“…36 compounds were identified in OvEO, accounting for 89.87% of the total EO, the main chemical constituents are thymol (14.64%) and carvacrol (20.82%), which belonged to phenols. Thymol was the common component of TmEO, McEO and OvEO, this is consistent with the literature reported previous [ 18 , 19 , 20 ]. 34 compounds were identified in RoEO, accounting for 86.68% of the total EO, the main chemical components are eucalyptol (11.31%), verbenone (16.56%) and α-pinene (26.46%), monoterpenoid ketones and alkenes were dominated.…”

Using antibiotics as feed additives have been successively banned worldwide from 1986; therefore, it is an urgent task to finding safe and effective alternatives. As natural products of plant origin, essential oils (EOs) are an outstanding option due to their reported bioactivity. In this research, ten EOs of Labiatae species were extracted by steam distillation and its chemical constituents were identified by gas chromatography-mass spectrometry (GC-MS). A total of 123 chemical compounds, including alkenes, phenols, aldehydes and ketones, were identified. The results of antioxidant activity carried out through DPPH free radical scavenging (DPPH) and ferric reducing antioxidant power (FRAP), showing that EOs of Ocimum basilicum Linn. (ObEO), Thymus mongolicus Ronn. (TmEO), Origanum vulgare Linn. (OvEO) and Mosla chinensis Maxim. (McEO) have strong antioxidant activities. Their 50%-inhibitory concentration (IC50) value was <1.00, 1.42, 1.47 and 1.92 μg/mL, respectively; and their FRAP value was 1536.67 ± 24.22, 271.84 ± 4.93, 633.71 ± 13.14 and 480.66 ± 29.90, respectively. The results of filter paper diffusion showing that McEO, OvEO and TmEO inhibition zone diameter (IZD) are all over 30 mm. The results of two-fold dilution method showed that McEO, OvEO and TmEO have strong antibacterial activities against Staphylococcus aureus (S. aureus) and their minimal inhibitory concentrations (MIC) value was 1 μL/mL, 2 μL/mL, and 2 μL/mL, respectively. In conclusion, the results in this work demonstrate the possibility for development and application of EOs as potential feed additives.

“…Essential oils derived from oregano have valuable pharmacological properties that have been investigated by several groups [7]. Oregano is one of the most used aromatic plants as antimicrobial agent, whose essential oils are notably rich in phenolics mono-and sesquiterpenes [8]. The main chemotype of oregano species are carvacrol and tymol [9].…”

The compounds in Ginger (Zingiber officinale-Roscoe) essential oil provenience China and wild oregano (Origanum vulgare) essential oil of Romanian origin were identified by GC/MS and their antioxidant and antifungal properties were evaluated. Wild oregano oil was characterized by high content of oxygenated monoterpenes hydrocarbons (84.05%) of which carvacrol was the most abundant (73.85%) followed by b-linalool (3.46%) and thymol (2.29%). Ginger oil had a higher content of sesquiterpene hydrocarbons including zingiberene (31.47%), b-sesquiphellandrene (13.76%), a-curcumene (10.41%), a-farnesene (8.31%) and b-bisabolene (7.55%) but a lower content of oxygenated monoterpenes (7.97%). The high content of oxygenated monoterpens of wild oregano oil is in accordance with total content of polyphenols determined by the Folin�Ciocalteu method (6.71�0.73 mg of gallic acid equivalent per g oil). Ginger oil had only 1.34�0.22 mg gallic acid equivalent per g oil. Wild oregano oils exhibited appreciable in vitro antioxidant activity as assessed by 2, 2`-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and 2,2�-azino-bis (3 ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS). The sample concentration required to scavenge 50% of the DPPH free radicals was 0.76�0.13 mg/mL for wild oregano oil compared to 20.22�2.12 mg/mL for ginger oil. Also, wild oregano oils showed significant inhibitory activity against selected pathogenic fungi (Fusarium oxysporum, Aspergillus flavus and Penicillium expansum). 1�L of oregano oil is sufficient for almost 75% growth inhibition of Aspergillus flavus compared to ginger oil which shows antifungal activity at 240�L for 78% growth inhibition. It can be concluded that wild oregano oil could be used as food preservative in some food products in which Fusarium oxysporum, Aspergillus flavus and Penicillium expansum could grow and have potential to produce health hazards mycotoxines.

“…Thus, O. majorana is chemotypically different from the same species growing in other parts of Sicily (Tuttolomondo et al, 2013) and in other countries (Figuérédo et al, 2006;Sellami et al, 2009), which are characterized from different dominant constituents. Recently, EOs chemotypes have been defined on the basis of a single prominent monoterpene compound (La Pergola et al, 2017). However, they are often hard to compare when considering the whole monoterpene pattern, because of differences in composition according to the harvesting period, taxonomic classification, variety, age and part of the plant analyzed as well as geographical origin.…”

“…A recent study, also referred to caryophyllene anti-oxidant, anti-inflammatory, anti-cancerous and local anesthetic effects (Klauke et al, 2014). On the other hand, 4terpineol, abundant in O. majorana, has been reported as an important antifungal and antibacterial agent (Djeussi et al, 2013;Pezzani et al, 2017) while thymol and carvacrol are the most active constituents against multiple foodborne pathogens (La Pergola et al, 2017). However, the acetylated form seemed to have low toxicity and enhanced biological effects.…”

“…The presence of Origanum also occurs commonly throughout Asia, Europe, and northern Africa (Han et al, 2017). Members of this genus are extensively used in the flavoring and preservation of foodstuffs and alcoholic beverages (La Pergola et al, 2017). Similarly, rosemary is used worldwide for its antimicrobial and antioxidant activities, along with anti-inflammatory and anti-tumoral properties (Bajalan et al, 2017).…”

In this study, the antimicrobial activity of the essential oils (EOs) from Origanum majorana L. and Rosmarinus officinalis L. growing in Pantelleria (Sicily, Italy) were tested alone and in combination against some prokaryotic and eukaryotic food-borne pathogens. The chemical composition of the EOs as well as the minimum inhibitory concentrations (MIC) against the most sensitive strains were also determined. Both EOs showed interesting antimicrobial effects against all bacteria and yeasts tested. MIC was in the range 1.25–2.50 µl/ml. Interestingly, O. majorana was particularly rich in thymol acetate, while carvacrol was present at very low percentages. Also R. officinalis EOs composition was different from rosemary collected in different areas, as being particularly rich in caryophyllene. Furthermore, the antimicrobial activity of the combination of O. majorana and R. officinalis EOs indicated their potential as food biopreservatives.
