This study aimed to compare the influence of extraction methods on pharmaceutical and cosmetic properties medicinal aromatic plants (MAPs). For this purpose, dried plant materials were extracted using advanced (microwave (MAE), ultrasonic (UAE), homogenizer (HAE) assisted extractions) conventional techniques (maceration, percolation, decoction, infusion, Soxhlet). The tyrosinase, elastase, α-amylase, butyryl, acetylcholinesterase inhibition tested by L-3,4 dihydroxy-phenylalanine,...
Growing pressure from climate change and agricultural land use is destabilizing soil microbial community interactions. Yet little known about resistance adaptation to disturbances over time. This hampers our ability determine the recovery latency of interactions after disturbances, with fundamental implications for ecosystem functioning conservation measures. Here we examined response bacterial fungal networks in rhizosphere Haloxylon salicornicum (Moq.) Bunge ex Boiss. course resulting a...
Isoquercetin (ISQ) is reported to be a powerful antioxidant with extremely high bioavailability and structural stability compared aglycone quercetin. Despite this, it not well studied due the limited methods for its extraction. With growing interest in research analysis of ISQ-rich herbs, there need optimize an efficient rapid method their In present study, ultrasound-assisted extraction ISQ from Ephedra alata Decne was optimized by response surface methodology (RSM) using high-performance...
Naringenin (NA) is a natural flavonoid used in the formulation of wide range pharmaceutical, fragrance, and cosmetic products. In this research, NA was extracted from Searsia tripartita using an environmentally friendly, high efficiency extraction method: ultrasound-assisted with deep eutectic solvents (UAE-DES).Six solvent systems were tested. Choline chloride as hydrogen bond acceptor (HBA), formic acid, ethylene glycol, lactic urea, glycerol, citric acid donors (HBD).Based on results...
ABSTRACT Significant spatial variability in NH 4 + , NO 3 − and H net fluxes was measured roots of young seedlings Douglas‐fir ( Pseudotsuga menziesii ) lodgepole pine Pinus contorta with ion‐selective microelectrodes. Seedlings were grown or no nitrogen (N), solutions containing one both N ions, a full factorial design. Net uptake efflux greater than not exposed to pretreatment. In general, the rates same presence absence vice versa . The highest influx occurred 0–30 mm from root apex 0–10...
The distribution of plant communities in hot desert ecosystems is discontinuous and resembles the pattern heterogeneous resource patches, known as "fertility islands". Understanding key factors that allow plants to establish these conditions, well their associated microbial diversity, crucial comprehension preservation ecosystems. Saudi Arabia Arabian Peninsula, one driest regions world, with a very low water regime soil nutrient contents. establishment arid conditions therefore subject...
Abstract Reforestation of degraded drylands calls for the selection species with capacity to withstand water scarcity. In this current study we have assessed, physiological responses three field-grown ( Ceratonia siliqua , Eucalyptus camaldulensis and Moringa oleifera ) deficits in semi-arid regions order suggest a potential rehabilitation programs. The behavior given was studied irrigation schemes: subsurface drip (applied weekly), tank monthly), unirrigated plants. stressed state, an...
Thymbra nabateorum, a plant species from the Lamiaceae family, is endemic to Nabatian region, which spans southern Jordan and northwestern Saudi Arabia. It renowned for its traditional uses rich phytochemical profile. This study aims examine composition of T. nabateorum evaluate biological activities, including antioxidant capacity, cytotoxic effects on cancer cell lines, enzyme inhibition relevant diabetes neurodegenerative diseases. The essential oil (EO) methanol extract were analyzed...
Soil microbiota plays a fundamental role in nutrient cycles and plant fitness. However, the response of bacterial fungal communities interacting with plants to an increase water regime natural ecosystems has yet be extensively studied. To address this matter, we studied rhizospheric root endophytic microbial simulated intense precipitation desert environment. We used amplicon sequencing identify (16S) (ITS) Haloxylon salicornicum (Moq) Bunge ex Boiss., pivotal species high potential for land...

Among these, symbiotic associations with mycorrhizal fungi nitrogen-fixing bacteria namely known to improve plant health, while providing resources benefit other microbial members. Yet, it is clear how these symbionts interact between each or they impact the microbiota network architecture. We used an extensive co-occurrence analysis, including...

Plant root traits are diverse and variable, the way in which they interact has consequences for fundamental functions such as anchorage, or services soil fixation. Here, we characterize mechanical related to anchorage (tensile strength, strain, stiffness toughness) at both intra‐ inter‐specific levels examine how covary with other economics space. We grew twelve herbaceous species from contrasting taxonomical families a common garden experiment. For each species, excavated systems measured...
Forests and woodland ecosystems in Morocco play a crucial role maintaining biodiversity providing ecological economic services. Despite advances administration, technology, research tools Morocco, these have received limited attention. This paper highlights the importance of forests focusing on their significance factors that pose threat to them. Furthermore, guidelines are provided for appropriate conservation measures future better understand current situation Morocco. The results show...
Abstract Main conclusion Emblematic Vachellia spp. naturally exposed to hyper-arid conditions, intensive grazing, and parasitism maintain a high nitrogen content functional mutualistic nitrogen-fixing symbioses. AlUla region in Saudi Arabia has rich history regarding mankind, local wildlife, fertility islands suitable for leguminous species, such as the emblematic desert trees. In this region, we investigated characteristics of legumes two nature reserves (Sharaan Madakhil), at one...
The equations used in soil physics to characterize the hydro-physical properties of medium cannot be other than empirical since they do not take into account multi-scale functional organization that is described Pedology. To allow researching correct formulation physical describing and properties, a new paradigm hydrostructural pedology being developed. This establish conceptual link between classical Pedology soil-water (hydrostructural characterization modeling medium). requires exclusive...
