神经节苷脂的分离与纯化是研究组织细胞Gls组成、含量及代谢的基本手段.但是以往的方法周期长、溶剂用量大,为此建立了一种新的微型离心柱快速分离Gls纯化法,标准Gls的回收率为97.64%,n=7,CV<3%,HPTLC图谱显示无丢带现象.纯化样品只需十几个小时,操作简单,溶剂用量小,重复性好,为微量样品组分的研究提供了一个有效的手段.
A simple and rapid method for isolation and purification of gangliosides (Gls) from the rat brain is described. The gangliosides were isolated and purified by centrifugal mini-column chromatography. The rate of recovery of standard Gls was up to 97.64%, n=7, CV<3%. No detective loss of Gls was demonstrated. The novel method offers a few advantages: 1.It is simple, rapid and efficient. 2.The thin layer chromatographic patterns of total Gls of samples obtained are clear and distinct. 3.Less solvent was consumed. Thus, the method is especially applicable to comparative and qualitative studies of gangliosides of micro samples, and to ganlioside metabolism research of tissues and cells in vitro.
