Eucnide bartonioides yielded morroniside as the main iridoid constitue
nt. In addition, six minor iridoid glucosides were isolated namely the
known glucosides: kingiside, sweroside, secologanol, 8-epi-loganin an
d loganin as well as a novel iridoid glucoside, which Ly spectroscopic
methods was assigned to be 5-hydroxyloganin. The compound 8-epi-logan
in has so far been reported only from Scrophulariaceae and related fam
ilies and it is rather unexpected in Loasaceae. (C) 1997 Elsevier Scie
