Extraction of functional lipids including eicosapentanoic acid (EPA) from Nannocchloropsis sp. Was carriedout for ultrasonic extraction, impregnant extraction, and supercritical carbon dioxide extraction with/without ethanol co-solvent. Among the three extraction methods, ultrasonic extraction with both Folch solvent andethanol ledto effective lipidextraction. Although the supercritical fluidextraction with/without ethanol co-solvent gave a low extraction yieldof total lipids, EPA was highly concentratedin the extractedtriglycerid es.
