Structures of a New Dihydroxanthone Derivative, Nidulalin A, and a New Benzophenone Derivative, Nidulalin B, from Emericella nidulans.
摘要:
从Emericella nidulans var. lata水稻培养物提取物中分离出两种新化合物,分别命名为nidulalins A (1)和B (2),以及emestrin和sterigmatocystin。通过化学和光谱研究、X射线晶体学研究和改良的Mosher法,确定了nidulalins A (1)和B (2)的结构。
Two new compounds, designated nidulalins A (1) and B (2), were isolated along with emestrin and sterigmatocystin from the extract of rice culture of Emericella nidulans var. lata. The structures of nidulalins A (1) and B (2) were determined on the basis of chemical and spectroscopic investigation and X-ray crystallographic study, together with the application of the modiifed Mosher's method.
