从新墨西哥州中南部的Jornada实验范围收集了Psorothamnus scoparius（扫帚dalea）。本年度的增长收集了10种植物，都发现在大约50在半径的GPS坐标N32度41.286 '和W106度46.922'在2000年6月。混合样品进行水蒸气蒸馏，并使用气相色谱法与FID和GUMS分析精油。质谱和保留指数用于鉴定64个化合物。保留指数和EI质谱也提供了15个未知数。主要成分为γ-松油烯（22.3%）、对伞花烃（14.0%）和α-蒎烯（9.0%）。
Psorothamnus scoparius (broom dalea) 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 in radius of the GPS coordinates N32degrees41.286' and W106degrees46.922' during June, 2000. Composite samples were steam distilled, and the essential oil was analyzed using GC with FID and GUMS. Mass spectra and retention indices were used to identify 64 compounds. Retention indices and EI mass spectra are also provided for 15 unknowns. gamma-Terpinene (22.3%), p-cymene (14.0%) and alpha-pinene (9.0%) were the major constituents of the oil.
