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 5 700 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 .展开更多
