Embodiment 1

[0016] 1. Cleaning and drying process: take the kidney tea raw material, remove the sundries, wash with water, and dry in the sun.

[0017] 2. Crushing process: crush the sun-dried kidney tea into 40-80 mesh particles.

[0018] 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, filter, that is Yes; the weight ratio of kidney tea and water is 1:4, and the weight / volume (kg / L) ratio of kidney tea and compound cellulase is 1:0.02.

[0019] 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.

[0020] 4. The post-treatment process is: extract the filtrate with ether three times, combine the ether extracts, and evaporate to dryness at 50°C to obtain a tan extract. The volume ratio of the filtrate to ether is 1:0.5. T...

Embodiment 2

[0022] 1. Cleaning and drying process: take the kidney tea raw material, remove the sundries, wash with water, and dry in the sun.

[0023] 2. Crushing process: crush the sun-dried kidney tea into 100-200 mesh particles.

[0024] 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, filter, that is Yes; the weight ratio of kidney tea and water is 1:10, and the weight / volume (kg / L) ratio of kidney tea and compound cellulase is 1:0.1.

[0025] 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.

[0026] 4. The post-treatment process is: extract the filtrate with ether three times, combine the ether extracts, and evaporate to dryness at 50°C to obtain a tan extract. The volume ratio of the filtrate to ether is 1:0.5. ...

Embodiment 3

[0028] Except that the kidney tea extract that has been cooled to room temperature was ultrasonically extracted for 20 minutes in an ultrasonic wave with a frequency of 25,000 Hz, the rest was the same as in Example 1. The yield of extract is 14.5% based on kidney tea raw material.

Abstract

The invention discloses an extraction process of clerodendranthus spicatus, comprising a cleaning and drying process, a crushing and sieving process, a pre-treatment process and a post-treatment process, wherein the pre-treatment process comprises the steps of: adding water and composite cellulase to clerodendranthus spicatus particles, the particle size of which meets the requirement, reacting for 2-5 hours at 30-40 DEG C, and then increasing the temperature to 50-60 DEG C for 2-5 hours, and later cooling the temperature to room temperature, and finally conducting filtration, wherein the weight ratio of the clerodendranthus spicatus and the water is 1:4-10, and the weight / volume (kg / L) ratio of the clerodendranthus spicatus and the composite cellulase is 1:0.02-0.1. Compared with the prior art, by utilizing the composite cellulase to dissolve the cellulose in the clerodendranthus spicatus stem, the useful water-soluble components which are wrapped in the cellulose can be fully extracted, and the inflammation-diminishing, litholytic and diuretic functions thereof are enhanced.

Description

technical field [0001] The invention belongs to the extraction process of plants, in particular to the water extraction process of kidney tea. 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 dimer of caffeic acid rosemary Acids, caffeoy...
