ABSTRACT:With the exception of Dysphania ambrosioides, the Amaranthaceae has been relatively understudied in terms of volatile characterization of members of the family. The purpose of this work was to examine the essential oils of two species, Atriplex canescens and Grayia spinosa growing wild in southwestern Idaho. The essential oils were obtained by hydrodistillation and analyzed by gas chromatography (GC-MS and GC-FID). Essential oil yields were generally low (0.006-0.151% for A. canescens, 0.064-0.104% for G. spinosa). The major components in the essential oil of male A. canescens were 4-vinylguaiacol (16.8%), α-cadinol (13.1%), neo-intermedeol (6.9%), δ-cadinene (5.1%), α-elemol (4.7%), and bornyl acetate (4.6%). Female A. canescens, on the other hand, showed δ-cadinene (11.7%), epi-cubebol (6.8%), α-elemol (6.7%), 1-epi-cubenol (6.4%), cubenol (6.2%), cubebol (5.4%), and α-cadinol (5.2%) as major components. Grayia spinosa essential oils (all female) showed wide variation in compositions. However, green-leaf volatiles were generally abundant (10.5-37.5%) as was 4-vinylguaiacol (4.2-17.5%). Alkanes were abundant in one sample (33.1%), while dihydroedulans were abundant (14.5%) in another. There seems to be much variation in essential oil compositions both within species and between species of the Amaranthaceae.
