Four p-coumaroylated sesquiterpenoids (1-4), including three new ones (1, 2, and 4), were isolated from the whole plants of Pilea cavaleriei. Their structures were established on the basis of comprehensive spectroscopic analysis and comparison with data
A new p-coumaroylated santalane-type sesquiterpenoid, 8-p-coumaroyl-α-santalene (1), a new p-coumaroylated oplopanane-type sesquiterpenoid, 8-β-p-coumaroyl-oplopanone (2), and three known p-coumaroylated humulene-type sesquiterpenoids (3-5) were isolated from the ethanol extract of the whole herbs
