| titleOfInvention | A kind of isolation and purification method of N-acetylation shell six sugar of different acetyl degree |
| abstract | The invention belongs to Marine Chemistry engineering, be specifically related to a kind of isolation and purification method of N-acetylation shell six sugar of different acetyl degree. First preparing complete deacetylated shell six sugar is raw material; be dissolved in methanol/water solution; add and under a certain amount of acetic anhydride room temperature, carry out acetylation modification and obtain N-acetylation shell six sugar mixtures; then do you mixture be used to ion-exchange chromatography CM? Sephadex? C-25 or CM? Sepharose? Fast? Flow is with the NaCl solution of 0-2M concentration at pH3-6, and flow velocity is 2-5mLmin -1 Condition under carry out separation and purification; collect eluent; elution fraction is concentrated after activated carbon extraction desalination respectively; obtain different acetyl degree N-acetylation shell six sugar; the present invention, taking complete deacetylated shell six sugar as raw material, adopts ion-exchange chromatography to separate N-acetylation shell six sugar that obtain six kinds of different acetyl degree, has the advantages that flow velocity is fast, resolution ratio is high, productive rate is high; and separating step is few, only separates and just can obtain different acetyl degree N-acetylation shell six sugar through a step. |
