pharmacopoeia are different origin, different varieties, different appearances, different smells, and different medicinal effects. Study research.There are large differences in the types, content and proportion of the chemicals cont...
