Embodiment 1

[0035] The preparation method of the Cordyceps sinensis and Cordyceps militaris (1:5) extract described in this embodiment, please refer to the technical process figure 1 , including the following steps:

[0036] a) Warm soaking: Grind Cordyceps sinensis and Cordyceps militaris respectively, sieve, soak and stir in water 20 times the weight of Cordyceps sinensis and Cordyceps militaris respectively, the soaking temperature is 40°C, and soaking time is 10 hours;

[0037] b) Filtration: filter the Cordyceps sinensis medicinal liquid and the northern Chinese caterpillar medicinal liquid respectively, the filtrates are respectively fixed to a concentration of the medicinal liquid of 0.05g / ml, and then filtered to obtain the Cordyceps sinensis extract and the northern Cordyceps extract respectively;

[0038] c) Mixing: the Cordyceps sinensis extract and the Cordyceps militaris extract are mixed at a mass ratio of 1:5 to obtain the Cordyceps sinensis and Cordyceps militaris extracts...

Embodiment 2

[0041]The tyrosinase inhibition experiment described in the present embodiment comprises the following steps:

[0042] a) Mix Cordyceps sinensis extract and Cordyceps militaris extract in different proportions to obtain different ratios of Cordyceps sinensis and Cordyceps militaris extracts, respectively 5:1, 3:1, 1:1, 1:3, 1:5, 1:7 and 1:10.

[0043] b) Each extract was used for the test of tyrosinase activity inhibition, and the test results without any inhibitor were added as the experimental control, and the test results of vitamin C and arbutin (whitening effect) were added as the positive control of the experiment.

[0044] At the same time, the Cordyceps sinensis extract and the Cordyceps militaris extract were respectively obtained by the preparation method in Example 1, and were respectively used in the tyrosinase activity inhibition experiment.

[0045] Tyrosinase activity inhibition test is a traditional test method for screening whitening medicines. Since tyrosin...

Embodiment 3

[0050] The antioxidant capacity experiment described in the present embodiment comprises the following steps:

[0051] a) Mix Cordyceps sinensis extract and Cordyceps militaris extract in different proportions to obtain different ratios of Cordyceps sinensis and Cordyceps militaris extracts, respectively 5:1, 3:1, 1:1, 1:3, 1:5, 1:7 and 1:10.

[0052] b) Establish a standard curve based on the anti-copper ion oxidation ability of Trolox (an analogue of vitamin E).

[0053] c) Each extract was used for the kit test of antioxidant capacity, and the test result without adding any extract was used as the negative control of the experiment.

[0054] At the same time, the Cordyceps sinensis extract and the Cordyceps militaris extract were respectively obtained by the preparation method of Example 1, and were respectively used in the antioxidant capacity experiment.

[0055] see Figure 5 . In this figure, a standard curve is established based on the copper ion oxidation resistan...

Abstract

The invention discloses a cordyceps sinensis and cordyceps militaris extracting solution, and a preparation method thereof. The preparation method comprises following steps: cordyceps sinensis and cordyceps militaris are grinded into powder and sieved respectively, and are immersed in water of 38 to 42 DEG C for 9 to 11h of stirring respectively so as to obtain a cordyceps sinensis medicine liquid and a cordyceps militaris medicine liquid, wherein the weight amount of water used for immersing cordyceps sinensis accounts for 18 to 22 times of that of cordyceps sinensis, and the weight amount of water used for immersing cordyceps militaris accounts for 18 to 22 times of that of cordyceps militaris; the obtained cordyceps sinensis medicine liquid and the obtained cordyceps militaris medicine liquid are filtered respectively, and the obtained filtrates are diluted until medicine liquid concentration ranges from 0.045 to 0.055g / ml, and are filtered so as to obtain a cordyceps sinensis extract and a cordyceps militaris extract respectively; and the cordyceps sinensis extract and the cordyceps militaris extract are mixed at a mass ratio of 1:1-5 so as to obtain the cordyceps sinensis and cordyceps militaris extracting solution. The preparation method is simple; operation is convenient; and production cost is reduced. The obtained cordyceps sinensis and cordyceps militaris extracting solution possesses better whitening and antioxidant effects than that of cordyceps sinensis and cordyceps militaris, and at the same time, skin cell proliferation is not stimulated. The cordyceps sinensis and cordyceps militaris extracting solution can be processed into different products, and can be widely applied to medicines, health care products, food, and cosmetics.

Description

technical field [0001] The invention relates to an extract of Cordyceps sinensis and Cordyceps militaris and its preparation method and application, in particular to an extract of Cordyceps sinensis and Cordyceps militaris with whitening and anti-oxidation effects, its preparation method and application. Background technique [0002] Cordyceps sinensis (Cordyceps sinensis), also known as Chinese Cordyceps, is a traditional precious Chinese medicinal material in Chinese history. It is an ascomycete that parasitizes on the larvae of bat moths. Cordyceps sinensis is mainly produced in Qinghai, Tibet, Sichuan, Yunnan, Gansu and Guizhou in China at an altitude of 3,000 to 5,000 meters. According to "Compendium of Materia Medica": "Cordyceps sinensis is sweet in nature, flat in taste, returns to the lungs, kidney meridian, nourishes the lungs and kidneys, stops bleeding, resolves phlegm, and is used for chronic cough and shortness of breath, impotence and spermatorrhea, and sore w...
