| titleOfInvention | A kind of method utilizing how horse rhzomorph broth extraction how horse rhzomorph crude product |
| abstract | The present invention relates to a kind of method utilizing how horse rhzomorph broth extraction how horse rhzomorph crude product, its processing step is: first by how horse rhzomorph fermentation liquid carries out plate-and-frame filtration, expansion drying obtains how horse rhzomorph does dreg, then using lower alcohol is that solvent extracts, gained lixiviating solution falling film concentration, flow out to no liquid, add water subsequently and be acidified to pH4.5～5, macroporous resin is used to carry out desolventing technology, carry out two stage countercurrent extractions afterwards, back extraction, last resin absorption, obtains how horse rhzomorph crude product after crystallization.Present invention achieves improve how horse rhzomorph yield, reduce cost, improve the preparation method of its crystal and end product quality, it is adaptable to industrialized production. |
