Chemical Analyses, Antifungal and Insecticidal Properties of the Essential Oils of Eryngium Tricuspidatum L. (Apiaceae) Growing Natively in Tunisia

The present study investigated the interspecific variability of organic volatiles, the antifungal and insect repellency activities of the essential oils from two subspecies of Eryngium tricuspidatum; E. tricuspidatum subsp. tricuspidatum (E.t.S.t) and E. tricuspidatum subsp. bovei (E.t.S.b) (an Algerian-Tunisian endemic taxon) growing wild in Tunisia. The phytochemical characterization was carried out by using the hybrid analytical technique: gas chromatography paired with mass spectrometry (GC/MS), combined with gas chromatography-flame ionization detection (GC/FID). As a result, fifteen and nineteen compounds representing 80.3
