Spirocyclopropane-type sesquiterpene hydrocarbons from Schinus terebinthifolius Raddi

Three sesquiterpene hydrocarbons with a spirocyclopropane skeleton (terebinthane) have been isolated from the fruits of Schinus terebinthifolius. Their structures were determined by a combination of mass spectrometry, and one- and two-dimensional NMR techniques.
