Abstract

The present work proposed an evaluation of the physiological performance, yield and chemical profile of the essential oil obtained from leaves and roots of Eryngium foetidum L. (Apiaceae) cultivated using different fertilizer sources. The other gas exchange and chlorophyll a fluorescence parameter was not different, suggested that the photosystem II was not affected by the different fertilizer sources. Highest essential oil yield was obtained in leaf samples cultivated with the mineral fertilizer (0.18%) and control conditions (0.22%), while it was obtained by mineral fertilization in the case of root samples (0.22%). The principal component analysis - PCA and hierarchical cluster analysis – HCA showed two groups: the first was formed by roots (OrgR, MinR and ConR), characterized by the constituents 2,3,4-Trimethylbenzaldehyde, Muurola-4,10(14)-dien-1β-ol, Isoshyobunone, para-Mint-1,5-dien-8-ol, 6-Canphenone, (E)-γ-Atlantone and (E)-β-Farnesene; and the second group formed by leaves (OrgF, MinF, ConF), related to (2E)-2-Dodecenal, t-2-Tetradecenal, 1-Dodecanal, 1-Decanal, Tetradecanal, γ-Terpinene, Mesitylene and ρ-Cymene.

摘要

目前的工作提出了对从Eryngium foetidum 的叶子和根中提取的精油的生理性能、产量和化学特征的评估L.（伞形科）使用不同的肥料来源栽培。其他气体交换和叶绿素a荧光参数没有差异，表明光系统II不受不同肥料来源的影响。在使用矿物肥料 (0.18%) 和对照条件 (0.22%) 培养的叶样品中获得最高的精油产量，而在根样品 (0.22%) 的情况下通过矿物施肥获得最高精油产量。主成分分析 - PCA 和层次聚类分析 - HCA 显示两组：第一组由根（OrgR、MinR 和 ConR）形成，其特征在于成分 2,3,4-三甲基苯甲醛、Muurola-4,10(14) -dien-1β-ol, Isoshyobone, para-Mint-1,5-dien-8-ol, 6-Canphenone, ( E )-γ-Atlantone 和 ( E)-β-法呢烯；并通过叶（OrgF，MINF，CONF），与（2形成的第二组ë）-2-十二碳烯醛，吨-2- Tetradecenal，1-十二醛，1-癸醛，十四烷，γ萜品烯，均三甲苯和ρ -伞形花序。
