This procedure is used for large-scale purification of -coronafacoyl phytotoxins that are produced by the potato common scab pathogen . The procedure employs organic extraction of culture supernatants under alternating basic and acidic conditions in order to preferentially isolate the phytotoxin - containing carboxylic acid fraction of the supernatant. Preparative thin layer chromatography and semi-preparative reverse phase - high performance liquid chromatography are then used to further purify the individual -coronafacoyl phytotoxins of interest.
该程序用于大规模纯化由马铃薯疮痂病病原体产生的冠菌素类植物毒素。该程序采用在交替的碱性和酸性条件下对培养上清液进行有机萃取,以便优先分离出上清液中含植物毒素的羧酸部分。然后使用制备型薄层色谱和半制备型反相高效液相色谱进一步纯化目标冠菌素类植物毒素。
