An examination and study were carried out in order to investigate the beneficial advantages of Drimia maritima aqueous and hydroalcoholic extracts (DmAE/DmHE). The chemical profile was determined using rapid ultrahigh performance liquid chromatography–electrospray ionization tandem mass spectrometry analysis, revealing the presence of 31 bioactive...
Most of the species of the Teucrium genus are known for their strong anti-inflammatory and antioxidant activities due to their richness in phenolic compounds. Thus, one species of the Teucrium genus belonging to the Lamiaceae family named Teucrium pseudochamaepitys L. was chosen in this study. The main objective of this study was to establish the p...
The term of medicinal plants includes various types of plants used in herbalism and some of these plants have medicinal activity. Knowing that the Sahara represents the three quarters of the grounds of our country, and that it contains a vast practically unexplored flora. This fact tried us to study a plant which is in the Sahara pertaining to the...

Introduction:
The term of medicinal plants includes the plants that possess therapeutic properties or exert beneficial pharmacological effect on the human or animal. Knowing that the Sahara represents the three quarters of the grounds of our country, and that it contains a vast practically unexplored flora. This fact tempted us to study a plant whi...
The present investigation is aimed at screening the bioactive compounds present in the leaves of Pergularia tomentosa L. an important ethnomedicinal plant. The qualitative analysis for the present phytochemicals was performed using MeOH/H2O extracts. Phytochemical analysis showed the existence of some primary and secondary metabolites, phenolic, fl...
This study was aimed to assess in vitro antioxidant activity and to isolate some bioactive compounds present in the leaves and stems of Pergularia tomentosa L. The Phytochemical analysis of the leaves and stems extracts showed that this plant is rich of various secondary metabolites such as cardenolides, flavonoids, saponins, steroids, tannins, alk...
This study was aimed to extract and to isolate some bioactive compounds present in the stems of Pergularia tomentosa L. The Phytochemical analysis of the stems extracts showed that this plant is rich of various secondary metabolites such as alkaloids, flavonoids, saponins, steroids, tannins etc. Five extracts were obtained using different solvents...
In this study we used spectrophotometrical techniques to estimate antioxidant efficacy by using 2,2-diphenyl-1-picrylhydrazyl free radical scavenging capacity and reducing power capacity. We have used also electrochemical techniques performed by cyclic voltammetry. The present study examined the antioxidant activities of the methanolic extract (ME)...
For the first time in this report, we determined the antioxidative capacity of Cupressus sempervirens extracts by using two methods such as inhibition of superoxide anion (0∙−2) made by alkaline pyrogallol, and electrochemical generation of this radical. We have studied the O2/0∙−2 redox couple on the GC in DMF. We obtained well-resolved quasirever...
ABSTRACT
Phytochemical compounds are known to be components of many plants and herbs; they have received great interest from the public and scientists due to their health benefits as antioxidants. The aim of the present study was to reveal the bioactive compounds and evaluation of antioxidant activity of the ethyl acetate, n-butanol extracts of Ast...
A new megastigman sulfate (1) was isolated from the aerial part of Zygophyllum gaetulum. The structure of 1 was elucidated as (E)-3-sulfooxymegastigm-7-en-9-one by analysis of spectroscopic data. In addition, 22 known compounds were isolated. Triterpenoid saponins 3, 4, 5, 7, 9, 12, and 13, and compounds 17–23 were isolated from Z. gaetulum for the...
In order to explore the feasibility of suitable drying technology of tomato-paste, four solar drying methods were employed, namely (i) Basic Solar-drying Mode (SDM), (ii) Solar-Geothermal Drying (SGD), (iii) Convective Ventilated Solar Drying (CVD), and (iv) Combination of Ventilation and Geothermal Drying (VHD) and their effect on exergy efficienc...
The present work aimed to investigate and to determine some bioactive compounds present in the leaves of Algerian plant, Pergularia tomentosa L. The Phytochemical analysis of the leaves extracts showed that this plant is rich of various secondary metabolites such as alkaloids, flavonoids, saponins, steroids, tannins etc. Five extracts were obtained...

In this study, we will determined the total phenolic content (TPC) and the antioxidant activity of the methanolic extract (ME) of date palm (Phoenix dactylifera. L) fruits (DPF) of four native cultivars from Algeria: Ghars (Gh), Chtaya (Cht), DeglaBeïda (DB) and Tinissine (Tns). The TPC of ME of DPF was measured by using Folin-Ciocalteu. Thereafter...
The aim of this study is to investigate the antioxidant ability of the date fruits palm (Phoenix dactylifera L) of variety (Ali Ourached) which had been watered with different sources of water (Ground water and Tap water) from Oued Souf, Algeria. The methanolic extracts of Ali Ourached date fruit watering with Ground water (AG) and Tap water (AT) w...
Edible parts of two dates cultivars (Deguel ahmar and Tanslit) at four maturation stages khellal, besser, rutab and tamr were analyzed for
their phytochemical composition (total phenolic, total flavonoid and condensed tannins contents) as well as antioxidant and antibacterial
activities. The antioxidant activity evaluated in vitro using scavenging...
The objective of this research is to find a natural chemical compounds alternative available and free of side effects and high-impact effective against many bacterial strains. The crude methanol extracts of five date palm (Phoenix dactylifera L) fruits (DPF) were tested for antibacterial action against bacterial strains, the methanol extracts showe...
The main objective of this study is to find and determine the antioxidant and antibacterial activities of the phenolic extracts of the edible part for five date cultivars (Phoenix dactylifera L.) from Oued-Righ, namely, Ghars (Gh), Chtaya (Cht), Degla Beida (DB), Tinissine (Tns) and Tntbouchte (Tnb), and for this purpose we conducted tests of chemi...
In the present study, evaluation of antibacterial activity of Acetic Acid extracts of medicinal plant Limoniastrum guyonianum from Ouargla and El Oued regions (Algeria) against three bacteria strains: Staphylococcus aureus (ATCC 6538), Escherichia coli (ATCC 25922) and Pseudomonas aeruginosa (ATCC 9027) was done by using disc agar diffusion method....
Zygophyllum cornutum Coss. is an endemic plant growing in the northern Sahara of Algeria. It is used in traditional medicine against diabetes, hypertension and dermatitis.
