The aim of this work was to determine (i) the antioxidant capacity of Thymus moroderi, Thymus piperella, Santolina chamaecyparissus, and Sideritis angustifolia essential oils (EOs) by means of four different antioxidant tests (the 2,2'-diphenyl-1-picrylhydrazyl radical scavenging method, the ferrous ion-chelating ability assay, the ferric reducing antioxidant power test, and the thiobarbituric acid reactive species test) and (ii) the antifungal activity against molds and yeast of these EOs by the agar dilution and the microdilution methods. T. piperella EO showed the lowest 50% inhibitory concentration by the 2,2'-diphenyl-1-picrylhydrazyl radical scavenging method (9.30 mg/ml) and by the thiobarbituric acid reactive species test (6.30 mg/ml) and the highest value by the ferric reducing antioxidant power test (2.64 Trolox equivalent antioxidant capacity), while S. chamaecyparissus showed the lowest 50% inhibitory concentration in the ferrous ion-chelating ability assay (3.94 mg/ml). All EOs had a substantial inhibitory effect on all assayed yeast strains. S. angustifolia EO had the lowest MICs (2.5 μl/ml) for the yeasts Saccharomyces cerevisiae, Debaryomyces hansenii, Rhodotorula mucilaginosa, and Pichia carsonii. As regards antifungal activity, S. angustifolia EO at high concentrations was the most effective EO in reducing the growth of Alternaria alternata, Penicillium chrysogenum, and Mucor racemosus, while S. chamaecyparissus was the best inhibitor of the molds Aspergillus flavus and Mucor circinelloides. The results obtained in this study suggest the possibility of using these essential oils as natural antioxidant food preservatives.

The interest in natural phenolic compounds has increased because of their attractive use especially as antioxidant and antimicrobial agents in foods. The large content in phenolic compounds of interest in Santolina chamaecyparissus L. (S. chamaecyparissus) makes this plant a target source that is worthy of note. In this work, new extraction technologies comprising ultrasound (UAE) and microwave (MAE) assisted extraction of the phenolic compounds in S. chamaecyparissus have been developed, optimized, and compared. Several extraction factors have been optimized based on a Box-Behnken design. Such optimized factors include the percentage of methanol in water (25–75%), the temperature (10–70 °C), the ultrasound amplitude (20–80%), the ultrasound cycle (0.2–1 s), the solvent pH (2–7) and the solvent-sample ratio (5/0.2–15/0.2 mL/g) with regard to UAE, while the percentage of methanol in water (50–100%), the temperature (50–100 °C), the pH (2–7) and the solvent-sample ratio (5/0.2–15/0.2 mL/g) were optimized for MAE. The solvent composition was the most influential parameter both on MAEs (64%) and UAEs (74%). The extraction optimum time was established as 15 min for MAE and 25 min for UAE. Five major phenolic compounds were detected and identified by Ultra-High-Performance Liquid Chromatography—Quadrupole Time of Flight—Mass Spectrometry (UHPLC-QToF-MS) in the extracts: chlorogenic acid, quercetin 3-O-galactoside, quercetin 3-O-glucoside, isoorientin, and cynarin. With the exception of chlorogenic acid, the other four compounds have been identified for the first time in S. chamaecyparissus. The findings have confirmed that MAE is a significantly more efficient extraction method than UAE to extract phenolic compounds from S. chamaecyparissus.

“…This is the first report of antibacterial activity of this species against S. saprophyticus. Most of the studies revealed that the essential oil of S. chamaecyparissus showed the highest antibacterial activity against different bacterial strains [18,49,50]. On the other hand, S. saprophyticus was resistant to the different concentrations of methanol plant extracts of A. judaica and F. carica L.…”

In traditional medicine, medicinal plants are often used to treat a wide range of infectious diseases in humans. Objective: The aim of this study was to identify the phytochemicals contained in thirteen parts of six Yemeni medicinal plants: Artemisia Judaica, Ficus carica L., Nerium oleander L., Olea europaea, Santolina chamaecyparissus L. and Withania somnifera and to investigate the antimicrobial activity of different concentrations of methanol extracts from the aerial part of the selected plants against S. saprophyticus, Salmonella and E. coli in vitro. Methods: Phytochemical screening was carried out using standard procedures and the antibacterial activity of different extracts of each plant was studied by agar well diffusion method. Results: Phytochemical analysis of the plant extracts revealed the presence of phenols, saponins, essential oils, flavonoids, steroids, tannins, cardiac glycosides and alkaloids. The occurrence of phytochemicals varied from plant to plant. Tannins and phenols were found in all samples, while all other test samples contained at least five of the phytochemicals tested. Almost all extracts were able to inhibit the growth of the bacterial strains, with the exception of the species S. saprophyticus, which was resistant to the methanolic extracts of A. judaica and F. carica L. However, the methanol extract (0.1 g/ml) of S. chamaecyparissus L. and O. europaea showed the largest zone of inhibition (35 mm and 20 mm, respectively) against S. saprophyticus. This is the first report on the antibacterial activity of S. chamaecyparissus L. species against S. saprophyticus. Conclusions: The present screening result shows that the methanol extract of the tested traditional Yemeni medicinal plants exhibits potent antibacterial activity, and the studied plants may represent a new source for the discovery of novel antibacterial compounds for the treatment of drug-resistant human pathogens.
