来自 Asp 的菌丝体。尼日尔和天冬氨酸。泡盛 aurasperones A、B 和 C 以及相关的两种黄色色素已被分离出来。 Aurasperone A，C32H26010，为黄色棱晶；米。 p。 207℃； [α]D-136°；得到二乙酸酯和二甲醚，并假定为二聚体2-甲基-5-羟基-6, 8-二甲氧基-4H-萘并[2, 3-b]吡喃-4-酮(IV)。 Aurasperone B，[α]D+46.3°，是主要的黄色代谢物，m。 p。 186℃，经盐酸处理得到aurasperone A。它的分子式为C32H30012，推测具有结构(V)。已发现其他黄色颜料也是 aurasperone A 的同系物。
From mycelia of Asp. niger and Asp. awamori aurasperones A, B and C along with related two yellow pigments have been isolated. Aurasperone A, C32H26010, is obtained in yellow prisms; m. p. 207°C; [α]D-136°; gives the diacetate and the dimethyl ether and is assumed to be a dimeric 2-methyl-5-hydroxy-6, 8-dimethoxy-4H-naphtho [2, 3-b] pyran-4-one (IV). Aurasperone B, [α]D+46.3°, is the main yellow metabolite, m. p. 186°C, and affords aurasperone A on hydrochloric acid-treatment. It has molecular formula C32H30012 and is supposed to have the structure (V). The other yellow pigments have been found to be also congeners of aurasperone A.
