Method for selective separation of free-astaxanthin from green algae haematococcus pluvialis

摘要: There is provided a method of separating free-astaxanthin selectively from green algae and, more particularly, to Haematococcus pluvialis, the comprising: mixing cell culture containing pluvialis with an alkanic solvent and stirring, thereby obtaining extract astaxanthin material including ester (step 1); alcohol alcoholic 2). The present invention can not only maximize efficiency in high concentration by providing very simple process technique capable recovering H. efficiency, but also realize economical operation repeatedly using as mediating for extracting free-astaxanthin. Such separation be used carotinoid analogue useful microalgae addition species.
