Extraction process of clerodendranthus spicatus

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...
