A number of studies have been conducted to identify the carcinogenic agent(s) in bracken fern (Evans, 1976; Hirono, 1981; Pamukcu and Bryan, 1979). quercetin (3,3',4',5,7-pentahydroxyflavone) occurs as a conjugate in bracken fern and in numerous other plants. In culture, this compound has induced morphological transformation of cryopreserved golden hamster embryo cells (Umezawa et_ al_. , 1977) and mutations in S_. typhimurium (Bartholomew and Ryan, 1980), but its carcinogenicity in rats continues to be disputed. In one study, administration of 0.

When added to the diet of A/HeJ mice subsequently challenged with orally administered BaP, 6-naphthoflavone caused almost total inhibition of pulmonary adenoma formation, and quercetin pentamethyl ether reduced the number of these neoplasms by one-half. The number of adenomas was the same in animals fed rutin and the control diet. Thus, the inhibitory effects of BaP-induced neoplasia paralleled the potency of the three flavones in inducing increased AHH activity (Wattenberg and Leong, 1968, 1970).
