借助于薄层层析（TLC闭高效液相层析（HPLC）方法，筛选确定了16株曲霉在玉米豆粉培养基SPMS上的杂色曲霉素（S）产量可达0－1160．3mg／kg。用高产杂色曲霉菌株进行ST产毒培养，液相革取ST，经硅胶柱层析和多次重结晶，纯化制备了2271．3mgST晶体。经品形观察，熔点测定，元素
TLC-blocked high performance liquid chromatography (HPLC) method was used to screen and determine 16 strains of Aspergillus versicolor (S) on corn flour medium SPMS with a yield of 0-1160.3 mg. The ST-producing culture was carried out with a high-yield strain of Aspergillus cholerae, ST was extracted from the liquid phase, and silica gel column chromatography and multiple recrystallizations were used to purify 2271.3 mg of ST crystals.
