Due to the high prevalence of microorganisms resistant to conventional antimicrobials, the search for new antimicrobial drugs is underway, with nanoparticles being one of the options. This study reports for the first time the use of the coprecipitation method to synthesize europium (Eu) doped spinel manganese ferrites nanoparticles (MnEu 0.1 Fe 1.9...

Background In the search for a new and effective synthetic approach to biologically chromene-derived compounds, a series of 2-amino-7, 7-dimethyl-5-oxo-4H-tetrahydrochromene-3-carbonitrile derivatives (4a-i) were synthesized. This synthesis involved the use of 4-(dimethylamino)pyridiniump-toluenesulfonate (DPTS) as a catalyst in an aqueous medium....

Plants and their related phytochemicals play a key role in the treatment of bacterial and viral infections, which inspire scientists to design and develop more efficient drugs starting from the phytochemical active scaffold. This work aims to characterize the chemical compounds of Myrtus communis essential oil (EO) from Algeria and to evaluate its...

The use of medicinal plants is becoming more common as a result of their various therapeutic effects, which have been proven by sci�entific research aimed at discovering new substances that can be used as an alternative to synthetic molecules that have undesirable side effects, limiting their use in some cases. The objective of this review is to ex...

Objective: The use of preparations based on minerals extracts of Calicotome villosa and butter is born from the misuse of drugs without specific microbiological analyzes. Seventeen different preparations were performed. The antibacterial and antifungal activities were determined on five bacteria and two fungi strains respectively. Material and me...

This study is aimed at the extraction and chemical analysis of the essential oils of the leaves and flowers of Lavandula stoechas L growing in northeastern Algeria. The hydrodistilled oils isolated from leaves (0.75%) and flowers (0.6%) were characterized by fifty-two and sixtyfour compounds, respectively. Gas chromatography–mass spectrometry (GC-M...

The aim of this study is to determine the antibacterial effectiveness of leaves essential oil extracted from myrtle growing in Algeria. A cluster analysis of soil and water was effectuated for performing chemical and granulometric analyses. The essential oil was isolated from leaves by hydro distillation and analyzed by Gas Chromatography-Mass Spec...

Medicinal plants are a renewable source of natural bioactive compounds. The main objective is an attempt to partial recovery of three plants: Myrtus communis, Globularia alypum and Calicotme villosa by various treatments and uses components: essential oils, phenolic compounds and minerals. The determination of essential oils yield showed profitabil...

Globularia alypum leaves have been widely used for more years in gastrointestinal disorders as a traditional folk medicine. The aim of the present study was to determine the chemical composition of the petroleum ether extract and to evaluate its antioxidant activities in comparison with eugenol and its derivative isoeugenol. After phytochemical tes...
