The phytopathogenic fungus Alternaria eichorniae attacks water hyacinth, an economically significant aquatic weed. The novel phytotoxin alteichin was isolated from liquid cultures of this fungus and its structure was deduced by X-ray crystallographic analysis. Altheichin is a doubly hydrated form of 4,9-dihydroxy perylene-3, 10-quinone. A single step dehydration of alteichin to anhydroalteichin is catalyzed both by acid and by a crude enzyme preparation from water hyacinth.
植物病原真菌凤眼莲链格孢侵袭凤眼莲，这是一种具有经济重要性的水生杂草。从该真菌的液体培养物中分离出了新型植物毒素凤眼莲链格孢菌素，并通过X射线晶体学分析推导其结构。凤眼莲链格孢菌素是4,9 - 二羟基苝-3,10 - 醌的双水合形式。凤眼莲链格孢菌素向脱水凤眼莲链格孢菌素的单步脱水反应可由酸和凤眼莲的粗酶制剂催化。
