title: Litorin-like peptides in the skin of five phyllomedusa species other than Phyll.sauvagei and Phyll.rohdei.
abstract: 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.
