Isolation of an active glucoside in bracken fern, Pteridium aquilinum.
An active glucoside that enhanced release of histamine from rat peritoneal mast cells was isolated from a toxic fraction of bracken fern, Pteridium aquilinum, by partition column chromatography on Sephadex G-25. It was a yellowish amorphous powder on freeze-drying, readily soluble in water or ethanol, and insoluble in ether. It was hydrolysed with beta-glucosidase to release D-glucose. It was a...
متن کاملCarcinogenic and mutagenic activities of milk from cows fed bracken fern (Pteridium aquilinum).
Carcinogenicity, toxicity, and mutagenicity of the milk of bracken fern (BF)-fed cows were determined. Four Brown Swiss cows were fed a BF-containing diet, and two cows were fed a normal hay-grain diet. The milk obtained was fed to rats as either fresh or freeze-dried powdered milk mixed with grain diet: 9 of 34 fed whole milk and 11 of 56 fed powdered milk diet developed small intestine, kidne...
متن کاملTumor induction in germ-free rats fed bracken (Pteridium aquilinum).
This study indicated that there was no significant difference in the incidence of intestinal tumors between germ-free and conventional rats fed a diet containing bracken, suggesting that gut microflora did not play a definite role in bracken tumorigenesis. However, bracken induced exclusively sarcoma but no adenocarcinoma in germ-free rats, whereas it induced predominantly adenocarcinoma in con...
متن کاملBracken (Pteridium aquilinum); the effect of steaming on the nutritive value of bracken hay.
The bracken fern (Pteridium aquilinum) has been known for a long time to be poisonous to cattle (Penberthy, 1893) and horses (Muller, 1897) under farm conditions. Field cases of bracken poisoning in sheep are almost unknown; the more selective feeding habits of sheep may be responsible for their apparent immunity. Bracken poisoning has been experimentally produced in cattle (Almond, I 894), hor...
متن کاملEffectiveness of Current Methods for the Control of Bracken (pteridium Aquilinum)
Background Control of bracken (Pteridium aquilinum) is a global problem for livestock-based extensive agriculture, conservation, recreation, game management and forestry. Bracken is controlled primarily by application of asulam or by cutting. The success of bracken control may be dependent upon ecological variables (such as habitat type and latitude) and methodological variables (such as number...
