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.

Plant Latex

Plant latex is well-established as a defensive exudate against natural herbivory. However, its bioactive properties and potential use as a clinical adjunct are not fully explored in the current literature. In this study, latex was procured from Artocarpus heterophyllus Lam. (jackfruit) and subsequently evaluated for its antioxidant and antimicrobial activity. Aqueous extract (AE) and trifluoroethanol extract (TFE) of jackfruit latex were prepared using distilled water and trifluoroethanol. Both extracts were then characterized via thin-layer chromatography (TLC), ultraviolet-visible (UV-Vis) spectroscopy, and gas chromatography-mass spectrometry (GC-MS) analysis. Antimicrobial activity and antioxidant activity were determined for the extracts. Antibacterial activity was exhibited by TFE against P. aeruginosa, S. aureus, and Bacillus sp. The antioxidant activity of AE was significantly higher than TFE.

Antioxidant And Antimicrobial Activity

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.
