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