Antileishmanial Activity of the Essential Oils from Three Trees Obtained in Different Phenological Stages.

Purpose: Leishmaniasis is a parasitic disease found in tropical areas, and it affects up to 12 million individuals globally. Chemotherapies now available include drawbacks such as toxicity, high cost, and parasite resistance. This work aimed to evaluate the antileishmanial properties of essential oils (EOs) extracted from aerial parts of Cupressus sempervirens (C.

Comparison of Different Extraction Methods for the Determination of Essential oils and Related Compounds from Coriander (Coriandrum sativum L.).

The volatile oil of coriander (Coriandrum sativum L.) obtained from the fruits by soxhlet-dynamic headspace (S-DHS), solvent extraction (SE), steam distillation (SD), hydrodistillation (HYD) and supercritical CO2 extraction (SC-CO2) were analyzed by GC-FID and GC-MS. The SC-CO2 offered a higher yield (4.

Salt effects on Origanum majorana fatty acid and essential oil composition.

Background: The effects of salt on the essential oil yield and fatty acid composition of aerial parts of two marjoram varieties were investigated. Plants with 6 leaves were treated with NaCl (75mM).

Results: Salt treatment led to a reduction in aerial part growth.

Essential oils and fatty acids composition of Tunisian and Indian cumin (Cuminum cyminum L.) seeds: a comparative study.

Background: Cumin (Cuminum cyminum L.) seeds of two geographic origins, Tunisia (TCS) and India (ICS), were studied regarding their fatty acid and essential oil composition.

Results: Oil yields were 17.

Water-deficit impact on fatty acid and essential oil composition and antioxidant activities of cumin (Cuminum cyminum L.) aerial parts.

This study is designed to examine the effect of water deficit on growth, fatty acid and essential oil composition, and antioxidant activities of Cuminum cyminum aerial part extracts. Plants were treated with different levels of water deficit: control (C), moderate water deficit (MWD), and severe water deficit (SWD). Plant growth (height, fresh and dry matter weights) as well as yield components were significantly increased under moderate water deficit and conversely reduced at severe level.

Fatty acids, essential oil, and phenolics modifications of black cumin fruit under NaCl stress conditions.

This research evaluated the effect of saline conditions on fruit yield, fatty acids, and essential oils compositions and phenolics content of black cumin (Nigella sativa). This plant is one of the most commonly found aromatics in the Mediterranean kitchen. Increasing NaCl levels to 60 mM decreased significantly the fruits yield by 58% and the total fatty acids amount by 35%.

Essential oils, phenolics, and antioxidant activities of different parts of cumin (Cuminum cyminum L.).

Cuminum cyminum L. roots, stems and leaves, and flowers were investigated for their essential oils, total phenolics, flavonoids, and tannins contents, individual phenolic compounds, and antioxidant activities. The essential oil was investigated by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS), whereas identification and quantification of individual target polyphenolic compounds was performed by reversed-phase high-performance liquid chromatography (RP-HPLC).
