Embodiment 1

[0025] The preparation of the total alkaloids of embodiment 1 Gongluo wood

[0026] Weigh 100g of hardwood powder, add 1200ml of 50% ethanol, reflux extraction at 90°C, filter, recover ethanol to 200ml, then reflux extraction with 2% sulfuric acid, filter, adjust PH8-9, stand still, filter to obtain the filtrate After adding 15% sodium chloride, adjust the pH to 1-2, filter, wash the precipitate with water, and dry at 80°C. Dissolve the precipitate in distilled water, then extract it with 2% sulfuric acid under reflux, adjust the filtrate to pH 8-9, let stand, filter, Obtain filtrate, after adding 15% sodium chloride, regulate PH1-2, filter, precipitation washing, 80 ℃ of dryings, obtain purity and be 52.12% (wherein the content of jatrorrhizine hydrochloride, palmatine hydrochloride, and argonine hydrochloride are respectively 21.89%, 2.72%, 27.51%) of the total alkaloids.

Embodiment 2

[0027] The preparation of the total alkaloids of embodiment 2 Gongluo wood

[0028] Weigh 100g of broad-leaved eucalyptus powder, add 1200ml of 50% ethanol, reflux extraction at 90°C, filter, recover ethanol to 200ml, then extract with 2% sulfuric acid, filter, adjust PH8-9, stand still, filter to obtain the filtrate, Add sodium chloride at 15%, stir to dissolve, add hydrochloric acid, adjust PH1-2, filter, wash the precipitate with water, dry at 80°C to obtain extract, dissolve this extract in distilled water, take equal parts, and put them on D113 and On the HPD100 resin column, distilled water and 10% ethanol remove impurities, and 50% acid alcohol elutes to obtain a purity of 67.94% respectively (wherein the contents of jatrorrhizine hydrochloride, palmatine hydrochloride, and jatrorrhizine hydrochloride are respectively 40.11%, 16.58% %, 11.26%) and 59.55% (wherein the contents of jatrorrhizine hydrochloride, palmatine hydrochloride, and quinine hydrochloride are 31.22%, ...

Embodiment 3

[0029] The preparation of the total alkaloids of embodiment 3 Gongluo wood

[0030] Weigh 150g of broad-leaved eucalyptus powder, add 1800ml of 50% ethanol, reflux extraction at 90°C, filter, recycle ethanol to 300ml, then extract with 2% sulfuric acid solution, filter, adjust pH to 8-9 with ammonia water, stand still, and filter to obtain The filtrate was adjusted to PH1-2, PH3-4, and PH5-6 with hydrochloric acid, respectively, and was respectively placed on the macroporous resin HPD100. First, the impurity was removed with distilled water, and then eluted with 30% ethanol. The recovered eluent had a purity of 44.79% respectively. % (wherein the contents of jatrorrhizine hydrochloride, palmatine hydrochloride, and quinine hydrochloride are respectively 22.14%, 11.91%, and 10.74%), 43.25% (wherein the contents of jatrorrhizine hydrochloride, palmatine hydrochloride, and quinine hydrochloride The total alkaloid content is 21.54%, 11.94%, 10.22%), 43.90% (wherein the contents of...

Abstract

The invention relates to a method for extracting and purifying total alkaloid of Chinese mahonia stem; wherein the total alkaloid can be used to prevent and treat gastric ulcer, is mainly composed of berberine hydrochloride, jatrorrhizine hydrochloride, palmatine hydrochloride, and other alkaloids, and can be solely used or cooperatively used with pharmaceutically-acceptable carriers to prepare drugs for preventing and treating gastric ulcer.

Description

Technical field: [0001] The invention relates to the preparation of total alkaloids of gonglao wood and the application of the total alkaloids and its pharmaceutical composition in medicines for preventing and treating gastric ulcer. Background technique: [0002] Gastric ulcer is a common clinical disease and one of frequently-occurring diseases. It is a digestive system disease with many complications, slow healing and easy recurrence. The incidence rate is increasing year by year. In terms of epidemiology, peptic ulcer is a common disease, and its incidence rate varies greatly in different periods and regions, and the total incidence rate accounts for about 10-20% of the population. About 10% of patients with peptic ulcer disease in the United States, 12.3% in Germany; According to a survey in a few areas in my country, the incidence of digestive tract diseases is 11.43%, of which the incidence of peptic ulcer is 4.54%. The pathogenesis of gastric ulcer is complex and ha...
