Detailed view of on-line LC-MS/MS analyses performed for the analyses of the skin secretion of R. schneideri ((a) zoomed TIC chromatogram and (b) MS and MS² profiles) and R. jimi ((c) zoomed TIC chromatogram and (d) MS and MS² profiles). The molecules could be identified as being dehydrobufotenine and hellebrigenin based on the daughter ions and published results.
