对播娘蒿（Descurainia sophia（L.）从两个不同地点（沧州市-样品1和北京市-样品2）收集的Webb ex Prantl（狐尾草）在两种情况下分别以0.31%和0.26%的产率产生黄色油。通过GC和GC/MS分析了挥发油的详细化学成分，分别鉴定出40种和38种化合物。结果表明，样品1中含量最高的成分为顺式-β-罗勒烯（20.1%）、薄荷醇（11.27%）、乙酸新异薄荷酯（3.5%）、别香树烯（2.28%）和长环烯（2.25%）。与样品1相比，样品2中未检出1，8-桉叶素、α-桉叶醇、顺式、反式法尼醇和β-蒎烯等化合物，但顺式-β-罗勒烯（17.12%）、薄荷醇（10.7%）和乙酸新异薄荷酯（2.96%）等化合物在样品2中同样占优势。最终对两个样品精油中化学成分的分析表明，它们的化学成分相似，但样品2中所有共有化学成分的相对含量均低于样品1。
Exhaustive hydro-distillation of Descurainia sophia (L.) Webb ex Prantl (flixweed) collected from two different locations (Cangzhou city-Sample 1 and Beijing city-Sample 2) gave in both cases yellowish colored oils in 0.31 and 0.26% yield, respectively. Detailed chemical composition of the essential oils was analyzed by GC and GC/MS, and forty and thirty-eight compounds were identified. The results indicated that the most abundant component of Sample 1 were cis-β-ocimene (20.1%), menthol (11.27%), neoisomenthyl acetate (3.5%), alloaromadendrene (2.28%) and longicyclene (2.25%). Compared with the constituents of Sample 1, several chemical compounds such as 1,8-cineole, α-eudesmol, cis, trans-farnesol and β-pinene were not detected in Sample 2 although it was similarly dominated by cis-β-ocimene (17.12%), menthol (10.7%) and neoisomenthyl acetate (2.96%). Final analysis of the chemical constituents in the essential oils of the two samples showed similarity in their chemical composition, but the relative content of all shared chemical constituents in Sample 2 was lower than that in Sample 1.
