The effects of salt stress on antioxidative activities were investigated in a coastal halophyte, Cakile maritima . Two Tunisian accessions, Jerba and Tabarka, compared. Plants subjected to 100, 200, or 400 m M NaCl for 20 days. Parameters oxidative [malondialdehyde (MDA), electrolyte leakage (EL), hydrogen peroxide (H 2 O ) concentration], several enzymes [superoxide dismutase (SOD), catalase (CAT), peroxydase (POD), ascorbate peroxidase (APX), monodehydroascorbate reductase (MDHAR),...
The neglected and underutilized plants (NUPs) have never been mainstreamed by researchers, politicians stakeholders for sustainable exploitation in the ornamental-horticultural sector. This study focused on 399 local endemic of three Mediterranean regions (Crete, coast-Rif Morocco, Tunisia), with aim to develop a new scheme their multifaceted evaluation facilitating exploitation. methodological was developed within multidisciplinary co-creative workshops experts adjusted end-users. uses...
Medicinal-aromatic plants (MAPs) are important sources for the development of new valuable products interest to human and animal health, also used as ornamentals horticulture industry. However, increased global demand uncontrolled exploitation these constitute a threat their sustainability. To date, few scientific investigations have focused on MAPs valorization domestication. The purpose this study was evaluate first time medicinal-cosmetic potential 399 local endemic Mediterranean confined...
The neglected and underutilized plants (NUPs) could become alternative food sources in the agro-alimentary sector, enriching human animal diets, offering opportunity for sustainable exploitation, resilience to climate change, production with resistance pests diseases. In Mediterranean countries, these valuable resources are threatened by overexploitation, and/or monoculture. this framework, we evaluated 399 local endemic NUPs of Crete (Greece), coast, Rif Morocco, Tunisia, regarding their...
The effects of salinity (0-400 mM NaCl, marked S0, S100, S200, and S400) on growth, photosynthesis, photosystem 2 (PS2) efficiency, ion relations, pigment contents were studied in two seashore Cakile maritima ecotypes (Tabarka Jerba, respectively, sampled from humid arid bioclimatic areas). Growth Jerba plants was improved at S100 as compared to S0. Tabarka growth inhibited by all NaCl concentrations. Leaf sodium chloride concentrations increased with medium higher than plants. Chlorophyll...
Abstract The effects of NaCl stress on the activity anti‐oxidant enzymes (superoxide dismutase, catalase (CAT), peroxidase (POD), ascorbate (APX), monodehydroascorbate reductase, dehydroascorbate reductase (DHAR), and glutathione (GR)), molecules (ascorbate glutathione), parameters oxidative (malondialdehyde (MDA), electrolyte leakage, H 2 O concentrations) were investigated in Cakile maritima , a halophyte frequent along Tunisian seashore. Seedlings grown presence salt (100, 200, 400 mmol/L...
The aim of this study was to investigate the antioxidant, anti-inflammatory, and anticancer properties two Tunisian Ephedra species (E. alata E. fragilis) through their phytochemical constituents. ethanol extract exhibited potent antioxidant power activities highpolyphenol contents. ethyl acetate possessedanticancer activity against cancerous cells MCF-7 (IC50 = 26 16 µg/mL in MTT resazurin tests, respectively) as well non Vero H9C2 143 22 using assay 49 12 test, respectively). Besides,...
L. essential oil (EO), mainly composed of myrtenyl acetate (30.6%), linalool (14.9%), α-pinene (11.10%) and 1,8-cineole or eucalyptol (9.9%), was microencapsulated with maltodextrin by emulsification spray-drying, reaching a yield efficiency 43.7 48.7%, respectively. The myrtle EO (MMEO) then evaluated regarding its gastroprotective activity in model ethanol/HCl-induced acute gastric ulcer Wistar rats. Pretreatment MMEO induced remarkable inhibition lesions acidity, correlated to high...
Frankenia pulverulenta L. (Frankeniaceae) is a medicinal species with carminative, analgesic and antiviral properties. However, phytochemical investigations, antioxidant neuroprotective capacities of this plant remain unclear.This work assesses the phenolic composition F. shoot root evaluates their capacities.Successive fractionation using 6 solvents were used. Antioxidant capacity these fractions was assessed through four in vitro tests (DPPH, ABTS, Fe-chelating activity ORAC). Phenolic...
In the frame of sustainable use neglected and underutilized phytogenetic resources, along with numerous studies in Abies spp. due to innate conservation value fir forests, this research focused on Moroccan endemic fir, marocana. The aim was triple-fold: assess its potential dynamics economic sectors for exploitation; determine ecological conditions which species naturally thrives; find appropriate requirements successful seed germination. We sourced multifaceted evaluations three performed...
In the frame of conservation and sustainable utilization neglected underutilized phytogenetic resources, this study produced for first time a detailed ecological profiling local Tunisian endemic Marrubium ascheronii (Lamiaceae) using Geographical Information Systems open-source data. This profile was used to illustrate abiotic environmental conditions its wild habitats; facilitated examination effect temperature on seed germination may inform species-specific guidelines cultivation in...
