摘要：
PURPOSE: Provided is a method for preparing DHA(docosahexaenoic acid) and EPA(eicosapentaenoic acid) useful for food additives, which uses Lingulodinium polyedrum as a starting material to produce DHA and EPA with high purity and high yield. CONSTITUTION: The method for preparing DHA and EPA uses a dry product containing DHA and EPA obtained by freeze drying Lingulodinium polyedrum, which is dinoflagellate. The method comprises the steps of: extracting the dry product with a mixed solvent; evaporating the organic solvent layer under reduced pressure and purifying the resultant product by chromatography, or evaporating the solvent under reduced pressure and extracting the resultant residue with lower alcohol/C6-8 alkane solvent, so that fractions of lower alcohol layer can be obtained; evaporating the fractions to remove the solvent; extracting the resultant residue with ethyl acetate/water to obtain the ethyl acetate layer; mixing the ethyl acetate layer with the C6-8 alkane layer; evaporating the resultant mixture under reduced pressure and purifying the residue by chromatography.
摘要（中）：
目的：提供一种可用于食品添加剂的DHA（二十二碳六烯酸）和EPA（二十碳五烯酸）的制备方法，该方法以高纯度和高产率生产DHA和EPA为起始原料。 构成：用于制备DHA和EPA的方法使用含有DHA和EPA的干燥产品，其通过冷冻干燥葡萄柚多糖得到。 该方法包括以下步骤：用混合溶剂萃取干燥产物; 在减压下蒸发有机溶剂层，通过色谱法纯化所得产物，或在减压下蒸发溶剂，并用低级醇/ C6-8烷烃溶剂萃取所得残余物，从而可得到低级醇层级分; 蒸发馏分以除去溶剂; 用乙酸乙酯/水萃取所得残留物，得到乙酸乙酯层; 将乙酸乙酯层与C6-8烷烃层混合; 在减压下蒸发所得混合物并通过色谱法纯化残余物。
