“…Plants belonging to Myrtaceae family like Pimenta racemosa have retained the attention of researchers, not only because of their high diversity and their distribution around the world, but also for their variable use in popular medicines to treat diseases [ 13 ]. In Benin, the leaves of this plant are used in culinary preparations where the species is known as “laurel leaf”.…”

The aim of this study was to evaluate the efficacy of the essential oil extracted from fresh leaves of Pimenta racemosa in the improvement of fermented fish flour producing technology. Essential oil of Pimenta racemosa was extracted by hydrodistillation and its chemical composition was determined by GC and GC/MS. Different types of fermented fish flours from Lesser African Threadfin (Galeoides decadactylus) were produced by the modification of the traditional processing technology and the introduction of a step of essential oil adjunction during the process. Three different essential oil concentrations (0.5, 1.0 and 2.0 μL g−1) were investigated. Physicochemical, microbiological and nutritional analyzes were performed in order to evaluate the quality of the fermented fish flour produced. Results obtained revealed that the essential oil of Pimenta racemosa investigated has a chemical composition characterized by the presence of myrcene (25.1%), chavicol (7.5%) and eugenol (51.1%). Fermented fish flour produced have a good nutritional potential. However, on the microbiological level, only samples produced by adjunction of essential oil have a low level of microbial contamination, with an absence of pathogenic microorganisms.

To ensure the safety of trypanocidal molecules of thiosemicarbazones hemi-synthesized in essential oil of Cymbopogon citratus, toxicology studies were conducted. These studies which were performed on rats "Wistar" had focused on our most active molecules: citral thiosemicarbazone, citral semicarbazone, citral 4phenylthiosemicarbazone and the starting substrate which was the essential oil of Cymbopogon citratus. From these studies, it appears that citral semicarbazone, citral 4-phenylthiosemicarbazone and essential oil were no toxic as LD 50 > 2000 mg/kg. Citral thiosemicarbazone was slightly more toxic with a LD 50 = 315 mg/kg. The study of biochemical parameters revealed that the use of a high dose of the compounds may affect kidney function. A strong dose of essential oil of Cymbopogon citratus could affect liver function. It appears that the citral 4-phenylthiosemicarbazone is a very promising compound because it had an excellent antitrypanosomal activity and had very low toxicity (IC 50 = 1.96 µM; LD 50 > 2000 mg/kg).

“…These compounds as reported by Loumouamou and co‐workes 38 showed antimicrobial properties. The chemical composition of leaves of Cymbopogon giganteus underlined a high percentage of cis ‐ p ‐mentha‐1,(7) 8‐dien‐2‐ol (19.4%), trans ‐ p ‐mentha‐2,8‐dien‐1‐ol (16.4%) and limonene (13.7%) and assumed that these compounds together with those present in minor quantity were responsible for the very interesting antimicrobial and bactericidal activities on both E coli and S aureus 39 . The Indian Cymbopogon martini studied before 40 revealed the highest sensitivity of its EO against S epidermis and E coli , due to its richness in p ‐menthadienols (more than 57% of identified fraction whose 14.4% was represented by p ‐mentha‐1, 7 8‐dien‐2‐ol).…”

Antibiotic resistance is considered by the World Health Organization (WHO) as one of the biggest public health challenges of our time. So, strengthening research and surveillance represents strategic objectives to overcome this problem. Plants keep on to awe us with their uncountable secondary metabolites which seem to be one of the greatest ways to cope with this problem. Phytochemicals, among those the essential oils (EOs), characterized several plant properties. 1 Several EOs evidenced antimicrobial activities 2 which made them suitable alternatives to synthetic antibiotics. 3 Juniperus sect. Juniperus L. includes evergreen dioecious shrubs or trees, 4 and it is divided into two subsections: a northern group with blue-black mature cones and one broad leaf stomatal band (J communis and allies; 2-4 spp.), and a southern group with orange-red mature cones and two narrow leaf stomatal bands separated by the midrib (J oxycedrus and allies; 5 spp.) (www.conif ers.org/cu/Junip erus.php; www.junip erus.org). The composition of the essential oils from leaves and berries of Juniperus species is well documented. 5-10 The medicinal use of Juniper turns back to 1550 BC, 11 and traditionally, they have anti-inflammatory, antifungal, antibacterial and antiseptic activities. 11-14 The Juniperus species are characterized by their high amount of EO specially accumulated in berries, wood, and
