Resumen:
The profile of volatile compounds from the aerial parts of Eupatorium buniifolium was assessed bycapturing the aroma of fresh plants using three commercial SPME phases. These headspace solidphase microextraction procedures (HS-SPME) were coupled to GC-FID and GC-MS analysis.Hydrocarbon sesquiterpenes were the main components of E. buniifolium volatiles, followed byhydrocarbon monoterpenes. The three fiber performances were statistically comparable in theextraction of both terpene groups. E. buniifolium essential oil (EO) was obtained by steam distillation(SD) and assessed by both, direct injection and HS-SPME. The three fibers could reliablyadsorb/absorb the aromas of E. buniifolium EOs, with comparable with EO composition. Thefresh plant volatile profile significantly differed from its EO because some sesquiterpene fractionremained in the biomass after SD. Extracts of the fresh plant material were obtained using organicsolvents and evaluated by direct injection. Ethanol and ethyl acetate extracts gave a differentaroma profile of E. bunnifolium than the EO.
