The composition of essential oil isolated from Satureja thymbra, growing wild in Libya, was analyzed by GC and GC-MS. characterized γ-terpinene (39.23%), thymol (25.16%), p-cymene (7.17%) carvacrol (4.18%) as the major constituents. Antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method. It possessed strong antioxidant (IC50 = 0.0967 mg/mL). also screened for its antimicrobial against eight bacterial fungal species, showing excellent microorganisms...

The essential oils obtained by hydrodistillation from the aerial parts of Artemisia judaica L., herba-alba Asso. and arborescens L. (cultivated) Libya, were analyzed GC GC-MS. antimicrobial properties determined using broth microdilution method against eight bacterial species: Bacillus cereus (clinical isolate), Micrococcus flavus (ATCC10240), Listeria monocytogenes (NCTC7973), Staphylococcus aureus (ATCC6538), Escherichia coli (ATCC35210), Pseudomonas aeruginosa (ATCC27853), Salmonella...
The composition of essential oil isolated from Salvia fruticosa, wild growing in Libya, was analyzed by GC and GC-MS. Forty-five compounds could be identified. contained 1,8-cineole (49.34%), camphor (7.53%), ?-pinene (7.38%), myrcene (5.15%), ?-caryophyllene (4.13%) ?-terpineol (3.25). Antioxidant activity using the DPP H free radical scavenging method low antioxidant found (IC50 = 15.53 mg/ml). also screened for its antimicrobial against eight bacteria (four Gram-negative four...
Abstract The composition of essential oil isolated from Thymus algeriensis growing wild in Libya was analyzed by GC and GC-MS. characterized with thymol (38.50%) as the major component. screened for antioxidant activity using DPPH assay, compared to carvacrol. Antioxidant high, IC50 0.299 mg/ml, 0.403 0.105 mg/ml carvacrol, 0.0717 BHA. In addition, antimicrobial tested against eight bacteria fungi. T. showed inhibitory at 0.001–0.05 while bactericidal (MBC) achieved 0.0025–0.05 mg/ml. For...
We performed a comprehensive study of trichomes considering the medicinal importance essential oils produced in glandular Salvia aegyptiaca L. and lack data about leaf trichome characteristics. Micromorphological histochemical analyses S. were carried out using light scanning electron microscopy. report that leaves contained abundant non-glandular unbranched two types trichomes, peltate capitate, on both surfaces. The abaxial side was covered with numerous capitate while more adaxial side,...
Micromorphological and ultrastructural analyses of the leaf trichomes Salvia fruticosa Mill. were performed by light electron microscopy. The leaves bear numerous non-glandular unbranched trichomes, peltate, capitate digitiform glandular trichomes. Very elongated flagelliform densely covered surfaces, with especially abundance on margins. Peltate consist a basal epidermal cell, very short stalk cell large round head eight secretory cells arranged in circle. Capitate can be divided into two...
The endemic species Nepeta cyrenaica Quézel & Zaffran, native to northeastern Libya, is valued as an important honey-bearing plant.This study was aimed examine the micromorphology, phytochemistry, and bioactivity of in vitro-propagated N. for first time.The leaf indumentum examined using light scanning electron microscopy further characterised histochemistry. chemical composition essential oil (EO) performed GC-MS analysis, while dichloromethane (DCM), methanol (ME), ethanol (ET), aqueous...
Background: Since its discovery in 1926, Newcastle Disease is still emerging many avian species worldwide causing severe economic losses due to high mortality. Aim: This article aims discuss the challenge of virulent (ND) poultry Libya, focusing on recent outbreaks investigated Alzintan, Alrayaina, Nalut, and Surman, cities located western region Libya. Methods: Clinical signs lesions were recorded, tissues, as well tracheal cloacal swabs, collected. RNA extraction was performed for...
Introduction: Coronavirus Disease 2019 (COVID-19) is an infectious respiratory disease caused by SARS-CoV-2. The was first broke out in Wuhan City, Hubei Province, China and subsequently spread to all countries considered WHO as a worldwide pandemic. This study aimed determine the epidemiology of SARS-CoV-2 presence UK variants Zintan city Libya taking some risk factors into account. Methods: In cross-sectional retrospective study, total 15486 nasopharyngeal swabs were collected from...
Nepeta cyrenaica Quézel & Zaffran (Lamiaceae), an endemic species of the Libyan flora, has been scarcely explored until now. Since are proven as pharmacologically active plants rich in iridoid monoterpenes, this study was aimed to quantify iridoids present different extracts vitro propagated N. cyrenaica. The seeds collected from their natural habitat were germinated. One node stem explant 5-week-old used for plant micropropagation. After several cycles, shoots harvested. extraction...
Nepeta cyrenaica Quézel & Zaffran (Lamiaceae), an endemic species of Libyan flora, is here characterized for the first time its phytochemical composition and biological activities. Phenolic composition, antioxidant enzyme inhibiting effects extracts, prepared from five-week-old in vitro propagated N. shoots, were evaluated. Extraction was performed using dichloromethane, methanol, 96% ethanol or hot distilled water. LC-MS analysis showed that methanol extract contained highest amount...
