人参三肽的序列分析

Sequential Analysis of Tripeptide from Panax ginseng

采用Sephadex LH-20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.

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