title: Two interchangeable forms of ciguatoxin.
abstract: Ciguatoxin, the principal toxin responsible for ciguatera, isolated from moray eel viscera, has been separated into two distinct components by alumina chromatography. A series of chromatographies showed that the two components are interchangeable. This proves that ciguatoxin is a single molecular entity. Both forms were crystallized and their 1H NMR spectra were recorded.
