Abstract

The invention relates to a preparation method of karanjin. The preparation method comprises the following steps: crushing dried Fordia cauliflora herbs, adding an appropriate amount of distilled water and a bioenzyme for natural hydrolysis to obtain enzymolysis raw materials, carrying out continuous countercurrent extraction on the enzymolysis raw materials with an 85% ethanol solution used as the solvent, concentrating the extract until no alcohol odor exists, adding the concentrated extract to macroporous resin for adsorption, concentrating the eluate, and drying to obtain a crude karanjin product, and separating by a preparative high-performance liquid chromatograph to obtain karanjin. The preparation method provided by the invention has the advantages of stable process, short period, high product yield, good product quality and high product purity (more than 98%).

Description

Technical field: [0001] The invention relates to a method for extracting and preparing active ingredients from plants, in particular to a method for preparing aquacetin. Background technique: [0002] Water xanthin, also known as water xanthin. Needle crystal, soluble in methanol, ethanol, chloroform, benzene, ether, almost insoluble in petroleum ether, dilute inorganic acid. Phantanthin has anti-mycobacterium tuberculosis effect and can be used for the treatment of vitiligo. [0003] Shuiluosan is the dried root of leguminous plant dried bean curd, which has the functions of dispelling blood stasis, reducing swelling, relieving pain, calming the mind, and improving intelligence. Postpartum and postpartum weakness embolism. This product is very rich in resources, mainly produced in Guangxi and Guangdong. It mainly contains active ingredients such as flavonoids, among which the content of lutein is as high as 0.45%. [0004] The extraction method of lutein is seldom disc...
