The fine cordyceps polysaccharide is characterized in that the relative molecular weight of the fine cordyceps polysaccharide is about 29.3765 ten thousand, the monosaccharide consists of galactose, mannose and glucose, wherein the mannose and the glucose are 2.1:1.74:1, and are mostly in beta-glycosidic bond configuration, the structure has strong moisture absorption and retention capacity, and the hyaluronic acid which is similar to the fine cordyceps polysaccharide in structure and has strong moisture retention performance on skin is added, so that the fine cordyceps polysaccharide can achieve very good moisture retention performance, and the addition of the glycerol and the carbomer can improve the texture of the mask emulsion and enhance the affinity effect on the skin of a human body. The allantoin as a soothing agent can neutralize the interaction among various materials, reduce the stimulation to the skin of a human body, the citric acid can adjust the pH value of the mask emulsion, so that various components in the mask emulsion achieve the best effect, and finally, the addition of the preservative of methylparaben can effectively inhibit the proliferation of bacteria and fungi and prolong the effective period of the mask emulsion.
The emulsion prepared by the invention is prepared by dissolving fine cordyceps sinensis polysaccharide with uniform texture obtained by refining in deionized water, slowly stirring and adding into a solution added with glycerol, hyaluronic acid, carbomer, allantoin and methylparaben, and then adjusting the pH value by citric acid. The prepared emulsion is milk white semitransparent colloid, has uniform texture, good sticky feeling, easy coating, fineness, smoothness, moist and refreshing skin feeling, slight faint scent, pH of about 5-6, and good oxidation resistance and moisture retention.
Has the advantages that: compared with the prior art, the invention has the following advantages:
1. the novel fine cordyceps sinensis polysaccharide is adopted in the mask emulsion, the antioxidant activity of the novel fine cordyceps sinensis polysaccharide is very high, the capability of removing DPPH and ABTS free radicals and the total reducing power of the novel fine cordyceps sinensis polysaccharide are obviously superior to those of cordyceps sinensis and cordyceps militaris, and meanwhile, fine cordyceps sinensis mycelia obtained through submerged fermentation are low in cost and low in price, and are more beneficial to market popularization.
2. The fine cordyceps sinensis polysaccharide obtained by separating and purifying through a hot water extraction method and a column chromatography method is high in purification efficiency, and the obtained polysaccharide is free of impurities and uniform in components, so that the problems of unclear active ingredients and high impurity content of cordyceps sinensis masks in the current market are effectively solved.
3. The formula of the cordyceps mask emulsion has two active effects of moisture retention and oxidation resistance, and the reasonability and effectiveness of the dispensing design are ensured by adding corresponding reagents to focus on the texture of the mask and the stimulation effect on the skin.

Preparation of phase A: weighing refined Cordyceps polysaccharide according to the above formula, dissolving in a certain amount of 60 deg.C deionized water, sequentially adding allantoin, glycerol, hyaluronic acid, methyl hydroxybenzoate, and flos Rosae Rugosae essence, and stirring to completely dissolve;
preparation of phase B: heating the rest amount of deionized water to 80 deg.C, sequentially adding carbomer under stirring, stirring for 60min to make it fully swell, making into gel substance, and cooling to 30 deg.C.
Slowly adding the phase A into the stirred phase B, adjusting the pH value to 6 by using citric acid, and uniformly stirring to obtain the cordyceps mask emulsion.
The other steps were the same as in example 1.
Test example 1
1. ABTS free radical scavenging test
2.5ml of ABTS (7 mmol. multidot.L)-1) With 0.5mL of potassium persulfate (15 mmol. L)-1) Mixing, reacting at room temperature in dark for 12h, diluting with distilled water to give absorbance value of 0.70 at 734nm wavelength, transferring 0.2mL of the solution, and adding different concentrations (0.1-2.5 g.L)-1) The sample solution of the Leucocephala leucotricha polysaccharide (the fine Cordyceps polysaccharide extract prepared in example 1) and the sample solution of Cordyceps militaris polysaccharide (common Cordyceps militaris strain is adopted as the difference of the fermentation method in example 1), mixing uniformly, keeping the temperature at 25 deg.C for 15min, measuring the absorbance value at 734nm wavelength, using distilled water as blank group, and measuring each sample for 3 times in parallel.
Polysaccharide pairs ABTS+The calculated formula for the scavenging activity is:
Figure BDA0003093597520000071
in the formula: a. the0Blank control absorbance (distilled water instead of sample), A1Absorbance of the test group, A2Only the absorbance of the sample. By comparing the ABTS free radical clearance, it can be clearly seen that the clearance of the Leucospora leucotricha (anamorph of the fine Cordyceps) is significantly higher than that of the Cordyceps militaris as shown in FIG. 1.
2. Test for moisture retention
The test population selects 100 students of Nanjing university for trial, wherein the age of the volunteer is 19-22 years, and the symptoms are mainly manifested by dry peeling and dark skin on the face, and the 100 volunteers use the emulsion prepared in example 1. The test method comprises the following steps: after cleaning the face every morning and evening, the lotion is applied uniformly on the face until the lotion is absorbed, the application is continued for one month, the application result is observed, and the moisture content of the skin is tested; stipulating: an obvious effect is recorded when the moisture content of the skin is increased by more than or equal to 20 percent; an obvious effect is marked when the moisture content of the skin is increased by more than or equal to 10 percent; the effect is weak when the moisture content of the skin is increased by more than or equal to 5 percent; an increase of < 2% in skin moisture content is recorded as essentially no effect.
Note that: the test volunteers did not use any other brand and type of lotion or mask, etc. during the test; the results show that after one month, the obvious effect reaches 55 percent, the obvious effect reaches 32 percent, the effect is 8 percent weak, and the basically no effect is 5 percent; the obvious effect and the obvious effect reach 87 percent, which shows that the moisturizing effect is good.
Therefore, the emulsion prepared by the specific fine cordyceps polysaccharide extract is milk white semitransparent colloid, has uniform texture, good sticky feeling, easy coating, fineness, smoothness, moist and refreshing skin feeling and slight faint scent, has the pH value of about 5-6, and has good oxidation resistance and moisture retention.
