Litorin-like peptides in the skin of five phyllomedusa species other than Phyll.sauvagei and Phyll.rohdei.
Methanol extracts of the skin of five Phyllomedusa species, other than Phyll. sauvagei and Phyll.rohdei, were estmined to check their content in litorin-like peptides. Extracts of Phyll.bicolor and Pachymedusa dacnicolor did not contain appreciable amounts of litorin-like activity. However, extracts of Phyll. burmeisteri presented a typical phyllolitorin-like activity and extracts of Phyll.hypochondrialis an activity mimicking that of rohdei-litorin. A particular position is taken by extracts of Phyll.trinitatis, which displayed a litorin-like activity differing, in parallel bioassay, from that of all known natural litorins.
