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 an extract of Cordyceps sinensis and Cordyceps militaris and a preparation method thereof. The Cordyceps sinensis and Cordyceps militaris are respectively ground, sieved, soaked and stirred in water 18-22 times the weight of Cordyceps sinensis and Cordyceps militaris respectively at 38-42°C, The soaking time is 9-11 hours; filter the Cordyceps sinensis and Cordyceps militaris medicinal liquid respectively, and the filtrates are respectively fixed to a concentration of 0.045g / ml-0.055g / ml, and then filtered to obtain the Cordyceps sinensis extract and Cordyceps militaris extract respectively ; The Cordyceps extract and the Cordyceps militaris extract are mixed at a mass ratio of 1:1-5 to obtain the Cordyceps and Cordyceps militaris extracts. The preparation method of the invention is simple and easy to operate, and saves production cost. The obtained various extracts have better whitening and antioxidant effects than those of Cordyceps sinensis or Cordyceps militaris, and will not stimulate the proliferation of skin cells. The obtained various extracts can be processed into various products, which are widely used in medicine, health products, food and beauty products.

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...
