- Ceanothus gregii Gray was collected from the Jornada Experimental Range in south central New Mexico. 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.
