Abstract

|
|
The ethanol- and water-extracts of curled tops and stalks of young bracken (Pteridium aquilinum) fronds in raw and cooked states were examined for their mutagenicity by Ames test using Salmonella typhymurium mutants. Even a small amount of water extract from raw bracken was mutageruc to TA 1538 strain without addition of S_9 mix whereas a strong toxicity appeared at higher levels of the extractive. With S_9 mix, the water-extract from raw bracken was not mutagenic at all and not toxic to all strains tested, The amount of water-extract from cooked bracken was one-tenth of the amount from raw bracken and the water-extract showed no mutagenic effect to all strains tested. Ethanol-extract of bracken showed no mutagenicity in any case.
