  • Method for the recovery of 12-(S)-hydroxyeicosapentaenoic acid from the red alga murrayella periclados
    Patent number: 4810424
    Abstract: 12-(S)-hydroxyeicosapentaenoic acid is chemically extracted from the red alga Murrayella periclados. Fresh or frozen quantities of Murrayella periclados are first macerated and combined with a 2:1 mixture of chloroform and methanol. This results in an organic fraction containing lipid isolates. After filtration to remove extraneous solids, the organic fraction is evaporated to produce a tar. The tar contains 12-(S)-HEPE which is further purified as desired.
