Abstract

A single pure component was isolated from mycobactin P by countercurrent distribution; its side chain is n-cis-octadec-2-enoyl; its purity and molecular structure were confirmed by mass spectrometry of its aluminium complex. The separation of ferric and of aluminium complexes of mycobactins by thin-layer chromatography is described. Mycobacterium terrae, M. marinum and M. smegmatis produce mycobactins that differ among themselves and from mycobactins P and T. A nomenclature for the mycobactins and their derivatives is suggested.

摘要

通过逆流分配法从分枝杆菌素P中分离出单一纯组分;其侧链为正顺式十八碳-2-烯酰基;通过其铝络合物的质谱法确定了其纯度和分子结构。描述了通过薄层色谱法分离分枝杆菌素的铁络合物和铝络合物。地分枝杆菌、海分枝杆菌和耻垢分枝杆菌产生的分枝杆菌素彼此不同,且与分枝杆菌素P和T也不同。提出了分枝杆菌素及其衍生物的命名法。
