In recent years, medicinal and aromatic herbs, which contain variety of antimicrobial compounds and have no risk to human health in terms of antibiotic resistance, are increasingly used as alternatives to antibiotics. In the study, chemical composition, total phenolic content, antioxidant and antimicrobial activity of essential oil and extract of Mentha x piperita L. growing wild in Eskisehir were investigated. Carvone (55.8%), limonene (12.8%), 1.8-cineole (8.7%) and trans-dihydrocarvone (6.4%) were determined as the main constituents of the essential oil, while the major components of the extract were carvone (56.4%), 1.8-cineole (14.1%) and trans-dihydrocarvone (8.4%). The total phenolic contents of essential oil (2204.33 µg GAE/g) were significantly higher than of extract (744 µg GAE/g). The essential oil and the extract were inhibited 84.08% and 42.59% by the DPPH radical, 91.87% and 48.40% by the ABTS radical, respectively. The highest inhibition zone was observed against S. aureus (23 mm). However, minimum inhibition concentration (MIC) values of the essential oil were ranged between 2.5% and 10% (v/v), while MIC values of the extract were determined as 10% and >10% (v/v). The present study demonstrated that M. piperita could be used in pharmaceutical and food applications as a natural antioxidant and antimicrobial substance.

Tragopogon graminifolius DC., family Compositae, is widely consumed as a green vegetable in the west of Iran and for the treatment of gastrointestinal and hepatic ailments. In this study, the chemical composition of the essential oil from T. graminifolius aerial parts was evaluated by gas chromatography and gas chromatography mass spectrometry. Moreover, antioxidant and antimicrobial activity of the essential oil and various extracts of T. graminifolius were determined. Fifty-eight compounds representing 87.2% of the essential oil were identified. The main components were n-hexadecanoic acid (22.0%), β-caryophyllene (7.5%), heneicosane (6.6%), and nonanal (5.2%). The essential oil demonstrated the highest DPPH radical scavenging activity (56.6 ± 8.8ug/mL) and the 80% ethanolic extract the highest ferric reducing antioxidant activity (908.2±79.5 mmol Fe2+ ion/g extract). The total phenolic content of the 80% ethanolic extract from the aerial parts was the highest (560.7±18.8 mg/g gallic acid equivalent). In the antimicrobial test, Shigella dysenteriae was the most vulnerable microorganism, followed by Proteus vulgaris, and the essential oil exhibited the highest antibacterial activity among the samples. The results indicated that the essential oil and extracts of T. graminifolius could be consumed as a natural herbal preservative or complementary supplement in the food and pharmaceutical industries.

The essential oil obtained by hydrodistillation of the flowers of Rhanterium adpressum Coss. & Durieu was analyzed using GC and GC-MS. The essential oil was very rich in monoterpene compounds. The major components identified were the monoterpene hydrocarbons: camphene (21.8%), myrcene (19.3%) and α-pinene (17.4%). Other compounds, including limonene, β-pinene and terpinol-4-ol, were present in low content (4–6%). The composition of the fatty acids in the lipid extract obtained from the flowers was also investigated by GC and GC-MS. The main fatty acids identified were palmitic (47.4%), oleic (12.9%) and stearic acids (10.6%). The total phenolic contents and the antioxidant activities were also evaluated for both extracts. The total phenolic contents were determined using the Folin-Ciocalteu reagent and the antioxidant activities were measured using three different assays: DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging activity, FRAP (ferric reducing antioxidant potential) and a molybdenum assay. As a result of these tests, the lipid extract exhibited the highest antioxidant activities in comparison with the essential oil extract.

Abstract. Ziane L, Djellouli M, Berghioua A. 2021. Short Communication: Chemical composition, antioxidant and antimicrobial activity of Fagonia longispina (Zygophyllaceae) of Algerian. Biodiversitas 22: 3448-3453. The study's aim is to discover the antioxidant, antibacterial efficacy and identifying the main constituents of the essential oil of Fagonia longispina from southwest of Algeria. The essential oil from the aerial parts of the endemic plant Fagonia longispina collected from the region of Sahara southwest of Algeria was isolated by hydrodistillation and analyzed by gas chromatography-mass spectrometry.  Our work was designed then, to evaluate the antioxidant activity of the essential oil of Fagonia longispina by DPPH free radical scavenging and HPTLC techniques. Antibacterial potency of essential oil from this plant has been tested against Staphylococcus aureus (ATCC 29213), Escherichia coli (ATCC 25922), and Bacillus cereus (ATCC11778) by disk diffusion assay. We found that the chemical profile of the essential oil revealed the presence of 14 compounds: Trans–Pinocarveol (3.14 %), Panisaldehyd (4.24 %), Trans geraniol (3.05 %), carvacrol 18.72 %), Elemicin (22.85 %), (Z,E) Farnesol (15.69 %), Caryophyllene oxide (2.68 %), Alpha-curcumene (1.75 %), Germacrene D (4.22 %), longipinane (2.89 %) and ?-Terpinine (2.74 %). The antioxidant assay showed that the essential oil could scavenge DPPH (IC50 values of 2.1959 mg/mL free radical. The essential oil exhibits very effective antimicrobial activity using disk diffusion assay method with minimum inhibitory concentration ranging from 0.75 ?L/mL to 1.9714 ?L/mL. These results showed that this native plant may be a good candidate for further biological and pharmacological investigations.

This work aimed to evaluate the production of fresh and dry mass of leaves, stems and aerial parts, and the content and quality of lemon mint (Mentha x piperita var. citrata) essential oil as a result of four potassium (K) concentrations (276, 414, 552 and 690 mg.L-1) under hydroponic solutions. The experiment was carried out in the hydroponic NFT (Nutrient Film Technique) system. Leaves were separated and weighted to determine the fresh mass and part of them was used to extract oil in a Clevenger apparatus. The analysis of the oil chemical composition was performed in a gas chromatograph fitted with a mass spectrometer. The estimated concentration for the maximum fresh mass production of the leaves corresponded to 384 mg.L-1 K. The greatest K concentration proportionated an increase in essential oil content and yield per plant, but decreased linalool and linalyl acetate in the oil. Under the conditions the experiment was carried out, in order to obtain an adequate quantity of leaves for a higher essential oil yield per plant and linalool and linalyl acetate accumulus, the K concentration of 414 mg.L-1 is recommended in the hydroponic solution for the cultivation of lemon mint.
