Abstract: The host-specific pathotoxin complex isolated from the culture filtrate and mycelial mat of Bipolaris (Helminthosporium) maydis, race T, was reduced to hydrocarbons. The hydrocarbons were separated by molecular sieves and analyzed by GC-MS. The MS gave typical spectra of normal, odd carbon numbered hydrocarbons from C35H72 to C49H100. Compounds differing from hydrocarbons only in the presence of an internal tetrahydropyran ring were obtained as by-products from the toxin-complex reductions. These compounds were analyzed by Cl (chemical ionization)-GC-MS and HR (high resolution)-GC-MS. The MS data supported the hypothesis that the C35- to C49- toxins are analogous compounds with many common partial structures. The configurations at both the C-6 and C-8 carbons of the major components appeared to be R.
