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.

The resistance mechanisms of bacteria and protozoans have evidenced the need of discover new compounds with potential pharmaceutical activity against pathogenic microorganisms. Medicinal plants have been for centuries a promising alternative as sources of new drugs. The objective of this work was to evaluate the chemical composition, antimicrobial and antileishmanial activities of Cinnamomum zeylanicum, Origanum vulgare, and Curcuma longa essential oils. Chemical analysis was performed by gas chromatography-mass spectrometry. Antimicrobial activity was performed by disk diffusion and minimum inhibitory concentration (MIC) test. Antileishmanial activity was performed against antipromastigote and intracellular amastigote of Leishmania amazonensis. Cytotoxic and nitrite production were realized in BALB/c peritoneal macrophages. The major compounds of the essential oils were cinnamic aldehyde (46.30%) in C. zeylanicum, cis-p-menth-2-en-1-ol (33.88%) and linalyl acetate (13.90%) in O. vulgare, and turmerone (55.43%) in C. longa. The MIC showed significant antimicrobial activity of C. longa essential oil against S. aureus (83.3 ± 14.43 µg/mL). Antipromastigote activity showed IC50 values >500 µg/mL to C. zeylanicum, 308.4 ± 1.402 µg/mL to O. vulgare, and 405.5 ± 1.119 µg/mL to C. longa essential oil. Activity against intracellular amastigote of L. amazonensis showed IC50 of 63.3 ± 1.369 µg/mL and cytotoxic was not observed, resulting in selectivity index higher than 15.79 to parasite. C. longa essential oil decreased nitrite production in peritoneal macrophages, but not in Leishmania-infected cells. The chemical composition of the three essential oils is directly associated to its potential biological action, as the antimicrobial activity. C. longa presented a potent antileishmanial activity against promastigote and intracellular amastigote of L. amazonensis, although this activity is not linked to nitric oxide, since C. longa essential oil inhibits its production.
