摘　　要：提出了将麦迪霉素与镁的络合物萃入甲基异丁酮（ＭＩＢＫ），火焰原子吸收法测定有机相中镁，从而间接求得麦迪霉素含量的方法．测定线性范围为５０～５００μｇ／ｍＬ，回收率９３％～１０４％，相对标准偏差３％以内，测定结果令人满意．Method to determine the content of midecamycin in directly is proposed,in which the complex compund that midecamycin react with magnesium are extracted with MIBK at pH4.0,and then the Mg in organic phase is determined with FAAS. The linear range is 50￣500 μg/mL. The recovery rate is 93%￣104%. The relative standard deviation is 3%. The proposed method has been applied to determine midecamycin with satisfactory results.
