Article abstract of DOI:10.1016/0031-9422(91)85073-9

A new illudane-type sesquiterpene glycoside, named dennstoside A, was isolated from Dennstaedtia scabra and characterized as an analogue of ptaquiloside, the carcinogenic principle of Pteridium aquilinium, on the basis of spectral analyses and chemical conversion to pterosin A.Key Word Index: Dennstaedtia scabra; Pteridaceae; illudane-type sesquiterpene glycoside; dennstoside A.
