Salicortin (1) and HCH-salicortin (2) were isolated and identified from the foliage of Populus fremontii and its F 1 hybrids with Populus angustifolia. Salicortin, but not HCH-salicortin, also occurred in P. angustifolia and complex backcrosses to angustifolia. Concentrations ranged from 0 to 17.5% dry weight for salicortin and 0 to 5.9% dry weight for HCH-salicortin. HCH-salicortin may possess potent anti-herbivore activity as it contains two of the hydroxycyclohexen-on-oyl moieties known to confer such activity to salicortin. Further, this compound may be a useful chemotaxonomic character within the genus Populus, since it appears to occur in section Aigeiros but not in section Tacamahaca.
