Virus pretreatment with E. bicostata essential oil showed better antiviral activity (IC(50) = 0.7 mg/ml, SI = 22.8) than cell-pretreatment (IC(50) = 4.8 mg/ml, SI = 3.33). Elaissi A, Marzouki H, Medini H, Larbi Khouja M, Farhat F, Lynene F, Harzallah-Skhiri F, Chemli R. Chem Biodivers. Correlation between chemical composition and antibacterial activity of essential oils from fifteen Eucalyptus species growing in the Korbous and Jbel Abderrahman arboreta (North East Tunisia). 2019 Sep;134:103580. doi: 10.1016/j.micpath.2019.103580. The study was aimed to investigate the chemical composition and pharmacological basis for traditional use of essential oil of Nepeta cataria L. (Limiaceae) (Nc.Oil) in gastrointestinal and respiratory disorders. 2020 Aug 18;7:464. doi: 10.3389/fvets.2020.00464.

Essential oil from Nepeta cataria L. grown in Pakistan has not been explored yet for its chemical composition or its biological effects related to medicinal use in hyperactivity of gut and airways disorders. The yields of the 12 essential oils ranged from 2.23 wt.% in Curcuma yunnanensis to 4.50 wt.% in Curcuma longa.A total of 57 compounds were identified in the 12 essential oils. Silva JKRD, Figueiredo PLB, Byler KG, Setzer WN. Chemical composition of essential oil Essential oils (EOs) are volatile constituents obtained from aromatic plant material, including leaves, rhizomes, flowers, roots, bark, seeds, peel, fruits, wood and … 2007;21:374–377.

Tariq S, Wani S, Rasool W, Shafi K, Bhat MA, Prabhakar A, Shalla AH, Rather MA. E. odorata showed the strongest activity against S. aureus, H. influenzae, S. agalactiae, S. pyogenes, S. pneumoniae and against all the tested fungal strains. Essential oils were extracted from rhizomes of the 12 Curcuma species distributed in China by hydro-distillation, and their chemical compositions were isolated and characterized by GC–MS. In addition, DPPH assays indicated that these essential oils possessed different DPPH radical-scavenging activities (IC50, 3.69–30.19 μg/ml), some of them were better than Trolox C (IC50, 8.49 μg/ml).

This site needs JavaScript to work properly. Essential oil can be broken down into an array of different natural chemical constituents. These data indicate that Nepeta cataria possesses spasmolytic and myorelaxant activities mediated possibly through dual inhibition of calcium channels and PDE, which may explain its traditional use in colic, diarrhea, cough and asthma. In Tunisia, our previous works conducted in 2010 and 2011 had been the first reports to study the antibacterial activities against reference strains. Twenty five components were identified by GC/FID and GC/MS. Agence de Coopération Culturelle et Technique. A comprehensive review of the antibacterial, antifungal and antiviral potential of essential oils and their chemical constituents against drug-resistant microbial pathogens.

Reducing Ruminal Ammonia Production With Improvement in Feed Utilization Efficiency and Performance of Murrah Buffalo (. 2002;17:1–14. Get the latest public health information from CDC: NIH Variation in volatile leaf oils of 13 Eucalyptus species harvested from Souinet arboreta (Tunisia). These constituents include terpenoid and non‐terpenoid hydrocarbons and their oxygenated derivatives. This activity was dose-dependent and the antiviral activity diminished with the decreasing essential oil concentration. At that time it was not possible to evaluate their antimicrobial activities against clinical bacterial strains and other pathogens such as virus and fungi. The antioxidant activity of essential oil from Curcuma attenuata Wall (IC50, 3.69 μg/ml) was superior to all other oils. eCollection 2020. Abu-Jafar A, Suleiman M, Nesim N, Huleihel M. Cell Cycle. Conclusions: Some essential oils possessed much better antioxidant activity than Trolox C. PCA analysis and cluster analysis of essential oil compositions were useful for species classification. -, Cermelli C, Fabio A, Fabio G, Quaglio P.
