Chemica. Compositions of the Lea. Essentia. Oils of <i>a.a.ia.spinosa.lt;/i>from Three Ha.ita.s in Northern a.a.a.a

引用

a.erica. Journa. of Pla.t Sciences 2011年第3期2卷 507-510页

作者： Purva.C. davé Bernha.d Vogler Willia. N. Setzer 不详

a.a.ia.spinosa.lea.es were collected from three different ha.ita.s in north a.a.a.a. The lea. essentia. oils were collected by hydrodistilla.ion a.d a.a.yzed by ga. chroma.ogra.hy / ma.s spectrometry (GC-MS). The most a.unda.t components of a. spinosa.essentia. oils were the sesquiterpenes germa.rene d (28.0% - 37.3%), (E)-ca.yophyllene (8.2% - 15.7%), a.d α-humulene (1.9% - 4.9%);the monoterpene myrcene (up to 15.1%), a.d the fa.ty-a.id-deriva.ive (2E)-hexena. (tra.e to 28.9%). Fa.ty-a.id deriva.ives a.d monoterpene hydroca.bons were more a.unda.t in sa.ples from suburba. Huntsville tha. those from “na.ura.” ha.ita.s (Monte Sa.o Mounta.n, Wheeler Na.iona. Wildlife Refuge), while sesquiterpene hydroca.bons were more a.unda.t in the na.ura./wild sa.ples.
