the essential oils of the fruits and fine stems of piper tuberculatum and of the roots of p. hispidum, collected in the state of rondˋnia, had been gotten by hydrodistillation and analyzed by gc and gc-ms. caryophyllene oxide - 32,1% in fruits and 26,6% in fine stem, and (e)-caryophyllene - 17,7% in fruits and 12,3% in fine stems, were identified as the major constituents in such parts of p. tuberculatum. in the essential oil of the roots of p. hispidum, dillapiol (57,5%), elemicine (24,5%) and apiole (10,2%) were identified as the most abundant constituents. from the ethanolic extract of the fruits of p. tuberculatum, the steroids 汕-sitosterol and stigmasterol, the amides piplartine and dihidropiplartine and the derivative of the cinamico acid 3,4,5-trimethoxy-dihidrocinamic acid were isolated.
