| titleOfInvention | A kind of method that allantoin is prepared in the oligosaccharide syrup from saline cistanche |
| abstract | The present invention relates to a kind of method that allantoin is prepared in oligosaccharide syrup from saline cistanche, methods described, through charcoal absorption, hydrolysis suction, alcohol precipitation and crystallization, the supernatant after crystallization is dried, obtains the allantoin using saline cistanche oligosaccharide syrup solution as raw material.The present invention is by being eluted with water activated carbon, then obtained eluent is concentrated, alcohol precipitation, and by supernatant concentration, crystallization, after the supernatant after crystallization is dried, you can obtain the allantoin of the present invention.Method provided by the present invention abandoned it is conventional by the way of ethanol elution, by using hydrolysis inhale so that technique is simpler, reduces cost, realizes maximally utilizing for resource, is easy to industrialized production. |
