The investigation of the chemical composition, antioxidant and antimicrobial properties of the essential oil of Achillea collina Becker growing wild in western Romania was the aim of this study. The chemical composition of the essential oil was evaluated by GC-MS. The major compounds identified were chamazulene (38.89%), germacrene D (12.90%), beta-caryophyllene (11.52%) and beta-pinene (10.66%). The antimicrobial activity was assessed by the diffusimetric method against seven common food-related bacteria. No effects were observed against Clostridium perfringens and Streptococcus pyogenes. The antioxidant activity was evaluated using the DPPH test, the essential oil (IC50 = 25.03 ? 0.12 ?g/ml) demonstrated a stronger scavenging effect than BHA and lower than that of ascorbic acid and propyl gallate. The results reveal strong antimicrobial and antioxidant properties of the essential oil tested and contribute to future research to find new sources of natural antiseptics and antioxidants: a viable and safe alternative to reduce the use of synthetic additives.

The chemical composition of the essential oil obtained from the aerial parts of Santolina chamaecyparissus L., growing in Algeria, was investigated by GC-MS analyses. A total of 36 compounds were identified, accounting for 91.7% of the essential oil obtained. Camphor (31.1%) and cubenol (17.0%) were the predominant compounds. The potential of the antimicrobial activity was also investigated and the tested sample proved to be very active against Klebsiella pneumonia and Candida albicans (34.1 ± 0.02 mm and 35.0 ± 0.01 mm, respectively). Transverse sections of the leaf and stem of the plant suggest that the essential oil is localized in endogenous and exogenous sites.

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.

Abstract Chemical composition and antimicrobial activity of Teucrium capitatum L. subsp. lusitanicum essential oil was investigated for the first time in the present study. Qualitative and quantitative analyses of the chemical composition by gas chromatography and mass spectrometry (GC–FID and GC–MS) revealed the presence of 60 compounds representing 97.6% of the whole constituents. The main compounds were germacrene D (47.1%), spathulenol (5.8%), α-selinene (5.3%), germacrene A (2.9%), δ-cadinene (2.8%) and cubenol (2.7%). In vitro, the antimicrobial activity was investigated against five bacterial strains along with the yeast Candida albicans using broth microdilution assay. T. capitatum subsp. lusitanicum essential oil showed significant activity against the gram-positive bacteria Staphylococcus aureus (MIC = MBC = 78 μg mL−1), Bacillus subtilis (MIC = MBC = 156 μg mL−1) and the yeast C. albicans (MIC = MFC = 156 μg mL−1). The great potential of antimicrobial effects is most likely due to the very high percentage of sesquiterpene hydrocarbons particularly to germacrene D, for which the antimicrobial properties have been previously reported.
