Besides a series of known sterols and triterpenoids, 2-methyl-5-(Z-non
adec-14-enyl)resorcinol and 5-(Z-nonadec-14-enyl)resorcinol have been
isolated from leaves of Ardisia silvestris. The last mentioned dipheno
l has also been obtained from roots of Ardisia gigantifolia. The struc
tures of these resorcinol derivatives were elucidated.
