In: Agricultural and Biological ChemistrySummary: Bluish fluorescent and phenolic components were produced in cassava roots in response to cut injury, and in relation to physiological and microbial deterioration. The former proved to consist of 5 coumarin components, the main 3 of which were scopoletin, scopolin, and esculin, and the other 2 were scopoletin- and esculetin-containing conjugates. A main component of the latter was (+)-catechin. Some enzymes pertaining to the production of the secondary metabolites such as acid invertase, phenylalanine ammonia lyase, and peroxidase were formed in cut-injured tissue and in noninfected tissue adjacent to the soft rotten part.
