从一种被称为“大豆紫斑病”病原体的真菌——菊椒丝孢菌（Cercosporina kikuchi M. et T.）培养的菌丝体中分离出一种色素，cercosporin，产量很高。其分子式为C30H28O10，存在两个甲氧基、几个酸性羟基和类醌体系。介绍了真菌的培养条件和色素的分离、纯化及一般性质。1924年，菊池1表明，被认为是一种遗传性疾病的“大豆紫斑病”是由一种属于Cercospora物种的真菌引起的。1925年，Matsumoto和Tomoyasu2·3证实了菊地的观察结果，随后将这种真菌命名为Cercosporina Kikuchi Matsumoto et Tomoyasu。虽然对这种真菌进行了病理和农艺研究，但对其产生的色素却没有引起重视。作者已经能够从Cercosporina的干菌丝体中分离出一种深红色的色素
A pigment, cercosporin, has been isolated in good yield from the cultured mycelia of Cercosporina Kikuchii M. et T., a fungus known as a pathogen of “soy bean purple speck disease.” Its molecular formula is C30H28O10, and the presence of two methoxy, several acidic hydroxyl groups and the quinoid systemhas been established. Conditions for the culture of the fungus and the isolation, purification and general properties of the pigment are described.In 1924 Kikuchi1 showed that the" soy bean purple speck disease" which had been considered to be an hereditary disease, was caused by a fungus belonging to the Cercospora species. In 1925 Matsumoto and Tomoyasu2· 3 confirmed Kikuchi’s observation and the fungus was subsequently named Cercosporina Kikuchii Matsumoto et Tomoyasu. Although pathologicaland agronomical studies of this fungus have been reported, no attention has been paid to the pigments produced. The authors havebeen able to isolate a deep red pigment from the dried mycelia of Cercosporina
