Medicinal plants have been used since time immemorial to fight against diseases. The biological activities of these plants may be due to the presence of bioactive compounds such as essential oils. The aim of this study was to determine the chemical composition of three Yemen medicinal plants, and e evaluate their antibacterial and antioxidant activities. The chemical composition of essential oils was determined using gas chromatography–mass spectrometry (GC–MS) analysis. The antibacterial effect was evaluated against pathogenic bacterial strains using the micro-platoon method and the antioxidant activity was estimated by DPPH (2,2-diphenyl-1-picrylhydrazyl) scanning radical assay. Essential oils (EOs) are rich in phenolic compound. Carvotanacetone is the main compound of Pulicaria jaubertii (PJ) essential oil (82.35%) and β-maaliene (64.94%) is the major compound of Plectranthus montanus Benth (PMB) essential oil, while, Tarchonanthus camphoratus (TC) essential oil possesses several main compounds such as fenchol (14.5%), α-pinene (12.43%), and α-terpineol (8.58%). Essential oils of PJ and PMB showed remarkable antibacterial effect against Staphylococcus aureus (minimum inhibitory concentration, MIC = 0.25% [v/v]), and PJEO against Escherichia coli (MIC = 0.25%[v/v]); the lowestMBC (minimum bactericidal concentration) values was obtained with PJEO against Staphylococcus aureus (CMI = 0.25% [v/v]). TCEO interestingly showed capacity while scanning the DPPH radical (6.32 mg E Trolox). These findings showed the biological potential of Yemeni aromatic medicinal plants as antibacterial and antioxidant agents. However, further investigations are needed to determine the antibacterial and antioxidant mechanisms of these oils.

The main aim of this study is to determine the chemical compounds of Origanum compactum essential oils (OCEO) at three phenological stages (vegetative, flowering, and post-flowering) and to evaluate their antifungal activity against three dermatophytes fungal strains: Trichophyton violaceum, Trichophyton tonsurans, and Trichophyton mentagrophytes using direct contact method. The main compounds of OCEO are carvacrol, thymol, p-cymene, and γ-terpinene. Oregano EOs showed important antifungal activities with some variability between EOs and fungal testing. At a concentration of 0.75% (v/v), the best inhibition values showed with OCEO at vegetative stage against Trichophyton mentagrophytes (95.17%), Trichophyton tonsurans (92.47%), and Trichophyton violaceum (91.41%). The OCEO at vegetative stage also showed the best IC50 (concentration of an inhibitor where the response is reduced by half) values of 52.86, 0.56, and 0.57% (v/v) against Trichophyton mentagrophytes, Trichophyton tonsurans, and Trichophyton violaceum, respectively. The findings reveal that OCEO is a good source of anti-dermatophytes agents.

In the present work, we studied the potential antioxidant capacity and antibiofilm of pomegranate peel extract of two cultivars againstCandida albicansstrains. First, both pomegranate peel extracts were evaluated to determine their total phenolic and tannin contents. Their antioxidant activity was investigated using hydrogen peroxide scavenging assay. Acid fruit peel extract showed the most significant levels of total polyphenols (513.78 ± 1.552 mg GAE/g DE) and possessed the strongest antioxidant ability (96.32%). Next, the possible effect of the extracts onCandida albicansstrains was studied using agar diffusion method and subjected to various extracts concentrations. The zone sizes of growth inhibition showed clearly that these extracts had a good antifungal activity againstCandida albicansspecies in the following order: CA1 > CA3 > CA2 with minimum inhibitory concentrations (MICs) in the range 0.97–1.94 mg/ml. Images obtained by scanning electron microscopy allowed for a qualitative assessment of the biofilm reduction.

This study is aimed at describing, controlling, and improving the technological aptitude and the traditional pharmacopeia of Schinus terebinthifolius Raddi conventionally used by the local population of Tizi-Ouzou (northern Algeria) and justifying the possible industrial applications of the plant. The study involved the drying of Schinus terebinthifolius Raddi leaves using two types of drying process (hot air drying and open air drying). In addition, the evaluation of certain properties (physical and chemical, rheological and biological) of the obtained powders was carried out. Various gels were prepared using the powders of air-dried Schinus terebinthifolius Raddi leaves, DIC (instant controlled pressure-drop) swell-dried Ziziphus jujuba Mill fruits, and seed oil of the same fruit. These plants have been used traditionally for treating gastric disorders, wounds, and rheumatic pains. Schinus terebinthifolius Raddi is also used as an antiseptic and antihelmintic agent. The results of the analysis of Schinus terebinthifolius Raddi powders have shown important chemical constituents (Na, Mg, Fe, and K), bioactive substances (polyphenols, tannins, and fatty acids), and very interesting biological activities. The obtained gels confer better physical and chemical (slightly acidic gels) properties, a higher availability of phenolic compounds, and better rheological (viscous gel) and organoleptic properties than their chemical counterparts.

Sefrou city, located in the center of Morocco, is a focus of cutaneous leishmaniasis which constitutes a major public health problem. The majority of the rural local population resorts to herbal medicine to cure this parasitic disease. The aim of this study, which has never been undertaken in Sefrou area, was to document the list of medicinal plants used for treating cutaneous leishmaniasis and to verify if their leishmanicidal activity is mentioned in the literature. The current ethnopharmacological study was conducted using a questionnaire based on informations about anti-cutaneous eruption plants used by the local population and prescribed by the herbalists. The present work has taken into consideration the representation of the plant name (local and scientific), the used part, the mode of preparation and administration. A total of 17 plant species belonging to 12 families were mentioned: the Lamiaceae family was the most represented (29.4%) with 5 species, followed by the Myrtaceae family (11.8%) with 2 species. For the rest of the 10 families, they were represented with the same percent (5.9%) which means one species per family. According to the calculated frequency index (FI), the most recommended species were the following: Lavandula dentata (FI = 93.75%), Berberis hispanica (FI = 87.5%), Cistus salviifolius (IF = 87.5%), Crataegus oxyacantha (FI = 81.25%), and Ephedra altissima (FI = 75%). Leaves (29.4%) and flowers (23.5%) were the favored used parts. Decoction (58.82 %) was the most frequently used method to prepare remedies which are taken externally (64.7%). These medicinal plants can be a source of natural leishmanicidal drugs – some of them have already been confirmed experimentally in the bibliography. More indepth investigations must be undertaken to assess the antileishmanial potential of the inventoried plants.
