A process for obtaining gangliosides from mammalian nervous tissue, comprises the step of:-
(a) extracting the nervous tissue using at least one (C₁-C₄) alcohol and at least one non-polar organic solvent,
(b) filtering the mixture and adding water to the filtrate to produce an aqueous alcoholic phase,
(c) adsorbing gangliosides present in said aqueous alcoholic phase on an ion exchange material, and then washing the ion exchange material with a ketone,
(d) recovering the gangliosides from the ion exchange material using a solvent mixture including water, (C₁-C₄) alcohol(s), organic solvent(s) and alkali(es),
(e) purifying the material recovered from the ion exchange material by partition or absorption column chromatography, and
(f) recovering the extracted gangliosides from the chromatography column.
一种从哺乳动物神经组织中获取神经节苷脂的工艺,包括以下步骤
(a) 使用至少一种(C₁-C₄)醇和至少一种非极性有机溶剂提取神经组织、
(b) 过滤混合物并向滤液中加水,以产生含水酒精相、
(c) 将所述水醇相中的神经节苷脂吸附在离子交换材料上,然后用酮清洗离子交换 材料、
(d) 使用包括水、(C₁-C₄)醇、有机溶剂和碱在内的混合溶剂,从离子交换材料中回收神经节苷脂、
(e) 通过分配或吸收柱色谱法纯化从离子交换材料中回收的材料,以及
(f) 从层析柱中回收提取的神经节苷脂。
