Uf. Castillo et al., ISOPTAQUILOSIDE AND CAUDATOSIDE, ILLUDANE-TYPE SESQUITERPENE GLUCOSIDES FROM PTERIDIUM-AQUILINUM VAR CAUDATUM, Phytochemistry, 44(5), 1997, pp. 901-906
Ptaquiloside and two new illudane-type sesquiterpene glycosides were i
solated from Pteridium aquilinum var. caudatum. One- and two-dimension
al NMR analyses revealed the new glucosides to be isoptaquiloside and
caudatoside. Four pterosins, A, B, K and Z, were also isolated from a
base-acid treated extract. Copyright (C) 1997 Elsevier Science Ltd.
