Phytochemical investigation of Idesia polycarpa (Salicaceae) resulted in the structure elucidation of nine previously undescribed phenolic natural products along with six known compounds. The compounds are structurally related to salicinoids that are known defense compounds from Salix and Populus species. The I. polycarpa diet was toxic, as shown in feeding experiments with larvae of Lymantria dispar,...
The leaves of Hasseltia floribunda were examined for their chemical constituents. Twelve phenolic glucosides, namely three hydroxycyclohexenyl acyl glucosides, four acylated salicortin derivatives, and five coumaroyl salicin derivatives, were isolated along with eight known phenolic glycosides, six known flavones, and two known sesquiterpenoid cyclohexenone derivatives. The structures of the isolated...
