A tandem organic solvent system for selective extraction of free-astaxanthin from Haematococcus pluvialis

摘要：

A tandem solvent process of dodecane and methanol was developed for the selective extraction of free-astaxanthin from red encysted Haematococcus culture. The process consists of dodecane extraction for astaxanthin mixture from the culture (stage 1) and methanol extraction for free-astaxanthin from the dodecane extract (stage 2). In the second stage, free-astaxanthin was selectively collected to methanol from the dodecane extract, accompanied with saponification of astaxanthin-esters by the addition of NaOH to methanol, resulting in a total recovery yield of free-astaxanthin of over 85％.
