Embodiment 1

[0027] Preparation method of Magnolin

[0028] (1) Preparation of crude extract:

[0029] Grind 250g jujube kernels, pass through a 40-mesh sieve, degrease with petroleum ether, add 1200ml, 800ml, 600ml of 70% ethanol aqueous solution, heat and reflux for extraction 3 times, each time for 1 hour, filter, and combine the extracts , the filtrate is concentrated with ethanol until it has no alcohol smell, then dissolved with 2 times the amount of water, extracted 5 times with n-butanol, the extract is concentrated under reduced pressure, and the solvent is recovered to obtain the n-butanol crude extract, which is the sample to be separated. figure 1 shown.

[0030] (2) Adopt high-speed countercurrent chromatography to separate magnolialine and spinosin, 6 "'-feruloylspinosin:

[0031] Take n-butanol, ethyl acetate and water at a volume ratio of 2:3:5, place them in a separatory funnel to prepare a two-phase solvent system, take the upper phase as the stationary phase, and the l...

Abstract

The invention discloses a use and preparation method of magnoflorine in preparation of a medicament for preventing and treating insomnia and depression. The preparation method utilizes high-speed countercurrent chromatography to separate magnoflorine. Compared with the prior art, the method for separating and purifying an alkaloid monomer magnoflorine has high monomer preparation and purificationefficiency, a large preparation amount, a low loss, high product purity, simple operation, economy and environmental friendliness. The high performance liquid chromatography (HPLC) detection result shows that the alkaloid monomer magnoflorine separated and purified through one step has purity of 95% or more. The animal pharmacodynamic experimental result shows that the magnoflorine can significantly improve and treat insomnia and depression.

Description

technical field [0001] The invention relates to a medicine and health product field, and relates to the application and preparation method of magnolanine, an active ingredient of alkaloids, in the treatment of depression and insomnia. Background technique [0002] Depression is a syndrome characterized by significant and persistent depression as the main clinical manifestation. In severe cases, suicide and self-mutilation will occur. At present, the global incidence of depression has reached 3.3%, while in developed countries it exceeds 6%. There are more than 700 million people with depression worldwide, and the prevalence of depression in my country is between 3% and 5%. With the development of society, this figure is still rising. Insomnia refers to the inability to sleep normally. The specific symptoms are tossing and turning, poor sleep quality, and reduced sleep time. Severe cases may cause insomnia all night [3] . In today's society, more and more people suffer from ...
