Abstract

The invention relates to the preparation method of gynura japonica alkaloid, which comprises the following steps of: 1) crushing gynura japonica medicine materials, adding aqueous ammonia to soak the gynura japonica medicine materials, and adopting 80-95% of ethanol solution as a solution medium to extract the gynura japonica medicine materials through ultrasonic wave to obtain extract; 2) concentrating the extract to obtain extractum, dissolving the extractum through acid water, filtering the solution, adding an alkali liquid into the filtrate until precipitate cannot be produced any more, and filtering the precipitate; and 3) purifying the obtained precipitate through a macroporous resin column to obtain the gynura japonica alkaloid. The process in the invention is simple and easy to operate, lead to less pollution on the environment, and is suitable for industrialized production.

Description

Technical field: [0001] The invention relates to a preparation method of chrysanthemum notoginseng alkaloids, in particular to a method for adsorbing and purifying chrysanthemum notoginseng alkaloids with macroporous resins. Background technique: [0002] Chrysanthemum notoginseng dicotyledonous plant medicine Compositae plant notoginseng root, also known as soil notoginseng, gold not changing, purple notoginseng, chrysanthemum leaf notoginseng, etc., has the effect of dispelling blood stasis, relieving pain, nourishing qi and absorbing blood, and is used for the treatment of falling Injuries, fractures, traumatic bleeding, vomiting blood, postpartum abdominal pain and other diseases. Chrysanthemum notoginseng is mainly distributed in Sichuan, Yunnan, Guangdong, Guangxi, Jiangsu, Jiangxi, Hunan, Guizhou and other places. [0003] Chrysanthemum notoginseng mainly contains alkaloids and flavonoids, and its main active ingredient is alkaloids. Existing extraction methods of c...
