Antimicrobial activity was discovered in the expressed and concentrated juices of buckwheat, and in the water soluble fractions of hot extracts using organic solvent(s). A phenolic chromogenic substance was found to be responsible for the antibiosis of the extracts. The degradatory products of the anthocyanin pigment from the plant were shown to have somewhat similar toxicities to those of the extracts. The organic acids, citric, malic and oxalic, reported present in appreciable quantities in the plant, were also assayed for antimicrobial properties, and were found to be somewhat more toxic than the phenolic substances. It was not possible to draw a definite relationship between the above antimicrobial properties, and the actual non-susceptibility of the plant to microbial attack.
