Three new linearpeptides containing d-leucine, named whitmantides A-C (1-3), were isolated from the dried whole bodies of Whitmania pigra Whitman. Their structures with absolute configurations were elucidated by Edman degradation, mass spectrometry, Marfey's analysis, and solid-phase synthesis. It is the first time that peptides containing d-amino acid in leeches were discovered. Compounds 1-3 displayed
