| titleOfInvention | A kind of method for crystallising of 1-DNJ |
| abstract | The invention discloses a kind of method for crystallising of 1 1-Deoxynojirimycin, this method includes：First mulberry leaf powder with acidic ethanol is impregnated, and is handled in ultrasonic cell-break machine, is filtered, is collected filtrate and be centrifuged, crude extract is made；By cation exchange resin, eluted；Collection eluent, which is placed in Rotary Evaporators, to be concentrated, then concentrate is extracted with n-butanol；Extract liquor is recycled after extraction, excess is placed in low temperature drying case and is dried；Drying is placed in ethyl alcohol, and crystal is precipitated after forming supersaturated solution, is got product after collecting crystal drying.The method for crystallising of 1 1-Deoxynojirimycin provided by the invention can obtain about 0.2% 1 DNJ recovery rates of mulberry leaf, it is significantly higher than traditional ethyl alcohol recovery rate 0.00139%, and diluted acid extraction efficiency 0.00147%, illustrate that diluted acid and ethyl alcohol are acted synergistically in 1 DNJ of mulberry leaf is extracted, produce unpredictalbe effect. |
