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...
