| titleOfInvention | Method for extracting astaxanthin diester from antarctic krill |
| abstract | The invention discloses a method for extracting astaxanthin diester from antarctic krill, which comprises the following steps of: adding n-hexane into dried antarctic krill, stirring, extracting and filtering; carrying out rotary evaporation on filtrate to remove n-hexane to obtain red shrimp sauce; adding acetone into the red shrimp sauce for dissolving, and filtering to obtain acetone extract; carrying out rotary evaporation for removing acetone to obtain a red shrimp sauce sample containing the astaxanthin diester; dissolving the red shrimp sauce sample by petroleum ether for standby; taking a chromatographic column, packing, loading the red shrimp sauce sample and eluting to obtain a yellow strip; and carrying out rotary evaporation for removing solvent to obtain the astaxanthin diester. The method for extracting the astaxanthin diester from the antarctic krill adopts n-hexane and acetone for extracting and the column chromatography for preparing the astaxanthin diester, and is less in dosage of the solvent as well as simple and easy in technical process, thus providing technical reference for extracting the astaxanthin diester from the antarctic krill. |
