Embodiment 1

[0024] 1. Cleaning and drying process: take the kidney tea raw material, remove the sundries, wash with water, and dry in the sun.

[0025] 2. Crushing process: crush the sun-dried kidney tea into 40-80 mesh particles.

[0026] 3. Pretreatment process: Add water and cellulosic mold to the crushed kidney tea granules, react at 30-35°C for 5 hours, then raise the temperature to 50-60°C, react for 2 hours, cool to room temperature, and then Ultrasonic extraction of 25,000 Hz ultrasonic waves for 20 minutes, filtering, and the weight ratio of kidney tea and water is 1:4, and the weight / volume (kg / L) ratio of kidney tea and composite cellulase is 1:0.02 .

[0027] The compound cellulosic mold is a mixture of Trichoderma sp CGMCC 3.3068 and Trichoderma koningii CGMCC 3.2774, and the volume ratio of the expansion medium is 1:0.5.

[0028] 4. The post-treatment process is: extract the filtrate with ether for 3 times, combine the ether extracts, and evaporate to dryness at 50°C to ob...

Embodiment 2

[0032] 1. Cleaning and drying process: take the kidney tea raw material, remove the sundries, wash with water, and dry in the sun.

[0033] 2. Crushing process: crush the sun-dried kidney tea into 100-200 mesh particles.

[0034] 3. Pretreatment process: add water and cellulosic mold to the crushed kidney tea granules, react at 35-40°C for 2 hours, then raise the temperature to 50-60°C, react for 2 hours, cool to room temperature, and then Ultrasonic extraction of 25,000 Hz ultrasonic waves for 20 minutes, filtering, and the weight ratio of kidney tea and water is 1:10, and the weight / volume (kg / L) ratio of kidney tea and composite cellulase is 1:0.1 .

[0035] The compound cellulosic mold is a mixture of Trichoderma sp CGMCC 3.3068 and Trichoderma koningii CGMCC 3.2774, and the volume ratio of the expansion medium is 1:0.8.

[0036] 4. The post-treatment process is as follows: extract the filtrate three times with ether, combine the ether extracts, and evaporate to dryness ...

Embodiment 3

[0042] Except that butyl acetate is increased in ethyl acetate, and the volume ratio of ethyl acetate and butyl acetate is 10:0.5, all the other are the same as in Example 3, and the obtained extract C yield is calculated as 1.9% based on kidney tea raw material.

Abstract

The invention discloses a preparation method and a composition of a clerodendranthus spicatus extract, wherein the preparation method comprises the working procedures of washing and drying, pulverization and sieving, water extraction, alcohol extraction and ethyl acetate extraction. Compared with the prior art, the preparation method is realized by fully extracting water-soluble, alcohol-soluble and ester-soluble active substances in the clerodendranthus spicatus extract by using biological extraction and chemical extraction, thereby improving the antipyretic, litholytic and diuretic functions of the clerodendranthus spicatus extract and the composition thereof.

Description

technical field [0001] The invention belongs to a preparation method and a composition of a plant extract, in particular to a preparation method and a composition of a kidney tea extract. Background technique [0002] Kidney tea is a plant of the genus Clerodendranthus of the Labiatae family, also known as cat's whiskers. There are about 5 species in the world, and there is only one in my country, which is Kidney tea [C.Spi-catus (Thunb).C.Y.Wu], mainly produced in Guangxi and Guangdong , Yunnan, Fujian, Taiwan and other places. Folks believe that the whole plant has diuretic, antibacterial, anti-inflammatory, stone-dissolving, and stone-dispelling effects. It is often used for acute and chronic nephritis, cystitis, urinary tract stones, pharyngitis, and rheumatoid arthritis. At present, 14 flavonoids have been isolated from the aerial part of kidney tea, 12 of which are flavonoid aglycones and 2 of which are flavonoid glycosides; 8 phenolic acids, namely caffeic acid, the d...
