This study investigates the pharmaceutical potential both in vitro and silico of ethanolic propolis extract from three Algerian regions namely TAH (Tahir-Jijel), ATH (Oued Athmania-Mila) OZ Zhor-skikda). Twenty-three compounds were identified via HPLC‒DAD, with key constituents including caffeic acid, cynarin, chrysin, naringin, hesperetin. Moreover, Antioxidant anti-Alzheimer activities assessed by multiple assays. Antimicrobial activity was tested against four pathogens one yeast. The...
Ammodaucus belongs to the family Apiaceae (Umbelliferae), subfamily Apioideae, trib Caucalideae, and comprises one species in Algeria (Quezel Santa, 1962). The biological importance of members this genus promoted us reinvestigate volatile constituents fruits leucotricus Coss. et Dur., carry out a study as far antibacterial activity is concerned. present work deals with chemical composition activities hydrodistilled oils. After extraction, oil was analyzed by gas chromatography–mass...
Abstract Background The biological importance of members genus Ferula promoted us to investigate the leaves vesceritensis Coss et Dur. (endemic plant) previously not investigated. This study presents chemical composition and antibacterial activities hydrodistilled oils. Results Volatile components F. have been studied by gas chromatography–mass spectrometry afford 23 compounds. major were found be 5,9-tetradecadiyne (24.72%), germacrene D (24.51%), farnesene (8.57%), α-bisabolene (8.57%)....
The investigation of propolis collected from Jijel, located in the northern-east part Algeria afforded five flavones: pectolinarigenin (1), pilosin (2), ladanein (3), Chrysin (4) and apigenin (5). structures were elucidated by spectroscopic analysis, including mass spectrometry, 1D 2D NMR.
Abstract The essential oils obtained by hydrodistillation from Daucus sahariensis Murb . harvested at three different growth stages were characterized GC/MS analysis. In total, 88 compounds identified, with myristicin (29.8–51.7%), myrcene (6.7–31.1%), α ‐pinene (11.6–14.8%), and limonene (5.3–11.5%) as main constituents. Monoterpene hydrocarbons the most represented in of plant samples collected during flower‐budding full‐flowering periods. On contrary, fruiting stage, dominated...
Several species of the genus Launaea are used in folk medicine such as bitter stomachic, skin diseases, and reported to have antitumor, insecticide, cytotoxic activities. The antimicrobial activities coumarin constituents neuropharmacological properties been investigated well. In this study, chemical composition essential oils from resedifolia L. has identified using ordinary GC-MS technique reveal presence 19 compounds dominated by dioctyl phthalate. Moreover, antibacterial activity crude...
This study aims to investigate the chemical composition, antioxidant, and antimicrobial activity of two essential oils (EOs) from Algerian propolis. The volatile constituents were analyzed by gas chromatography-mass spectrometry. Fifty components identified oils. major found be: cedrol (17.0%), β-eudesmol (7.7%), α-eudesmol (6.7%) in EO propolis Oum El Bouaghi (EOPO) whilst α-pinene (56.1%), cis-verbenol (6.0%), cyclohexene,3-acetoxy-4-(1-hydroxy-1-methylethyl)-1-methyl (4.4%) Batna (EOPB)....
Twenty compounds were detected in the essential oil of Rhanterium suaveolens representing 98.01% total content. Perillaldehyde (45.79%), caryophyllene oxide (24.82%) and β-cadinol (5.61%) identified as main constituents. In β-carotene-linoleic acid assay, both methanol extract exhibited good lipid peroxidation inhibition activity, with IC50 values 17.97 ± 5.40 11.55 3.39 μg/mL, respectively. DPPH CUPRAC assays, however, a antioxidant activity. The highest antibiofilm activity has been found...
In this study we investigated the chemical composition of roots Bunium incrassatum growing in Algeria; two coumarins, β-sitosterol, sucrose and oleic acid were isolated from methylene chloride:methanol (1/1) extract species. Furthermore, antimicrobial activity crude was evaluated using agar diffusion method. The results showed that had a great potential against all tested microorganisms especially fungal strains.
Phytochemical study of the aerial parts Foeniculum vulgare led to isolation seven compounds isolated for first time from this species.After and purification, these metabolites were characterized on basis spectroscopic analyses using 1D 2D NMR as well mass spectrometry.Furthermore, antimicrobial activity crude extract was evaluated agar diffusion method.The test results showed that had a great potential against all 9 microorganisms especially fungal strains.
The essential oils obtained by hydrodistillation from leaves and fruits of Daucus sahariensis Murb. were analyzed GC/MS. main constituents the oil myristicin (34.3%), alpha-pinene (5.4%), cis-chrysanthenyl acetate (5.3%) epi-alpha-bisabolol (4.8%), those (43.9%), (13.1%), limonene (9.4%), (7.4%). Myristicin, constituent both oils, is generally absent in other species, permitting hypothesis that this compound a chemical marker Saharan species.
Abstract Guava ( Psidium guajava L.) is a fruit tree largely used in folk medicine tropical and subtropical areas. This exotic species was introduced botanical garden the northeast of Algeria 1950’s. The aim this study to estimate, for first time, antioxidant anticholinesterase activities chloroform, ethyl acetate n-butanol extracts P. growing Algeria. Six assays were tested, results showed very important efficiency free radical scavenging, reducing power β-carotene bleaching tested...
Biometric measurements of leaves and fruits from Algerian atlas pistachio province Ouled Djellel (Biskra) Ain Oussara Messaad (Djelfa), were realized compared. The results showed significant differences between different varieties which may be due to climatic factors. Essential oils the oleoresin extracted examined then their antimicrobial activity was tested on five bacterial strains clinical origin (Staphylococcus aureus, Escherichia coli, coli ATCC 25922, Klebsiella pneumoniae,...
