B. Ellis. We used shaking culture in a modified Fries culture medium and methanol extraction to isolate the toxin. The optimal developing solvent mixture （methanol： ethyl acetate： H20 at 7：1.5：3） was selected using thin layer chromatography and used as the eluent for toxin purification by silica gel column chromatography. Two toxic fractions were identi- fied in the bioassay. A flaxen oil substance, AP-I, showed higher toxicity than a toxic white powder, AP-II. The more toxic AP-I was determined to be dibutyl phthalate （C16H2204, molecular weight of 278） by mass spectrome- try, nuclear magnetic resonance, and infrared spectropho- tometry. Dibutyl phthalate might contribute to the pathogenesis of bamboo blight.展开更多
