从海洋真菌曲霉CRI323-04中分离出了一种新的酪氨酸衍生代谢物曲霉酚A(4),以及4-羟苯基丙酮酸肟(5)和乙醛酸A的克级克。。在四醇4是由比较确定为赤藓糖醇1个其苯甲酰衍生物与苯甲酰化赤藓醇(的1 H NMR光谱7)和d -threitol(8),以及由基于纤维素的手性HPLC分析。曲霉酚A(4)选择性抑制酵母酿酒酵母中的α-葡萄糖苷酶,但对嗜热脂肪芽孢杆菌的α-葡萄糖苷酶无活性。
A new tyrosine-derived metabolite, aspergillusol A (4), was isolated on a gram scale, together with a methyl ester of 4-hydroxyphenylpyruvic acid oxime (5) and secalonicacid A, from the marine-derived fungus Aspergillusaculeatus CRI323-04. The tetraol in 4 was identified as erythritol by comparison of the 1H NMR spectrum of its benzoylated derivative with those of benzoylated erythritol (7) and d-threitol
