After ether extraction of the acidified broth, a water- 

 soluble derivative of fusarubin remains behind. This has 

 been identified as a sulfate ester occurring at one of the 

 hydroquinone hydroxyl groups and was called fusarubino- 

 gen. Fusarubinogen actually is present in the broth in a 

 reduced form, which is probably a derivative of ^-hydro- 

 naphthazarin.
