摘要: The Rana temporaria chensinensis is an amphibian distributing mainly over the north of China. Its skin gland contains a variety of peptides, including antibacterial peptides. One of them, component 1, has been purified from the dried skin of R.temporaria chensinesis using a five-step procedure. Purified component 1 has a molecular weight of 5700 and its amino acid composition shows that it is devoid of disulfide bridges but rich in histine and glycine residues. Moreover, it has been found that it has a broad spectrum of antibacterial activity for Pseuctomonas aeruginosa, Escherichia coli, Bacillus sublilis, S. faccalis and Proteus vulgaris .
