In the present study, the chemical composition and the in vitro antimicrobial and antibiofilm activity of an ethanolic extract of propolis (EEP) from Tunisia against different ATCC and wild bacterial strains were evaluated. In situ antimicrobial activity and sensory influence of different EEP concentrations (0.5% and 1%), also in combination with 1% vinegar, were evaluated in chilled vacuum-packed salmon tartare.

Article Synopsis
  • The essential oil (EO) from myrtle, rich in compounds like myrtenyl acetate and linalool, was microencapsulated using maltodextrin through emulsification and spray-drying, achieving specific yield and efficiency rates.
  • The microencapsulated form, named MMEO, demonstrated significant gastroprotective effects in Wistar rats by reducing gastric lesions and acidity in an ethanol/HCl-induced ulcer model.
  • MMEO also showed strong anti-inflammatory properties, helping maintain antioxidant enzyme activity and suggesting that its protective effects stem from a combination of its anti-inflammatory and antioxidant actions.

In the frame of the sustainable use of neglected and underutilized phytogenetic resources, and along with numerous studies in spp. due to the innate conservation value of fir forests, this research focused on the Moroccan endemic fir, The aim was triple-fold: to assess its potential and dynamics in economic sectors for sustainable exploitation; to determine the ecological conditions in which the species naturally thrives; and to find the appropriate requirements for its successful seed germination. We sourced multifaceted evaluations for three economic sectors performed in three levels, using 48 attributes and eight criteria from previous studies of our own, and the relevant species-specific assessments are overviewed herein in detail.

Medicinal-aromatic plants (MAPs) are important sources for the development of new valuable products of interest to human and animal health, and are also used as ornamentals for the horticulture industry. However, the increased global demand and the uncontrolled exploitation of these plants constitute a threat to their sustainability. To date, few scientific investigations have focused on MAPs valorization and their domestication.

Article Synopsis
  • This research focused on analyzing the chemical compositions and biological effects of essential oils (EOs) from different needle types, finding significant variability in their profiles.
  • Key compounds identified include caryophyllene, phenyl isovalerate, β-myrcene, and α-pinene, with their specific concentrations measured.
  • Notably, the EO from Tabouba showed the highest antioxidant and anti-inflammatory activities, while Kettana's EO demonstrated strong cytotoxic effects against breast cancer cells, suggesting potential health benefits of these EOs as bioactive sources.

The neglected and underutilized plants (NUPs) could become alternative food sources in the agro-alimentary sector, enriching human and animal diets, offering the opportunity for sustainable exploitation, resilience to climate change, and production with resistance to pests and diseases. In the Mediterranean countries, these valuable resources are threatened by climate change, overexploitation, and/or monoculture. In this framework, we evaluated 399 local endemic NUPs of Crete (Greece), the Mediterranean coast, Rif of Morocco, and Tunisia, regarding their agro-alimentary potential, and assessed their feasibility and readiness timescale for sustainable exploitation with own previously published methodology.

(Aha) is an aromatic and medicinal plant rich in health-promoting flavonoids compounds that play an important role as antioxidant. For better utilization of this resource, the ultrasound-assisted extraction (UAE) of flavonoids and antiradical activities of obtained extracts from Aha using response surface methodology was assessed. A four-factor five-level central composite rotatable design was employed to discuss these extracting parameters: ethanol concentration (), temperature (), extraction time () and solvent to sample ratio ().

Aim: to study the quantitative and qualitative aspects of daily spontaneous nutrition as well as anthropometric characteristics and body composition of young Tunisian weightlifters.

Methods: Thirty one boys aged between 14 and 18 years, practicing for two hours a day, six days a week in the four weightlifting clubs in Tunis were invited to attend an evaluation session for a food survey (3 days recall, with consumption frequency over a period of 7 days) and the assessment of anthropometric measurements (Weight, height and skinfolds).

Results: Energy intake was acceptable.
