“…Importantly, we showed in the present study that Gram positive bacteria were more sensitive than Gram negative bacteria. These data are in line with previous published reports which demonstrated that gram (+) bacteria are more sensitive to plant extracts than gram (-) [26][27][28].…”

Objectives: The present study aims to determine the inhibitory effects of Rosmarinus officinalis essential oils (ROEO) on gastrointestinal transit in rats as well as the involvement of its antimicrobial properties in such protection. Methodology:The antibacterial power of the oils was evaluated against bacteria (2 Gram -bacteria, 2 Gram + bacteria) by the diffusion method on agar medium. The gastrointestinal transit (GIT) was assessed using charcoal meal method. In this respect, female Wistar rats were used and divided into six groups of eight each: control, ROEO treated groups. The last two groups were pretreated with clonidine and yohimbine, two reference molecules, which accelerate and delay TGI, respectively. Results:Our results demonstrated that the SOEO exhibited a broad spectrum of antibacterial activity, with a great effect against Gram+ strains compared to the Gram-. On the other hand, in vivo study showed that the ROEO significantly, and dose dependently, decreased the GIT activity. However, clonidine and yohimbine respectively decreased (39.76%) and increased (13.93%) the GIT. Conclusion:In conclusion, we suggest that ROEO had a potent inhibitory effect on gastrointestinal transit due in part to its antimicrobial properties.

“…For instance, EOs from various parts of Pinus halepensis cones [ 136 , 137 ], leaves [ 97 , 138 , 139 , 140 , 141 , 142 ], aerial parts [ 143 ], bark [ 137 , 141 ], seeds [ 137 ], and gum [ 144 ] have been repeatedly evaluated for their antibacterial, antifungal, or (less often) antiprotozoal, anthelmintic, and antiviral activities. EOs from various parts of many other Pinaceae species have also been evaluated for their antimicrobial effects, for instance, P. banksiana [ 44 ], P. brutia [ 145 , 146 ], P. cembra [ 39 , 79 ], P. densiflora [ 76 , 94 , 147 , 148 , 149 , 150 ], P. eldarica [ 127 , 151 ], P. halepensis [ 83 , 95 , 136 , 152 , 153 , 154 ], P. heldreichii [ 92 ], Pinus kesiya Royle ex Gordon (syn.

With a widespread distribution throughout the Northern Hemisphere and 11 genera, Pinaceae is the largest family of Gymnosperms in the world. Essential oils are an important chemotaxonomic marker for the species of this family, although the degree of chemical and biological investigation has not been the same for all genera. Essential oils from Abies and Cedrus (from the abietoid clade) or Pinus and Picea (from the pinoid clade) have been more extensively investigated with respect to their chemical composition and biological or pharmacological properties, including their antioxidant effects. Instead, essential oils from the other genera of the family have been less explored in this respect or even have not been investigated at all. This is a narrative review looking into the knowledge acquired up to date, the variability and limitations of the current methods used to estimate antioxidant effects, and multiple comparisons between EOs obtained from different genera, species, and plant parts, as well as potential applications and future directions of research and utilization of essential oils derived from Pinaceae species.

“…The value of the essential oils showed a better antioxidant activity when compared to ascorbic acid, used as reference antioxidant molecule. In another experiments, Selmi et al [13], Aloui et al [27], and Jedidi et al [28] assessed the antioxidant activities of essential oils obtained from aerial parts of Junepeus phoenicea, Pinus halepensis, and Rosmarinus officinalis, using 2, 2-diphenyl-1-picrylhydrazyl (DPPH • ) and 2,2′-azino-bis [3-ethylbenzthiazoline-6-sulphonic acid] (ABTS) tests. Essential oils of the four species exhibited strong antioxidant abilities to reduce the studied radicals.…”

Plants contain a considerable reservoir of secondary metabolites (flavonoids, tannins, and essential oils). These molecules exhibit variations in chemical structure as well as a very wide range of biological activities. Essential oils (EOs) are secondary metabolites produced by aromatic plants. EOs contain bioactive molecules, mainly represented by monoterpene hydrocarbons, oxygenated monoterpenes and sesquiterpenes, and sesquiterpene hydrocarbons. The organoleptic properties and biological activities of EOs are distinguished by their respective compositions. They have long been recognized for their medicinal properties such as antibacterial, antifungal, bioherbicide, antioxidant, anti-inflammatory, antidiabetic, and hepato-nephroprotective activities. These organic compounds also exert beneficial effects on the nutrition of ruminants, by modulating digestibility and reducing the emission of methane, a greenhouse gas. This chapter is devoted to the study of chemical composition, medicinal uses, and beneficial nutritional effects of essential oils.
