17. The structures of 5 and 6 were supported by the FAB MS/MS analyses. In the FAB MS/MS of 5, we could follow three major sequential fragments at m/z 617 (-Val), 466 (-Hmoya), 339 (-MeIle), and 242 (-Pro); 590 (-MeIle), 476 (-Hmpa), and 379 (-Pro); and 603 (-Hmpa), 476 (-MeIle), 377 (-Val), and 255 (-Hmoya). In case of 6, the sequential fragments were also observed at m/z 603 (-Val), 452 (-Hmoya), 325 (-MeIle), and 228 (-Pro); 576 (-MeIle) and 476 (-Hmba); and 603 (-Hmba) and 476 (-MeIle).
