From a strain of Streptomyces antibioticus seven yellow phenazines were isolated. The antibacterially most active antibiotic was identified as (-)-saphenamycin, a second one with compound DC-86-Y (saphenic acid). Three compounds were new: Saphenic acid methyl ether, 6-acetylphenazine-1-carboxylic acid and an inseparable mixture of fatty acid esters of saphenic acid. Two simple phenazines were phenazine-1-carboxylic acid (tubermycin B) and unsubstituted phenazine, which was isolated for the first time from a microorganism.
从一株抗生链霉菌中分离出了七种黄色吩嗪。抗菌活性最强的抗生素被鉴定为（-）-萨芬霉素，另一种是化合物DC-86-Y（萨芬酸）。有三种化合物是新的：萨芬酸甲酯、6-乙酰吩嗪-1-羧酸以及萨芬酸脂肪酸酯的不可分离混合物。两种简单的吩嗪是吩嗪-1-羧酸（结核霉素B）和未取代的吩嗪，后者是首次从微生物中分离得到。
