The chemical composition, antibacterial and antioxidant activities of the essential oil obtained from Eryngium triquetrum from Algeria were studied. The chemical composition of sample oils from 25 locations was investigated using GC-FID and GC/MS. Twenty-four components representing always more than 87% were identified in essential oils from total aerial parts of plants, stems, flowers and roots. Falcarinol is highly dominant in the essential oil from the roots (95.5%). The relative abundance of falcarinol in the aerial parts correlates with the phenological stages of the plant. Aerial parts of E. triquetrum produce an essential oil dominated by falcarinol during the early flowering stage, and then there is a decrease in falcarinol and rebalancing of octanal during the flowering stage. To our knowledge, the present study is the first report of the chemical composition of E. triquetrum essential oil. Evaluation of the antibacterial activity by means of the paper disc diffusion method and minimum inhibitory concentration assays, showed a moderate efficiency of E. triquetrum essential oil. Using the DPPH method, the interesting antioxidant activity of E. triquetrum essential oil was established. These activities could be attributed to the dominance of falcarinol. The outcome of our literature search on the occurrence of falcarinol in essential oils suggests that E. triquetrum from Algeria could be considered as a possible source of natural falcarinol.

“…Hawas et al [ 80 ] isolated 11 flavonoid glycosides (including isorhamnetin 3-O-α-rhamnoside, isorhamnetin 3-O-β-galactoside, isorhamnetin 3-O-β-glucoside, isorhamnetin 3-O-β-rutinoside, myricetin 3-O-β-galactoside 4’-methylether, myricetin 3-O-β-glucoside 3’-methylether, myricetin 3-O-β-glucoside 4’-methylether, quercetin 3-O-β-glucoside, quercetin 3-O-β-glucuronide 4’-methylether, and rutoside) from the aerial parts of E. campestre . Then, most recently, Khalfallah et al [ 36 ] characterized five flavonoid derivatives from the aerial parts of E. triquetrum Vahl. described as kaempferol 3- O -β-D-glucoside, kaempferol 3- O -[6´´- O - E - p -coumaroyl]-β-D-glucopyranoside, kaempferol 3- O -[2´´,6´´-di-- O - E - p -coumaroyl]-β-D-glucoside, kaempferol 3- O -[α-L-rhamnosyl-(6 → 1)- O -β-D-glucoside, and quercetin 3- O -[α-L-rhamnosyl-(6 → 1)- O -β-D-glucoside].…”

“…Actually, some Eryngium species are also used as ornamental plants [ 31 ]. A mountain of scientific evidence has shown that different species of the genus Eryngium possess antimicrobial effects under in vitro and in vivo conditions [ 32 – 36 ]. Fig.…”
Medicinal and edible plants play a crucial role in the prevention and/or mitigation of different human diseases from ancient times to today. In folk medicine, there are different plants used for infectious disease treatment. During the past two decades, much attention has been paid to plants as novel alternative therapeutic agents for the treatment of infectious diseases due to their bioactive natural compounds such as phenol, flavonoids, tannins, etc. The genus Eryngium (Apiaceae) contains more than 250 flowering plant species, which are commonly used as edible and medicinal plants in different countries. In fact, some genus Eryngium species are used as spices and are cultivated throughout the world and others species are used for the treatment of hypertension, gastrointestinal problems, asthma, burns, fevers, diarrhea, malaria, etc. Phytochemical analysis has shown that genus Eryngium species are a rich source of flavonoids, tannins, saponins, and triterpenoids. Moreover, eryngial, one the most important and major compounds of genus Eryngium plant essential oil, possesses a significant antibacterial effect. Thus, the objective of this review is to critically review the scientific literature on the phytochemical composition and antibacterial effects of the genus Eryngium plants. In addition, we provide some information about traditional uses, cultivation, as well as phytochemistry.
“…However, the 3S configuration was suggested analogous with co-occurring compounds 1-5 on the basis of the positive [α] D value, which was also observed for this member of Eryngium polyacetlenes. trans-Epoxy-triquetrol (diastereomeric mixture 7a/7b) exhibited a sodiated molecular peak at m/z 299.1629 in the HRESIMS spectrum, consistent with the molecular formula C 17 H 24 O 3 , with a difference of 16 mass units with respect to panaxydiol (1) and triquetridiol (6). The NMR spectra (l " Tables 1 and 2) resembled those of the other co-occurring polyacetylenes, indicating the presence in the structure of the same terminal portions.…”
Phytochemical investigation of the ethyl acetate extract from the aerial parts of Vahl resulted in the isolation of new polyacetylenes, triquetridiol () and epoxy-triquetrol (/, diastereomeric mixture), and the lignan demethoxy carolignan Z (/, pair), together with a series of related known metabolites. Additionally, some already reported phenolic and flavonoid compounds were also identified in the extract. Structural elucidation of the new compounds was made by spectroscopic analysis, mainly NMR and mass spectrometry. To the best of our knowledge, this is the first report of polyacetylenes and lignans from.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
