Two new trichothecenes, 8-n-pentanoylneosolaniol and 8-n-hexanoylneosolaniol, were isolated from corn grits cultured with Fusarium sporotrichioides. The structures of these compounds were elucidated using gc-ms, nmr, X-ray crystallography, and other spectroscopic techniques. Seven known trichothecenes were also isolated, and the relative cytotoxicity of these nine trichothecenes in cultured baby hamster kidney (BHK-21) cells was determined.
