Chemical constituents analysis and antidiabetic activity validation of four fern species from Taiwan.
Chen CY, Chiu FY, Lin Y, Huang WJ, Hsieh PS, Hsu FL. Chen CY, et al. Int J Mol Sci. 2015 Jan 22;16(2):2497-516. doi: 10.3390/ijms16022497. Int J Mol Sci. 2015. PMID: 25622260 Free PMC article.
To address this question, the distribution of pterosins, glucose-uptake efficiency, and protective effects of pterosin A on beta-cells were examined. ...We also examined the distribution of these pterosin compounds in the mentioned fern species (except N …

Dissipation of pterosin B in acid soils - Tracking the fate of the bracken fern carcinogen ptaquiloside.
Skourti-Stathaki E, Clauson-Kaas F, Brandt KK, Rasmussen LH, Hansen HCB. Skourti-Stathaki E, et al. Chemosphere. 2016 Dec;165:453-459. doi: 10.1016/j.chemosphere.2016.09.050. Epub 2016 Sep 30. Chemosphere. 2016. PMID: 27677121
Pterosin B dissipation followed the sum of two-first order reactions. ...Our results demonstrate that pterosin B is microbially degraded and that pterosin B is as unstable as ptaquiloside and hence cannot be used as an indicator for former presence of ptaquil …

UPLC-MS/MS determination of ptaquiloside and pterosin B in preserved natural water.
Clauson-Kaas F, Hansen HC, Strobel BW. Clauson-Kaas F, et al. Anal Bioanal Chem. 2016 Nov;408(28):7981-7990. doi: 10.1007/s00216-016-9895-z. Epub 2016 Sep 2. Anal Bioanal Chem. 2016. PMID: 27590319
The naturally occurring carcinogen ptaquiloside and its degradation product pterosin B are found in water leaching from bracken stands. The objective of this work is to present a new sample preservation method and a fast UPLC-MS/MS method for quantification of ptaquiloside …

Carcinogenic effects of ptaquiloside in bracken fern and related compounds.
Potter DM, Baird MS. Potter DM, et al. Br J Cancer. 2000 Oct;83(7):914-20. doi: 10.1054/bjoc.2000.1368. Br J Cancer. 2000. PMID: 10970694 Free PMC article. Review.
Nineteen of 31 ferns tested by chemotaxonomic methods in Japan have been found to contain potentially carcinogenic ptaquilosides as have Cheilanthes sieberi and Pteridium esculentum. Hydrolysis of ptaquilosides leads to pterosins; under milder conditions a dienone which is …

Removal of phytotoxins in filter sand used for drinking water treatment.
Mrkajic NS, Hama JR, Strobel BW, Hansen HCB, Rasmussen LH, Pedersen AK, Christensen SCB, Hedegaard MJ. Mrkajic NS, et al. Water Res. 2021 Oct 15;205:117610. doi: 10.1016/j.watres.2021.117610. Epub 2021 Aug 27. Water Res. 2021. PMID: 34649082 Free PMC article.
All filter sands removed gramine and sparteine, primarily by a biological process, while jacobine N-oxide, senecionine N-oxide and caffeine were recalcitrant in the filter sands. ...In drinking water treatment systems biological sand filters might therefore remove p …

Presence of the carcinogen ptaquiloside in fern-based food products and traditional medicine: Four cases of human exposure.
Rasmussen LH. Rasmussen LH. Curr Res Food Sci. 2021 Aug 13;4:557-564. doi: 10.1016/j.crfs.2021.08.004. eCollection 2021. Curr Res Food Sci. 2021. PMID: 34458862 Free PMC article.
This study aimed to outline the presence of PTA in different human exposure routes by using and validating an LC-MS based protocol to test the contents of PTA in commercial products, the degradation product Pterosin B (PtB) and wild specimens from Europe, Asia and North Am …
