LC-ESI/MS-Phytochemical Profiling with Antioxidant, Antibacterial, Antifungal, Antiviral and In Silico Pharmacological Properties of Algerian (Cav.) Organic Extracts.

Cav. () is a medicinal plant with a long history of traditional use to treat ailments. In this study, total phenolic and flavonoid content evaluation using LC-ESI/MS analysis and various biological activities (antioxidant, antibacterial, antifungal, antiviral and cytotoxicity) of organic extracts from the aerial parts of were analyzed.

Comparison between Phenolic Content, Antioxidant, and Antibacterial Activity of Algerian and Turkish Propolis.

Background: Propolis is a natural resinous material produced by honeybees. The biological activity and phenolic profile of propolis were largely studied all over the world. However, only a few investigations have been carried out on Algerian and Turkish propolis.

Data on combination of parabolic solar system with CH cycle and power tower solar system with Cu-Cl cycle for hydrogen production in the city of Ghardaia (Algeria).

This data show the combination of parabolic through solar system with CH cycle and power tower solar system with Cu-Cl cycle for hydrogen production capacity in the city of Gharadaia which is located in the south of Algeria. A proper measurement of meteorological factors such as temperature, humidity, and solar irradiation has been done in the city of Ghardaia due to the solar concentration in this city. In the meantime thermo-chemical systems (Cu-Cl, CH4 cycles) have been integrated with the thermal solar systems through.

Data on safe hydrogen production from the solar photovoltaic solar panel through alkaline electrolyser under Algerian climate.

This data article is about hydrogen production from the solar photovoltaic solar panel through alkaline electrolyser under Algerian climate with the application of safe technology. Several pathways have been given different technologies for hydrogen production which were based on the experimental scale, where the catalysis of water by using alkaline electrolyser has taken the major part of the collecting data. However, in this data article, the photovoltaic solar system is integrated with a controller, an ammeter, a voltmeter, and an alkaline type water electrolyser (the electrolyte used is Na-OH).

Glucopyranosylbianthrones from the Algerian Asphodelus tenuifolius: Structural Insights and Biological Evaluation on Melanoma Cancer Cells.

Two new glucopyranosylbianthrones (1 and 2) were isolated from the aerial part of the plant Asphodelus tenuifolius, collected in Southwest Algeria. The 2D structures of 1 and 2 were defined by NMR analysis, HRESIMS data, and comparison with literature data. The comparison of experimental and calculated electronic circular dichroism and NMR data led to characterization of the ( M) and ( P) atropisomeric forms of the glucopyranosylbianthrones, asphodelins (1) and (2), respectively.

Effect of extract on TNFα, NF-κB and some tumor suppressor genes in breast cancer cell line Hs578T.

Background: The garden snail, , is a big land snail widely found in the Mediterranean countries. It is one of the most consumed species and widely used in zootherapy.

Objective: The present study was carried out to investigate for the first time the first time the antitumor activity of an aqueous extract from .

Analysis of pyrrolizidine alkaloids and evaluation of some biological activities of Algerian Senecio delphinifolius (Asteraceae).

Although Senecio species are known as sources of potentially toxic pyrrolizidine alkaloids (PAs), some species of this genus are traditionally used as remedies, notably in Algeria. In this paper, the evaluation of biological activities and the analysis of PAs of Algerian specimens of Senecio delphinifolius Vahl are reported. The n-butanolic extract of the herb showed a weak antibacterial effect against Escherichia coli with a MIC of 1 mg/mL, but was inactive against Staphylococcus aureus and Pseudomonas aeruginosa.

Influence of methylenetetrahydrofolate reductase C677T gene polymorphisms in Algerian infertile men with azoospermia or severe oligozoospermia.

Aims: The C677T allele of the methylenetetrahydrofolate reductase (MTHFR) gene has been suggested to represent a risk factor for male infertility. To confirm this association, the distribution of the single-nucleotide polymorphism C677T was investigated in idiopathic infertile Algerian patients with nonobstructive azoospermia (NOA) or severe oligoasthenoteratozoospermia (OAT). A case-control study was carried out, including 74 idiopathic infertile Algerian patients with NOA (n=46) or severe OAT (n=28) and 84 fertile men as controls.

Antioxidant compounds from Algerian Convolvulus tricolor (Convolvulaceae) seed husks.

Seed husk extracts of Convolvulus tricolor L. (Convolvulaceae) afforded six compounds, identified for the first time from this plant: isorhamnetin 3-O-beta-D-galactopyranoside (1), isorhamnetin 3-O-beta-D-(6"-acetyl)-galactopyranoside (2), isorhamnetin 3-O-robinobioside (3), 3,4-di-O-caffeoylquinic acid (4), gentisic acid 5-O-glucoside (5), and scopoletin (6). Separation of compounds was carried out by CC and CPC.

Chemical composition of the essential oil of Cachrys libanotis from Algeria.

The essential oil of aerial parts of Cachrys libanotis L. (Apiaceae) from east Algeria was extracted by hydrodistillation and analyzed by GC-FID and GC-MS. Thirty-one compounds were identified, the main components being germacrene-D (18.

Triterpenes from Euphorbia rigida.

Phytochemical studies of the aerial parts of Euphorbia rigida afforded three triterpenes: betulin (1), cycloart-23Z-ene-3, 25-diol (2) and cycloartan-3, 24, 25-triol (3), firstly isolated from this plant. The structures and relative stereochemistry were determined on the basis of extensive spectroscopic analyses, including 1D and 2D NMR experiments (1H NMR, 13C NMR, COSY, NOESY, HMQC and HMBC).
