摘要: 以自行合成的丁二酰亚胺羧酸活性酯类试剂N-羟基琥珀酰亚胺-α-萘乙酸酯为柱前衍生试剂,用反相高效液相色谱分离测定了谷胱甘肽、三甘肽、二甘肽及谷氨酸、胱氨酸、甘氨酸,在C18柱上,采用的流动相为含15mmol/L、pH=5.4的醋酸-醋酸钠缓冲溶液和3%的乙酸乙酯的甲醇-水(17/80,体积比)溶液,16min内6种衍生物得到完全分离,当信噪比为3:1时,检测限达pmol级,重现性良好。

Abstract: Using N-hydroxysuccinimidyl-α-naphthylacetate(SINA,synthesized by ourselves) as pre-column derivating reagent,glutathion,diglxcyl-glycine,glycyl glycine, Glu,(Cys)2 and Gly were separated and determined by reversed phase high performance liquid chromatograph (RP-HPLC).The six derivatives were eluted within 16min with a mobile phase of methanol-acetic ether-water(17/3/80 ,volume ratio)containing 15 mmol/L pH=5.4 acetate buffer on C18 column,At the ratio of signal to noise S/N=3,the detection limit is in lower picornole range,The reproducibility was good.

Key words: High performance liquid chromatograph, N-Hydroxysuccinimidyl-α-naphthylacetate, peptides and their hydrolysates
