| Abstract: |
| The tocotrienols are a kind of natural vitamin E of high quality with wide development foreground and market demand. The sources of tocopherols and tocotrienols were introduced，the common separation and purification methods，the relevant technical route，the corresponding advantages and disadvantages and application scope of these methods and routes were emphatically introduced. The results showed that ion exchange method had high selectivity and specificity，which was suitable for extracting high content tocopherols and tocotrienols；the instrument equipment of column chromatography was simple，it was an effective method for the separation of tocopherols and tocotrienols in theory，but it had some problems such as long elution time and high solvent comsumption；supercritical fluid chromatograply had a good application prospect on preparing tocotrienols and its monomer. Finally，the industry situations of tocotrienols at home and abroad were introduced to provide references for further research of tocotrienols at home. |
