摘　　要：采用凝胶层析对乳酸菌粗提液进行分离、纯化，得到乳酸菌肽纯化样品，对其含量、纯度及抑菌效果等指标进行了测定．得到纯化时间在14～18h所收集的样品含量最高、纯度最高、抑茼效果最好。从而获得了重要的乳酸菌肽研究资料．为今后更进一步的研究打下基础。Crude extracted solution of Lactobacillus was separated, and purified using gel chromatography to obtain purified Lactobacillus peptide （Lp） sample. Its contents, purity, and inhibition effect against bacteria, and other targets were determined. The results showed that 1418 hour after the purification the collected sample possessed the highest content, the highest purity, and the best inhibition effect. Therefore, important research data of Lp were obtained, and laid a good foundation for further study in the days to come.
