Our research is based on the study of the physiological and morphological characteristics of two varieties of this plant, namely "Trapar" and "Zitna", under semi-arid conditions (Technical Institute of Field Crops in Sétif) during the 2022/2023 campaign.The morphological traits studied those that significantly influence the plant's adaptation and yield—include chlorophyll content, leaf area, number of siliques, silique diameter, and silique length. Results We found that the "Zitna" variety exhibited higher values compared to the "Trapar" variety. The results obtained showed that the "Zitna" variety had a better adaptation to the semi-arid conditions than the "Trapar" variety, and statistical analyses revealed a positive correlation between the studied variables, The climatic factor, particularly precipitation, can positively or negatively influence the diameter siliques, as plants subjected to water stress tend to reduce their silique diameter. Conclusion we can say that the "Zitna" variety adapted well to the semi-arid zone. Key words: Brassica napus L., water stress, Adaptation morph-physiologique, Zitna, Trapar.

L’objectif de la présente recherche est l’étude de composition chimique et les propriétés biologiques de la plante Hertia cheirifolia (L.) de la famille des Astéracées, qui est réputée par ses vertus thérapeutiques à travers l’évaluation de leurs effets anti-oxydant, insecticide et antibactérienne afin de mieux comprendre leurs potentiels thérapeutiques. La méthodologie implique l’extraction des composants de la plante par macération, donnant des extraits concentrés méthnolique et héxanique. Les polyphénoles ont été dosés à l’aide de la méthode de Folin-Ciocalteu et l’activité antioxydante a été évaluée à l’aide du test DPPH. Les tests d’activité insectcide del’huile essentielle et des extraits méthanolique et héxanique ont inclus des évaluation par contact et répulsion sur des adultes de Tribolium confusum , avec des applications directe pour mesurer la mortalité des insectes. Tandis que l’activité antibactérienne a été étudiée par la technique de diffusion sur disque pour une évaluation quantitative. Les résultats ont montrés un rendement d’extraction élevé de 41.38%,8.30 % pour l’extrait méthanolique et héxanique respectivement et un rendement moyen pour le l’huile essentielle (2.1g). Les extraits de Hertia cheirifolia se sont avérés riches en composés phénoliques avec un taux égale à 299.6176 GAE/mg. En ce qui concerne l’activité antioxydante , les extraits méthanolique et héxanique ont présentés des valeurs d’IC50 de 42.70mg/ml et 292.59 mg/ml respectivement soulignant un potentiel antioxydant consédirable. Pour l’activité insecticide, les tests ont montrés une faible mortalité chez les insectes exposés aux extraits et une moyenne mortalité au l’huile essentielle, démontrant ainsi une légère efficacité dans la lutte contre les insectes nuisibles.

Our work was devoted to the evaluation of some pharmacological activities (antioxidant and antibacterial) and the biochemical study of the ethanolic and hexane extracts of the leaves of the tree Salix purpurea L in order to manage the use of this plant . The maceration extraction showed a yield equal to 6.42% for the ethanolic extract and 5.34% for the hexane extract. The results of the quantitative analysis showed a richness of the leaves of this tree in active principles, in particular in total polyphenols (224.60mg/g ext dry). The evaluation of the antioxidant activity via the DPPH radical scavenger test revealed a very significant potential for the ethanolic extract with an IC50 equal to 0.08097 while the hexane extract shows an average potential (4.620). The study of bacterial potential of ethanolic and hexane extracts against E. coli, Staphylococus aureus, Pseudomonas aeruginosa, Streptococcus thermophiles, Fusarium, Oxysporumf.sp. lycopersici and Salmonella shows that both extracts have low activity against the six bacterial strains tested. Our results show that the leaves of this tree have very promising therapeutic properties that can be translated into biopharmaceuticals. Keywords: Salix Purpurea, Antioxidant activity, Bacterial activity, Phenolic compounds, Methanolic extract.

The present research work was to evaluate the biological activities and identify the chemical composition of the species Mentha suaveolens. This essence is an aromatic plant known for its medicinal properties and it belongs to the family of lamiaceae. The main objective was to better understand the compounds of this plant and to evaluate their antioxidant and antimicrobial activity, in order to better understand its therapeutic potential and its concrete applications. The extraction of the plant compounds was carried out by maceration, which resulted in concentrated extracts based on ethanol and hexane. The Folin-Ciocalteu method was used to measure polyphenols (Polyphenol Dosage). While the antioxidant activity was evaluated by the DPPH test. Finally, the antimicrobial activity was examined using the disk diffusion method, which allowed for a qualitative evaluation. The extracts of Mentha Suaveolens demonstrated a high richness in phenolic compounds, with high levels of total phenols. The ethanolic and hexane extracts showed IC50s of 0.47 mg/ml and 0.57 mg/ml, respectively, highlighting their considerable antioxidant potential. Furthermore, significant bacterial activity was observed in all bacterial strains tested, particularly against Pseudomonas aeurginosa. This impact is quite significant, with inhibition zones ranging from 8 to 24 mm. In summary, this study reinforces the interest of Mentha suaveolens extracts as promising therapeutic agents. Further studies are recommended to deepen the understanding of the active compounds, explore other extraction and activity assessment techniques, and conduct in vivo tests to verify their efficacy in real clinical conditions. These advances could promote the emergence of new natural treatments and a more efficient use of plant resources for health. Keys words : Mentha suaveolens, Antioxidant activity, antimicrobial activity, polyphenols.

Pallenis spinosa (L.) Cass. is a widespread plant in the Mediterranean region. Traditionally, it is used as a medicinal species to treat several ailments, from inflammation to skin injuries. Although the phytochemical content of this plant has already been investigated, there is currently limited data on Algerian P. spinosa. In this work, we focused on volatile compounds and non-volatile secondary metabolites extracted using HS-SPME and methanol from the aerial parts of P. spinosa collected from Northeast Algeria. Volatile constituents were analyzed by GC-MS, while non-volatile compounds were analyzed by NMR and HPLC-MSn. In total, 48 volatile compounds were identified, including sesquiterpene hydrocarbons (65.8%), monoterpene hydrocarbons (16.9%), and oxygenated monoter- penes and sesquiterpenes (8.3% and 6.5%, respectively). β-Chamigrene (16.2%), α-selinene (12.8%), β-pinene (10.6%), and β-caryophyllene (9.2%) were assessed as the main constituents. Concerning non-volatile metabolites, 23 polyphenols were identified (7.26 mg/g DW), and phenolic acids were predominant (5.83 mg/g DW). Tricaffeoylhexaric acid (1.76 mg/g DW), tetracaffeoylhexaric acid (1.41 mg/g DW), 3,5-dicaffeoylquinic acid (1.04 mg/g DW), caffeoyl dihexoside (0.35 mg/g DW), and chlorogenic acid (0.29 mg/g DW) were the most abundant ones. Several known flavonoids, such as tricin and patuletin glycosides, kaempferol, and apigenin, were also identified, and myricetin hexoside was detected in P. spinosa for the first time. Overall, our work is the first to report an ex- haustive characterization of volatile and non-volatile secondary metabolites from Algerian P. spinosa. The results represent a step forward in revealing the chemistry of this widespread plant species. Furthermore, they may contribute to rationalizing its traditional medicinal applications and preserve the biodiversity of Algerian flora.

Centaurea L. plants are used in phytotherapy and as food. C. tougourensis (CT) and C. dimorpha (CD) are endemic of Algeria and have been scarcely studied up to now. Here, the phenolic content of their aerial parts was investigated using validated methods. Furthermore, the antioxidant properties of CT and CD were evaluated by performing DPPH, ABTS, FRAP, and phenanthroline assays. CD showed the highest total phenol (219.8mg GAE/g) and total flavonoid (82.8mg QE/g extract) contents. CT showed the highest flavonol content (46.3mg QE/g). Chlorogenic acid, 4-OH-benzoic acid, and protocatechuic acid were the main compounds detected by LC-MS/MS. Several flavonoids were also detected in CD, while only hesperidin was detected in CT. Both the species showed antioxidant properties; however, radical scavenging activity and FRAP of CD were significantly higher than CT and were comparable with positive controls. Overall, this work affords a contribution to the characterisation and valorisation of the Algerian flora.

This study comprehensively analyzed the phytochemical profile, antioxidant activity, and enzyme-inhibitory properties of Rumex vesicarius (R. vesicarius) extracts using advanced food analytical methods. The methanol extract was profiled using high-performance liquid chromatography with diode array detector (HPLC–DAD), identifying 16 phenolic compounds, with cynarin (26.06 mg/g dry weight extract) as the most abundant compound, revealed for the first time in this species. The hexane extract was assessed by gas chromatography-mass spectrometry (GC–MS), revealing 12 compounds, predominantly linoleic acid (46.09%). Mineral content was measured using inductively coupled plasma mass spectrometry (ICP-MS), showing high concentrations of iron (497.03 mg/L) and calcium (3.31%). The methanol extract exhibited strong antioxidant activity, with IC 50 values of 47.25 µg/mL (DPPH assay) and 26.98 µg/mL (ABTS assay) and an A0.5 value of 33.76 µg/mL in the reducing power assay. The hexane extract exhibited significant enzyme-inhibitory activity against α-amylase (IC50=33.80 µg/mL) and α-glucosidase (IC50 = 154.19 µg/mL). Additionally, ADME/T (absorption, distribution, metabolism, excretion, and toxicity) analysis of the HPLC–DAD-detected compounds indicated favorable drug-likeness and pharmacokinetic properties. These findings underline the promise of R. vesicarius as a rich source of bioactive compounds with antioxidant and antidiabetic properties, making it a promising candidate for further research in functional foods. The use of robust analytical methods, including HPLC–DAD, GC–MS, and ICP-MS, ensures reliable and reproducible results, aligning with the standards of food analytical methodologies.

ABSTRACT This study biodiversity of the use of medicinal plants among the population of eastern Algeria for the treatment of irritable bowel syndrome (IBS), a prevalent gastrointestinal disorder. A total of 210 respondents, primarily women (63%), participated in the survey, revealing a significant inclination towards traditional remedies, particularly among individuals over 40;years old and those with no formal education (70%). The findings indicate that 70% of the participants reported using medicinal plants, with a notable preference for oral administration due to its patient-friendly nature and effectiveness in addressing internal disorders. The research highlights the predominant use of aerial parts of plants, with decoction being the most common preparation method, facilitating the extraction of active compounds. The study also emphasizes the socio-demographic profile of medicinal plant users, noting that married individuals constitute 70% of the respondents, reflecting their role as primary caregivers. The results suggest that the local population's reliance on traditional remedies stems from accumulated knowledge passed down through generations, although there is a concerning decline in this knowledge among younger individuals. The research also revealed the presence of 35 medicinal plants categorized into 21 families, with Apiaceae and Lamiaceae being the predominant ones. This research contributes to the understanding of the cultural significance and therapeutic potential of medicinal plants in Algeria, advocating for further clinical studies to validate their efficacy in treating IBS. By documenting local practices and preferences, this study aims to preserve traditional knowledge and promote the integration of herbal medicine into modern healthcare approaches, ultimately enhancing patient care and treatment options for IBS.

Actuellement, les plantes médicinales (PM) représentent une source considérable et permanente pour les principes actifs. Parmi les plantes médicinales industrialisées et commercialisées en Algérie, on trouve le Cuminum cyminum, Ocimum basilicum, Pimpinella anisum et Mentha pulegium. Parmi les mesures qui pourraient contribuer au redressement de ce secteur, nous citons l’instauration des surfaces cultivées des plantes médicinales. Ainsi, le semis, le bouturage et la culture in vitro qui pourraient être un moyen de production et d’approvisionnement en plantes médicinales. Ce travail expérimental sur la performance germinative des graines de C. cyminum, O. basilicum et P. anisum, dans le but de déterminer le taux de germination et la croissance dans 5semaines sans traitement dans la serre et avec traitement in vitro. Selon les espèces, les taux de germination presque sont homogènes dans les 2 compartiments de P. anisum et C. cyminum obtenu pour une durée de germination de 2 à 5 semaine tandis que l’O. basilicum a montré un retard dans la germination au cours de 3 premières semaines dans la serre, contrairement in vitro,ou il’a montré dès la 1ère semaine, et cela indique la nécessité de traiter les graines pour raccourcir le temps de germination. Ce travail expérimental aussi, a pour but la multiplication de M. pulegium par bouturage et culture in vitro, la culture in vitro donne des bons résultats concernant la multiplication de M. pulegium selon les paramètres de croissance (tige, racine, feuille et nœud) par rapport au bouturage.

Abstract The molecular polymorphism of the stock proteins, namely, glutenin and gliadin has been studied in order to perform a comparison of the genes coding for these factors in the quality of bread as much as they are major contributors to the elasticity and formation of wheat dough. DNA markers for quality traits are currently being used by wheat breeders to directly measure traits and performing biochemical tests. The aim of this study was to use DNA markers to search for varieties with glutenin genes (HMW and LMW) and gliadin genes also. 4 durum wheat varieties (alexandrium, murcenese, italicum and valencia) were used for these genes using PCR/RFLP markers via (F-56) and (R-56) primers. Results obtained show that polymorphism rate of this two primer is 54.54%. These two primers produce the same number of amplifiers whose size is 536bp. A total of eleven fragments are obtained for each primer. Five are relatively polymorphic, which concerns the genotype: 4, 20, 76, 91 and 92 through the pairing of an expression density materialized by low intensity bands. The study also revealed that there was no product at 527bp, the size of (HMW) glutenin gene; this indicates that the 100 genotypes do not contain this gene. Thus indicating its poverty in this element; compared to the (LMW) subunit of this gene which accounts for about 60% of glutenin proteins. While there is 770bp product for the gliadin gene, which indicates also that the 100 genotypes contain this gene. Thus indicating its good quality for bread making.
