Embodiment 1

[0023] (1) Weigh 20.0g of dried Cordyceps sinensis and grind it to 40 mesh, mix the powder and water at a mass ratio of 1:20, stir and extract in a water bath at a constant temperature of 20°C for 30 minutes, and then filter;

[0024] (2) After filtering, add the mixed solution of glycerin and water with the same quality as water in step (1), stir and extract at a constant temperature in a water bath at 20°C for 30 minutes, then filter, and combine the filtrates extracted twice, wherein the volume ratio of glycerin to water is is 1:20;

[0025] (3) Vacuum concentrate the filtrate obtained in (2) to 10 times the mass of Cordyceps sinensis powder, then centrifuge at 6000r / min for 20 minutes and pass it through a 0.22um filter membrane. The filtrate and glycerin are mixed at a mass ratio of 1:0.5 to obtain the final Cordyceps sinensis extract. The extraction rate of the active ingredient in this embodiment is 83.61%, and the extract is subjected to a stability test. 1,2-butaned...

Embodiment 2

[0029] (1) Weigh 20.0 g of dried Cordyceps sinensis and grind it to 100 mesh, mix the powder and water at a mass ratio of 1:30, stir and extract in a water bath at 100°C for 100 minutes, and then filter;

[0030] (2) After filtering, add the mixed solution of glycerin and water with the same quality as water in step (1), stir and extract at a constant temperature in a water bath at 100°C for 100 minutes, then filter, and combine the filtrates extracted twice, wherein the volume ratio of glycerin to water is is 1:50;

[0031] (3) Vacuum concentrate the filtrate obtained in (2) to 50 times the mass of Cordyceps sinensis powder, then centrifuge at 12000r / min for 20 minutes and pass it through a 0.22um filter membrane. The filtrate and glycerin are mixed in a mass ratio of 1:3 to obtain the final Cordyceps sinensis extract. The extraction rate of the active ingredient in this embodiment is 90.32%, and the extract is subjected to a stability test. Experiments were carried out wit...

Embodiment 3

[0035] (1) Weigh 20.0 g of dried Cordyceps sinensis and grind it to 60 mesh, mix the powder and water at a mass ratio of 1:25, stir and extract in a water bath at 80°C for 80 minutes, and then filter;

[0036] (2) After filtering, add the mixed solution of glycerin and water with the same quality as the water in step (1), stir and extract at a constant temperature in an 80°C water bath for 80 minutes, then filter, and combine the filtrates extracted twice, wherein the volume ratio of glycerin to water is is 1:30;

[0037] (3) Vacuum concentrate the filtrate obtained in (2) to 30 times the mass of Cordyceps sinensis powder, then centrifuge at 8000r / min for 20 minutes and pass it through a 0.22um filter membrane. The filtrate and glycerin are mixed in a mass ratio of 1:1 to obtain the final Cordyceps sinensis extract. The extraction rate of the active ingredient in this embodiment is 92.08%, and the extract is subjected to a stability test. Experiments were carried out with 1,...

Abstract

The invention discloses a method for extracting cosmetics used active matters from cordyceps sinensis, wherein the method is further suitable for extracting active matters from cordyceps sinensis mycelia. The method comprises the following steps: adding pulverized cordyceps sinensis or cordyceps sinensis mycelia and water into an extraction device, heating through water bath, and extracting for the first time; extracting a powder for the second time by using the mixture of glycerol and water; concentrating the obtained extracts in vacuum rotationally, centrifuging and filtering with a microfiltration membrane in sequence; and adding an appropriate amount of a polyol to obtain a final extract. The extract obtained by adopting the method is free from sensitizing organic solvent residue, is improved in the aspects of deterioration and precipitation during storage and is improved in the compatibility with the formula of the cosmetics.

Description

technical field [0001] The invention relates to the field of extraction of traditional Chinese medicines, in particular to an extraction method of active substances of Cordyceps sinensis or active substances of Cordyceps sinensis mycelia used in cosmetics. Background technique [0002] Cordyceps sinensis is a famous and precious Chinese herbal medicine in China, and it is listed as the three major Chinese tonics together with ginseng and velvet antler.
