The structures of aspertetronin A (C16H20O4) and aspertetronin B (C16H22O5), metabolites of a mutant strain of Aspergillus rugulosus, have been elucidated. The use of both high-resolution 1H n.m.r. spectroscopy (220 Mc./sec. and spin decoupling) and ‘element-map’ mass spectrometry have proved determining in establishing that the metabolites are the novel acyltetronic acid derivatives (XXII) and (XXIII)
已阐明了曲霉曲霉突变菌株的代谢产物曲霉精A(C 16 H 20 O 4)和曲霉精B(C 16 H 22 O 5)的结构。事实证明,高分辨率1 H nmr光谱(220 Mc./sec和自旋解耦)和“元素图”质谱法的使用确定了代谢产物是新型的酰基电子酸衍生物(XXII)和(XXIII) ) 分别。
