摘要:

采用Sephadex LH20色谱柱, 以体积分数10%的甲醇为流动相分离人参中具有增强记忆活性的肽类成分, 通过高效液相色谱系统将其纯化, 并用蛋白质测序仪分析其氨基酸序列. 结果表明,  所得序列为Gln-Thr-Ser的新三肽.

关键词: 人参, 氨基酸, 序列分析, 三肽

Abstract:

The peptides, which show enhanced memory effect, from Panax ginseng were separated on a Sephadex LH20 column, the mobile phase was volume fraction 10% of methanol, and purified by HPLC. Then the amino acid sequence was analysed by protein sequencer. The results of amino acid sequential analysis showed that a novel tripeptide whose amino acid sequence is GlnThrSer was obtained.

Key words: Panax ginseng, amino acid, sequential analysis, tripeptide
