Date palm fruit development involves several stages, including Habauk, Kimri, Khalal, Rutab, and Tamer stages, characterized by intricate biochemical alterations that lead to the accumulation of various metabolites. The objective of this study was to quantify and statistically evaluate the linearity of nutritional compounds, acidity levels, water c...

Peptic ulcer disease remains a prevalent gastrointestinal disorder worldwide. Current treatments often have limitations, sparking interest in alternative therapies from medicinal plants. This review examines the gastroprotective potential of 54 North African medicinal plants against peptic ulcers. An extensive literature search was conducted, focus...

This study investigated the phytochemical composition and in vitro biological activities of leaf and seed extracts of Brassica oleracea var. elongata. Phytochemical screening revealed the presence of alkaloids, flavonoids, terpenoids, phenols, tannins, saponins, and reducing sugars in both methanolic and aqueous extracts. Quantitative analysis show...

This study focuses on the green synthesis of zinc oxide (ZnO) and magnesium-silver-doped zinc oxide (Mg-Ag-doped ZnO) nanoparticles (NPs) via biomass conversion of Algerian Ghars date palm (Phoenix dactylifera L.) seeds. Aqueous extracts of the seeds were utilized as reducing and stabilizing agents in the biogenic synthesis process. Structural, com...

This study presents an initial exploration of the phytochemical composition and biological properties of Salsola foetida, a wild plant native to southeastern Algeria. The investigation encompassed an analysis of the biochemical content, phytochemical profile, and bioactivity of the plant’s aerial parts. The biomass of S. foetida was found to compri...

This study extensively investigates the biochemical composition of male date palm leaflets (Phoenix dactylifera L.) from the El M'Ghair region in Algeria, focus-ing on the cultivars Deglet Nour, Degla Beida, and Ghars. The chemical analysis centers on proteins, total sugars, total phenols , and flavonoids, revealing significant differences in these...

he malignant tumor known as melanoma is generated from melanocytes in the epidermis basal layer1. The main forms of treatment for melanoma now accessible are surgery, radiation, systemic therapy, adjuvant therapy, photodynamic therapy, and transfer to therapy for mucosal melanoma2. Typical surgical treatments include biopsies, enlarged resections,...

Diabetes is a chronic disease that has affected millions of people worldwide. The current treatments for diabetes, such as insulin therapy and oral medications, have limitations, including adverse effects and high costs. Therefore, there is a need for new and effective treatments for diabetes. Recent studies have shown that plants from the Chenopod...

This work presents a comprehensive investigation of the biochemical composition of male date palm leaflets (Phoenix dactylifera L.) from the Biskra region in Algeria. The Biskra region experiences a subtropical hot desert climate with mild winters and extremely hot summers, featuring variable precipitation levels throughout the year. The study focu...

This study aimed to investigate the phytochemical composition and biological activity of Salsola tetragona Delile. (Amaranthaceae), a medicinal plant. The study evaluated the antioxidant potential of the crude extract and five fractions of S. tetragona using DPPH•, ABTS•+, CUPRAC, and metal chelating assays. The anti-inflammatory activity was deter...

The medicinal use of Salsola tetragona Delile (Amaranthaceae) aerial parts is a longstanding tradition. This study delved into the plant’s potential as an antioxidant, anti-diabetic, and anti-Alzheimer agent. The aerial portion extracted and evaluated four fractions (n-hexane, dichloromethane, ethyl acetate, n-butanol) for their antioxidant activit...

Phytochemicals, which are necessary for plants to adapt to their environment, offer an exciting source of medicinal products. This study focuses on the desert plant Anabasis oropediorum (Chenopodiaceae), which is native to calcareous sandy regions in North African countries and Palestine. This investigation is the first to shed light on the therape...

This study reports the biochemical profile and in vitro biological activities of the aerial part of two shrubs: Halocnemum strobilaceum and Suaeda fruticosa, a halophytes species native to saline habitats. The biomass was evaluated by determining its physiological properties and approximate composition. Hydro-methanolic extracts from Halocnemum str...

Current study verifies the biological efficiency of Bassia muricata (Chenopodiaceae vent), a wild plant in the Algerian desert. MeOH extract (70%) of the aerial parts of B. muricata was tested for antibacterial, anti-inflammatory and antioxidant activities. In addition to determining the value of the SPF and its effectiveness as hypoglycemia throug...
