摘要	The sea cucumber (Stichopus japonicus) was continuously hydrolyzed by pepsin, trypsin to get sea cucumber peptides (SCP), and low molecular peptides (LSCP), MW < 3000 Da, were collected through an ultrafiltration membrane with a molecular weight cut-off of 3000 Da Two main fractions, LSCP-1 and LSCP-2 were obtained by one step gel filtration column chromatography. Furthermore, the antitumor activities, in vitro, of LSCP-1 and LSCP-2 fractions were evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay. LSCP-2 showed significantly antitumor activity against the SGC-7901 and MCF-7 cell lines, LSCP-1 showed significantly antitumor activity only against SGC-7901 cell line, and two fractions did not show activity against A549 cell line. Overall, this study indicated that LSCP posseses potential to treat gastric cancer and breast cancer.
