- aOrder of elution is given on apolar column (SPB-1)
- bRetention indices on SPB-1 column (RIa)
- cEssential oils of E. triquetrum stems. Quantification was carried out using RFs relative to tridecane as internal standard
- Abbreviations: %, normalized percentages are given on the apolar column; tr, trace (< 0.05%); RI: retention index; MS: mass spectrometry in electronic impact mode. All compounds were identified by comparing their EI-MS and retention indices with references compiled in the in-house library except for compounds 19 and 20; EO: essential oil. Yield is based on the fresh weight of the stems; Ref, Compounds identified with references from literature data and compiled in the in-house library
