Compound 14 was also detected in B. tridentata. The synthetic compounds were characterized by one and two dimensional 1H and 13C NMR. The identification was obtained by coinjection of the oils with the synthetic standards and fragmentation pattern comparison.  aessential oils  aCompositae  aBaccharis myriocephala  aBaccharis platipoda  aBaccharis tridentata  aCadinols  aNovel cadinanes  aSesquiterpenes1 aFERRACINI, V.
