Ptaquiloside in Irish Bracken Ferns and Receiving Waters, with Implications for Land Managers.
Ptaquiloside, along with other natural phytotoxins, is receiving increased attention from scientists and land use managers. There is an urgent need to increase empirical evidence to understand the scale of phytotoxin mobilisation and potential to enter into the environment. In this study the risk of ptaquiloside to drinking water was assessed by quantifying ptaquiloside in the receiving waters ...
متن کاملGenotoxic activity and inhibition of soil respiration by ptaquiloside, a bracken fern carcinogen.
Ptaquiloside (PTA) is a natural toxin produced by bracken (Pteridium aquilinum [L.] Kuhn). Assessment of PTA toxicity is needed because PTA deposited from bracken to soil may leach to surface and groundwater. Inhibition of soil respiration and genotoxic activity of PTA was determined by a soil microbial carbon transformation test and an umu test, respectively. In the carbon transformation test,...
متن کاملMass spectrometric analysis of ptaquiloside, the toxic sesquiterpene from bracken fern.
latiusculum); its structure was elucidated in 1987. The same substance and several analogues have been identified in other Pteridacae. Bracken fern is currently consumed by farm animals, and this causes a number of well-known syndromes in domestic animals. In large ruminants, chronic enzootic haematuria, the clinical expression of multiple neoplasia of the urinary bladder, occurs. The occurrenc...
متن کاملCharacterization of toxin from cheilanthes fern and its effect on lymphocyte proliferation and DNA fragmentation.
Thin layer chromatography of aqueous extract of whole Cheilanthesfarinosa fern indicated the presence of ptaquiloside or ptaquiloside like compound, coinciding Rf values with that of Pterosin B standard. HPLC analysis revealed the presence of 26.3 mg/kg ptaquiloside. In vitro studies of the aqueous extract on lymphocyte culture revealed a correlation between stimulative indices and concentratio...
