Phytochemical Analysis and Antioxidant and Antifungal Activities of Powders, Methanol Extracts, and Essential Oils from L. and Desf. Benth.

Chemical residues in food pose health risks such as cancer and liver issues. This has driven the search for safer natural alternatives to synthetic fungicides and preservatives. The aim of this study was to characterize the chemical composition of the essential oils (EO), determine the polyphenolic contents, and evaluate the in vitro antioxidant and antifungal activities of methanol extracts (ME), essential oils (EO), and powders from L.

Essential oil of (L.) Lag. growing in Ksob River, Algeria.

The essential oil from the aerial parts of (L.) Lag. (Apiaceae), collected in Ksob River (Algeria) and obtained by hydrodistillation, was analysed by GC-MS.

Phytochemical analysis, antibacterial and antifungal effect of L. essential oil and methanol extract.

The aim of this study was to analyse the essential oil of from Algeria and to test the antioxidant and antimicrobial properties of this plant. The essential oil (EO) (57 constituents) included mainly α-pinene, β-pinene, nopinone, linalool, cryptone, and limonene. The plant polyphenolic contents and the antioxidant activity were determined.

Chemical constituents, anti-inflammatory, antioxidant and hemostatic activities of the -butanol extract of (Poir.) Rothm.

The phytochemical profile obtained from LC-ESI-MS/MS analysis of the -butanol extract (BEHL) from the North African endemic plant (Poir.) Rothm. brought about the identification of ten glycosylated derivatives of apigenin and luteolin flavones.

Essential oils from three Algerian medicinal plants (Artemisia campestris, Pulicaria arabica, and Saccocalyx satureioides) as new botanical insecticides?

Medicinal and aromatic plants represent an outstanding source of green active ingredients for a broad range of real-world applications. In the present study, we investigated the insecticidal potential of the essential oils obtained from three medicinal and aromatic plants of economic importance in Algeria, Artemisia campestris, Pulicaria arabica, and Saccocalyx satureioides. Gas chromatography coupled with mass spectrometry (GC-MS) was used to study the essential oil chemical compositions.

Chemical composition, antioxidant, anticholinesterase and antibacterial activities of Desf.

The study was performed on the dichloromethane (DCM), ethyl acetate (EAc) and -butanol (Bu) fractions (F) obtained from the 80% ethanol extract of Desf. aerial parts, collected in the North Eastern region of Algeria. Remarkable total phenolic and flavonoid contents were obtained, mainly for EAcF.

Chemical constituents and HRESI-MS analysis of an Algerian endemic plant - batt. - extracts and their antioxidant activity.

This is the first report on the phytochemistry and antioxidant activity of ethyl acetate and - butanol extracts from an Algerian endemic plant Batt. (Scrophulariaceae). Both extracts were subjected to a phytochemical study by semi-preparative HPLC, which led to the isolation and identification of nine compounds: methyl linolenate (1), methyl linoleate (2), Phytol-1(3), Martynoside (4), Isomartynoside (5), -martynoside (6), Ilwensisaponin C (7), Ilwensisaponin B (8), Ilwensisaponin A (9).

Coss. & Dur. (Asteraceae) extracts: New cyanogenic glucoside and other constituents.

The phytochemical investigation of both chloroform and ethyl acetate extracts of Coss. & Dur. led to the isolation of a new cyanogenic glucoside 6'-methacrylate prunasin () together with seven known compounds: hydroxy-11,13-dihydro onopordaldehyde , -sitosterol , daucosterol ), nepetin (), prunasin (), astragalin () and 7---D-glucopyranosyl centaureidin ().

Essential oil composition of aerial parts from Algerian Anacyclus monanthos subsp. cyrtolepidioides (Pomel) Humphries.

The chemical composition of the essential oil from the aerial parts of Anacyclus monanthos subsp. cyrtolepidioides (Pomel) Humphries (Asteraceae) growing in a semi-arid region of Algeria was investigated for the first time. The essential oil was obtained by hydrodistillation and fully characterized by gas chromatography-mass spectrometry (GC-MS).

An ethnobotanical survey of galactogenic plants of the Berhoum District (M'sila, Algeria).

Background/aim: This work aimed an ethnobatanical study on the galactogenic plants used in the Berhoum region (East of M'sila, Algeria) as a part of different studies on the medicinal plants related to M'sila region.

Methods: The fieldwork was undertaken as an ethnobotanical survey involving 76 informants (mean age: 50; 64% women, 36% men). Used the medicinal plants were identified, and the results were analyzed according to literature investigation dealing with ethnobotany.

Phenolic Profile and Antioxidant Activity of Centaurea choulettiana Pomel (Asteraceae) Extracts.

Aim And Objective: This study aimed to quantify phenolic compounds in ethyl acetate and n-butanol extract of Centaurea choulettiana Pomel (Asteraceae) leaves and flowers; compare the antioxidant activity of their extracts, identification and quantification of their phenolic acids.

Materials And Methods: Both organs extracts of Centaurea choulettiana Pomel were investigated and evaluated for their potential antioxidant properties using total phenolics and flavonoids content, DPPH radical scavenging and lipid peroxidation inhibition assays. HPLC-TOF/MS analyses were carried out to identify and quantify some phenolic acids.

Herbalists and wild medicinal plants in M'Sila (North Algeria): an ethnopharmacology survey.

Ethnopharmacological Relevance: The main aim of this study was to identify, catalogue and document the large number of wild medicinal plants used in the M'Sila region (northern Algeria) for the treatment of several human pathologies. Another more ambitious aim is to contribute to overcoming the limits of an orally transmitted pharmacopoeia, attempting to exploit the large ethnopharmacology patrimony of the region for further pharmacological purposes.

Materials And Methods: Our field study was carried out over a period of three years (2008-2010).
