COMPOSITION OF THE VOLATILE OIL OF ALGERIAN ELAEOSELINUM FONTANESII AND THEIR PHYTOTOXIC ACTIVITY

The aim of the study is to evaluate the antigerminative effects of the essential oil from Elaeoselinum fontanesii Boiss. (Apiaceae) grow spontaneously in Algeria, against the germination and the radicle growth of seeds from cultivated plant Triticum durum Desf.
The volatile oil obtained by hydrodistillation from the aerial parts of E. fontanesii was analyzed by gas chromatography–mass spectrometry. 41 constituents were identified, representing 92% of the total oil, monoterpenes was the major chemical groups (75.9%) and high content of myrcene that was a characteristic compounds. The germination and radicle growth of seeds of durum wheat were controlled in different concentrations of the plant extract. The results showed high inhibition against the growth of radicale and the germination of the seeds.

Exploring and evaluating the phenolic profile and antioxidant properties of the Algerian wild carrot Daucus carota subsp. maximus aqueous extract.

Abstract
This study presents, for the first time, the phenolic profile of Daucus carota subsp. maximus aqueous extract and evaluates
its antioxidant properties using various in vitro assays. The aqueous extract contained significant polyphenol and
flavonoid contents (99.00 µg GAE/mg E and 43.06 µg QE/mg E, respectively). Additionally, LC-ESI-MS/MS analysis
made it possible to identify and quantify 19 phenolic compounds, with trans-ferulic acid as the predominant compound
(1.460 mg/g). Moreover, the aqueous extract exhibited antioxidant effects in all assays, with IC50 and A0.5 values less than
200 µg/mL except for Phenanthroline reducing power and SNP assays.
