Abstract
A kind of polysaccharide-k extracting new process belongs to the pharmaceutical technology technical field, and this technology is: manyzoned polypore sporophore is added water boil, adding calcium hydroxide in this leachate makes krestin form complex and precipitates and separate out, in complex, add acid then, make the precipitate dissolving, in lysate, add ethanol, the krestin precipitation is separated out, filter,, promptly get Powdered krestin with washing with alcohol, drying, adopt this technological advantage to be: leachate does not need to concentrate, thereby can reduce a large amount of energy consumptions; Can obtain more stable krestin complex as intermediate, be convenient to store.
Description
The invention belongs to the pharmaceutical technology technical field.
The technology of existing extraction krestin is that manyzoned polypore sporophore is added water boil a few hours, leachate is filtered the back concentrate, and adds an amount of ethanol then, and the krestin precipitation is separated out, and the washing with alcohol after drying use in centrifugalize, gets the former powder of krestin.Because the leachate volume is very big, need to consume a large amount of energy in concentration process when adopting this technology, the operating time is also longer; The former powder of krestin can not long term store.
The present invention has provided the new technology that a kind of krestin extracts, and its objective is and has reduced energy resource consumption.Simultaneously owing to can obtain the krestin complex in producing the former powder craft process of krestin, this complex is comparatively stable, is convenient to store, thereby makes the problem that the former powder of krestin can not long term store obtain solution.
The present invention is achieved in that
1. the manyzoned polypore sporophore water is rinsed well, added certain water gaging then, heated and boiled 5 hours, the leaching leachate adds water boil 5 hours again in the sporophore, so repeat 1～2 time.
2. leachate is merged, add hydrogen calcium hydride or calcium oxide, consumption is 3～30% of a manyzoned polypore sporophore, makes krestin form complex and precipitates and separate out.In addition, the mixture of also available calcium chloride of calcium hydroxide and sodium hydroxide replaces, and the calcium chloride consumption is 4.5～45% of a manyzoned polypore sporophore.
3. leaching precipitate adds hydrochloric acid, consumption with in and calcium hydroxide be as the criterion, make the precipitate dissolving.
4. in above-mentioned solution, add 1～3 times of amount ethanol, the krestin precipitation is separated out.
5. leaching krestin precipitation with washing with alcohol, drying, promptly gets Powdered krestin.
Adopt this technological advantage to be:
1. leachate does not need to concentrate, thereby can reduce a large amount of energy consumptions.
2. can obtain more stable krestin complex as intermediate, be convenient to store.
Embodiment 1.
With 400 gram manyzoned polypore sporophores, the washing back adds suitable quantity of water (the sporophore submergence is got final product), heated and boiled 5 hours, and the leaching leachate adds water boil 5 hours again in the sporophore; Twice leachate merged, add calcium hydroxide 15 grams, make krestin form complex and precipitate and separate out; The leaching precipitate adds 62 milliliters of 6 equivalent hydrochloric acid, makes the precipitate dissolving; Add 2 times of volume ethanol in the gained solution, make the krestin precipitation separate out 1 and filter; Reuse washing with alcohol after drying promptly gets krestin.
Embodiment 2.
As described in the embodiment 1., add water boil with 200 gram manyzoned polypore sporophores, add calcium chloride 11.3 grams and 81 milliliters of mixture that are mixed with of 10% sodium hydroxide in the leachate, the leaching precipitate, add 6 equivalent hydrochloric acid and make resolution of precipitate for 31 milliliters, all the other technical processs are identical with embodiment 1, promptly get krestin.
