The amino acid sequence of the bioactive peptide PCT-1 is LNRTFE, as shown in SEQ ID NO: 1, and the bioactive peptide PCT-1 has antioxidant and intestinal flora-regulating functions. Extracted from spirulina protein peptides, the bioactive peptide PCT-1 can significantly increase the activities of SOD and GSH-Px in serum, and significantly reduce the content of MDA in serum; its in vivo antioxidant activity is comparable to that of the positive control Trolox. Meanwhile, compared with the blank control group, the bioactive peptide PCT-1 can also reduce the ?-diversity index of intestinal flora, change the overall structure of intestinal flora, regulate the abundance of intestinal flora at various taxonomic levels, and significantly increase the contents of acetic acid and butyric acid. Therefore, the bioactive peptide PCT-1 can be applied in functional foods for antioxidation and intestinal flora regulation.
