Fern, bracken

The toxic properties of Pteridium aquilinum L., the common bracken fern, have been known to humankind for a very long time. Two principal causes of trouble are its carcinogenic properties (M. Saito et al., 1975 I. A. Evans, 1976 Hirono, 1986)... [Pg.219]

A review on the isolation, chemistry, and biochemistry of the bracken fern (Pte-ridium aquilinum) carcinogen ptaquiloside (P) has been published (527). This fem and others contain the pterosins that were summarized previously (7). No new examples were reported in the interim. [Pg.44]

A great deal of natural variability often is present in a fungal population. Webb and Lindov ( ) found isolates of Ascochvta Dteridis (Bres.) Sacc. from bracken fern (Pteridium aquilinum (L.) Kuhn) to vary in virulence, spore production, and tolerance to desiccation. Isolates of biocontrol fungi are routinely screened for desired characteristics such as increased virulence, abundant spore production, and environmental tolerance (1 ,. ... [Pg.181]

In people whose thiamin intake is marginal, colonization of the gastrointestinal tract with thiaminolytic microorganisms may be a factor in the development of beriberi. The thiaminases present in raw fish can result in so-called Chastek paralysis of foxes and mink, as a result of destruction of thiamin, and may be important in parts of the world where much of the apparent thiamin intake is from fish that is eaten raw or fermented. The polyphenols and thiami-nase in bracken fern can cause thiamin deficiency (blind staggers) in horses, and tannic acid in tea and betel nut have been associated with human thiamin deficiency. [Pg.166]
