本文报导的方法可同时检出玉米中5PPb 的黄曲霉毒素和200PPb 的赤霉烯酮。不需挥干溶剂,操作简单,以致可应用于仅有最简单实验室设备的市场。确定一件样品有无霉菌毒素仅需10—20分钟。操作步骤包括先用甲醇搀合提取,脂肪和色素从硫酸铵水层分配到1,1,2一三氯三氟乙烷(Freon-113)内,然后用氯苯从水相中提取霉菌毒素,氯苯提取液直接点于薄层板上,展开仅
The method reported here can simultaneously detect aflatoxin 5PPb and 200PPb zearalenone in corn. No solvent removal and ease of use make it suitable for markets where only the simplest laboratory equipment is available. Determine if a sample has mycotoxins in 10-20 minutes. The procedure involves first extraction with methanol, partitioning fat and pigment from the aqueous ammonium sulfate layer into 1,1,2-trichlorotrifluoroethane (Freon-113), and then extracting the mycotoxins from the aqueous phase with chlorobenzene , Chlorobenzene extract point directly on the TLC, expand only
