preparation example 1
[0083] This preparation example provides a kind of ginger flower root extract, and described ginger flower root extract is prepared by following preparation method:
[0084] (1) Freezing the ginger flower root at -15°C for 18 hours, then crushing at -2°C at a low temperature and sieving to obtain 150-mesh ginger flower root powder;
[0085] (2) Mix the ginger flower root powder obtained in step (1) with n-butanol, extract at 25°C for 2 hours, concentrate the solution obtained from the extraction to obtain a concentrated solution; then mix the concentrated solution with ethanol, and extract at 40°C Filter after 1h to obtain the crude extract of ginger flower root;
[0086] Wherein, the mass ratio of ginger root powder, n-butanol and ethanol is 1:10:8;
[0087] (3) The ginger flower root crude extract obtained in step (2) is passed through the macroporous adsorption resin AB-8, and the water liquid is discarded after first washing with deionized water, and then washed with 60wt...
preparation example 2
[0089] This preparation example provides a root extract of Scutellaria baicalensis, which is prepared by the following preparation method:
[0090] (a) sieve after pulverizing the root of Scutellaria baicalensis, obtain 200 mesh root of Scutellaria baicalensis powder;
[0091](b) Mix the root powder obtained in step (a) with the ethanol aqueous solution with a concentration of 60wt% in a ratio of 1:10 in mass ratio, and then concentrate after 8 min of microwave extraction at a power of 600W to obtain the crude extract of root root thing;
[0092] (c) Dissolving the crude extract of Scutellaria baicalensis obtained in step (b) with an aqueous ethanol solution with a concentration of 10 wt%, then purifying with a macroporous resin gel column D101, and eluting with an aqueous ethanol solution with a concentration of 60 wt%, concentrating , to obtain the root extract of Scutellaria baicalensis.
preparation example 3
[0094] This preparation example provides a kind of cocoa seed extract, and described cocoa seed extract is prepared by following preparation method:
[0095] (A) After crushing cocoa seeds to a particle size of 100 mesh, mix the crushed cocoa seeds with n-hexane at a mass ratio of 1:10, soak at 30°C for 3 hours, filter and dry to obtain defatted cocoa seed powder ;
[0096] (B) Mix the defatted cocoa seed powder obtained in step (A) with water and heat it to 45°C, then mix it with biological enzyme and acid, the mass ratio of the defatted cocoa seed powder, water and cellulase is 1:15 : 0.006, under the condition of 45 DEG C and pH 5, carry out the enzymolysis reaction for 1.5h and then inactivate to obtain the cocoa seed enzymatic hydrolysis product;
[0097] (C) Mix the cocoa seed enzymatic hydrolyzate obtained in step (B) with a 60wt% ethanol aqueous solution with a mass ratio of 1:10, perform ultrasonic extraction with a power of 300W for 50min, filter and concentrate to ...
