Problems solved by technology

For example, for the extraction method of Cordyceps militaris, most of the literature reports use water ultrasonic or decoction, the former is not suitable for industrial production, because limited by the ultrasonic attenuation factor, if the diameter of the extraction tank is too large, it will form around the tank. Ultrasonic blank area, and the purchase price of large-volume, high-power industrial ultrasonic equipment is relatively high; the extraction temperature of the latter will affect the extraction rate and stability of nucleoside components represented by cordycepin, due to the higher extraction temperature It will also produce a strong mushroom taste, possibly due to the formation of sulfur-containing octacarbons, which limits the feasibility of developing it into cosmetics

Abstract

The invention discloses a Cordyceps militaris extract and a preparation method and application thereof. The preparation method comprises a step of pretreatment and a step of warm extraction. According to the invention, a physical adsorbent is employed for treating the medicinal material--Cordyceps militaris in advance, then Cordyceps militaris is extracted with water at a low temperature, and finally, freeze-drying is carried out; thus, the preparation method is convenient and energy-saving and is beneficial for industrial continuous production, and above all, not only mushroom-flavor of the obtained Cordyceps militaris extract is eliminated, but also the content of nucleosides with cordycepin as a main index is increased; the Cordyceps militaris extract is applicable as a raw material for preparation of a cosmetic.

Description

technical field [0001] The invention belongs to the field of biomedicine, in particular to an extract of Cordyceps militaris and its preparation method and application. Background technique [0002] Cordyceps militaris (Cordyceps militaris), also known as Cordyceps militaris (L.) Link], belongs to Ascomycotina (Ascomycotina), Sclerotinia (pyrenomycetes), Sphaerinles (Sphaerinles), Ergotaceae (claviticpitaceae) Cordyceps ( Coedyceps), which belongs to the same species as Cordyceps sinensis, is an edible fungus rich in cordycepin, high protein, and amino acids. "Chinese Medicine Sea" records that "Chrysalis chrysalis is sweet and flat in nature and taste, and enters the lung and kidney meridians." "Compilation of Chinese Herbal Medicine" records that "the fruiting bodies and pupae of Cordyceps militaris (Cordyceps militaris) can also be used as Cordyceps sinensis." There are two main types of Cordyceps militaris: one is made from chrysalis in artificial breeding, which is dif...
