Abstract	Bioactive compounds in wheat have received a great interest in the last few years due to their nutritional and health benefits. Various analytical procedures were used to identify these compounds in wheat kernels. An ultra‐performance liquid chromatography coupled to electrospray ionization quadrupole‐time‐of‐flight mass spectrometry (UPLC–ESI‐QTOF‐MS/MS) was used for the screening of bioactive compounds in seven Tunisian durum wheat extracts. The aim of this study was to realize a screening of several classes of bioactive compounds in the same analysis and to identify specific metabolite markers for discriminating the durum wheat varieties. The UPLC‐ESI‐QTOF‐MS/MS allows the detection of 81 metabolites, belonging to different chemical families such as sugars, organic acids, amino acids, fatty acids, and phenolic compounds represented by benzoic and cinnamic acid derivatives, phenolic alcohols, flavones, lignans, and condensed tannins. Chemical profiles identified varied greatly between different wheat genotypes. As far as the authors know, this is the first time that different chemical classes were detected at the same time in durum wheat kernels using UPLC‐ESI‐QTOF‐MS/MS. This study gives the most complete map of metabolites in Tunisian durum wheat and proves that UPLC‐QTOF‐MS/MS coupled with chemometric analysis is a great tool for discrimination between durum wheat cultivars.

Abstract	This study established physicochemical and sensory characteristics of virgin olive oils (VOOs) and linked them to consumers' liking using external preference mapping. We used five Tunisian and two foreign VOO varieties produced by two processing systems: discontinuous (sp) and continuous three-phase decanter (3p). The samples were analyzed and evaluated by a panel of 274 consumers. The external preference mapping revealed five VOO clusters with a consumer preference scores rating from 40% to 65%. Consumers highly appreciated the foreign Coratina cultivar's olive oil; the main drivers being richness in polyphenols (markers of bitterness and pungency), mainly the oleuropein aglycone, and volatile compounds (markers of green fruity, green leaves, green apple, cut grassy almond, and bitterness), particularly the

Abstract	Broomrapes are weedy root parasitic plants that cause important damage to the faba bean production. Genetic resistance is considered as the most desirable control method. In this study, we investigated some of the mechanisms involved in the resistance to Orobanche crenata and O. foetida for two Tunisian resistant varieties Najeh and Chourouk in comparison with the susceptible variety Badi. The results showed that, for Najeh and Chourouk, the Orobanche infestation did not significantly influence the plant growth as indicated by inconsiderable changes in the shoot and root dry weights, pod setting and chlorophyll and carotenoid contents. In comparison to Badi, both resistant varieties showed a reduced Orobanche attachments/tubercles number and dry weights, low H<sub>2</sub>O<sub>2</sub> and malondialdehyde (MDA) accumulation with increased levels of peroxidase activity in the roots. An Orobanche infestation was found to induce a significant decrease in the total lipid content and lipid unsaturation in the Badi leaves only. For resistant varieties, no significant changes were observed in these two parameters, which may indicate conservation and stability in the membrane fluidity. The resistance of Najeh and Chourouk was mainly associated with a relatively more efficient enzymatic antioxidative response and reduced lipid peroxidation that helped the plants to avoid the damaging effect of an Orobanche attack. Therefore, these two varieties could be used as a component of an integrated control strategy to improve the plant growth and productivity under an Orobanche infestation

Abstract	The olive plant has been extensively studied for its nutritional value, whereas its leaves have been specifically recognized as a processing by-product. Leaves are considered by-products of olive farming, representing a significant material arriving to the olive mill. They have been considered for centuries as an important herbal remedy in Mediterranean countries. Their beneficial properties are generally attributed to the presence of a range of phytochemicals such as secoiridoids, triterpenes, lignans, and flavonoids. With the aim to study the impact of geographical location on the phenolic compounds, Olea europaea leaves were handpicked from the Tunisian cultivar “Chemlali” from nine regions in the north, center, and south of Tunisia. The ground leaves were then extracted with methanol : water 80% (v/v) and analyzed by using high-performance liquid chromatography coupled to electrospray time of flight and ion trap mass spectrometry analyzers. A total of 38 compounds could be identified. Their contents showed significant variation among samples from different regions. Hierarchical cluster analysis was applied to highlight similarities in the phytochemical composition observed between the samples of different regions.

Abstract	Phenolic compounds are becoming increasingly popular because of their potential role in contributing to human health. Experimental evidence obtained from human and animal studies demonstrate that phenolic compounds from Olea europaea leaves have biological activities which may be important in the reduction in risk and severity of certain chronic diseases. Therefore, an accurate profiling of phenolics is a crucial issue. In this article, we present a review work on current treatment and analytical methods used to extract, identify, and/or quantify phenolic compounds in olive leaves.

Abstract	The aim of the current study was to assess the potential cardiopreventive effect of the methanolic extract of S. molle L. (MESM) on isoproterenol-induced infarction in rats. The biomolecules content was evaluated using HPLC–DAD-ESI-QTOF-MS/MS analysis. On the 29ᵗʰ and 30ᵗʰ days, two successive injections of isoproterenol (ISO) were given to Wistar rats to provoke myocardial infarction following pretreatment with either MESM (60 mg/kg b.w) or Pidogrel (Pid; 2 mg/kg b.w.). A total of sixteen phenolics were identified with masazino-flavanone as the most prevalent compound (1726.12 µg/g dm). Results showed that MESM offered cardioprevention by normalizing the ST segment and reducing the elevated cardiac risk parameters. The altered lipid biomarkers together with the plasma ionic levels were improved. Additionally, MESM inhibited the cardiac oxidative stress generated by ISO injection though enhancing antioxidant enzymes (GSH, CAT, SOD and GPX) which reduced lipid peroxidation and protein oxidation. MESM reduced myocardial apoptosis by significantly repressing mRNA expressions of Caspase-3 and Bax, with an upregulated Bcl-2 expression. Moreover, MESM reduced DNA fragmentation as well as the infarct size observed by TTC staining. In addition, MESM exhibited an antifibrotic effect by downregulating TGF-1β expression and reducing collagen deposition in myocardial tissue, as confirmed by Trichrom Masson analysis. The histopathological findings revealed less muscle separation and fewer inflammatory cells in the ISO + MESM-treated rats. Results of the docking simulation indicated that catechin in MESM was inhibitory mainly due to hydrogen bonding interactions with PDI, ACE and TGF-β1 proteins which could highlight the antithrombotic and antifibrotic capacity of MESM.
