Tentoxin is a natural cyclic tetrapeptide produced by phytopathogenic fungus "Alternaria alternata". It selectively induces chlorosis in several germinating seedling plants. Therefore, tentoxin may be used as a potential natural herbicide.

Tentoxin was first isolated from "Alternaria alternata" (syn. "tenuis") and characterized by George Templeton "et al." in 1967. [Templeton, G. E., C. 1. Grable, N. D. Fulton, W. L. Meyer. 1967. Tentoxin from Alternaria tenuis: its isolation and characterization. "Proceedings of the Mycotoxin Research Seminar, Washington, D. C.", June 8-9, 1967. United States Department of Agriculture. pp. 27-29]

Tentoxin has also been used in recent research to eliminate the polyphenol oxidase (PPO) activity from seedlings of higher plants. [Duke, S.O. & Vaughn, K.C. 1982. Lack of involvement of polyphenol oxidase in ortho-hydroxylation of phenolic compounds in mung bean seedlings. "Physiol. Plant. 54:" 381-385.]
