Current year’s growth was collected from ten plants found within an approximate 50 m radius of N32°40.605’ and W106°33.486’at an altitude of 1,741 m during July 2001. Composite samples of the plants were steam distilled in triplicate, and the composite oil was analyzed using both GC-FID and GC/MS. The volatile composition of the same plants was also examined using solid-phase microextraction (SPME) with a 100 µm polydimethylsiloxane fiber. Mass spectra and retention indices were used to identify 41 previously described compounds. Methyl salicylate (16.8%), hexanal (11.8%) and decanal (7.0%) were the major identified compounds.

The composition of dalea formosa oil determined by steam distillation and solid-phase microextraction / Mary E. Lucero in The journal of essential oil research, Vol. 17 N° 6 (Novembre-Décembre 2005) 

Public ISBD [article]  in The journal of essential oil research > Vol. 17 N° 6 (Novembre-Décembre 2005) . - pp. 645-647 Titre : The composition of dalea formosa oil determined by steam distillation and solid-phase microextraction Type de document : texte imprimé Auteurs : Mary E.

Sedillo, Auteur Année de publication : 2006 Article en page(s) : pp. 645-647 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Dalea  formosa  Fabacae  Feather  dalea  Essential  oil  composition  α-pinene Résumé : Dalea formosa Torr. (feather dalea, featherplume) was collected from the Jornada Experimental Range in south central New Mexico. Current year's growth was collected from 10 plants, all found within an approximate 50 m radius of the GPS coordinates N32°40.645′ and W106°33.601′ during July 2001. Composite samples of the plants were steam distilled in triplicate, and the composite oil was analyzed using both GC-FID and GC/MS. The volatile composition of plants collected from the same site was also examined using solid-phase microextraction (SPME) with a 100 μm polydimethylsiloxane fiber. Mass spectra and retention indices were used to identify 58 previously described compounds. The retention index and EI mass spectra are provided for one unknown. The most abundant constituents of the oil were α-pinene (31.7%), camphene (8.4%) and limonene (8.1%). In contrast, α-pinene (33.6%), β-pinene (13.2%) and camphene (11.1%) were the most abundant constituents of the SPME samples. This difference in composition may be due to either sampling technique or harvesting time.

Volatile composition of gutierrezia sarothrae (Broom Snakeweed) as determined by steam distillation and solid phase microextraction / Mary E. Lucero in The journal of essential oil research, Vol. 18 N° 2 (Mars-Avril 2006)

Compounds detected varied in quantity between isolation protocols. In the oil, cryptone (6.4%) and β-eudesmol (5.9%) were the only compounds comprising more than 5% of the chromatographic peak area. In samples prepared by solid-phase microextraction, limonene (10.4%), β-pinene (9.6%), β-eudesmol (8.0%), sabinene (7.8%), cryptone (6.5%), α-pinene (5.5%) and o-cymene (5.2%) accounted for 53% of the extracted volatiles. The results revealed a complex volatile composition from which unique compounds may still be identified.
