The structures of hynapenes A, B and C, novel anticoccidial agents, were determined by spectroscopic analyses. Hynapenes A, B and C were deduced to be (2E, 4E)-5-(1, 3, 4-trihydroxy-2, 6, 8-trimethyldecalin)-2, 4-pentadienoic acid, (2E, 4E)-5-(1-ene-3-oxo-2, 6, 8-trimethyldecalin)-2, 4-pentadienoic acid and (2E, 4E)-5-(3-ene-1-oxo-2, 6, 8-trimethyldecalin)-2, 2, 4-pentadienoic acid, respectively.
