“…This result is in agreement with those of Guan et al [21] and Nana et al [22] who obtained 11.5% and 10.54%, respectively. Although, these results are different from those acquired by several study [23][24][25][26][27] with a yield varying from 0.18 to 7.6%.…”

The aims of this study were to investigate the chemical composition, in-vitro antioxidant and antibacterial activities of Syzygium aromaticum essential oil. The essential oil was obtained by hydrodistillation. The GC-MS/GC-FID was used for determination of essential oil composition. The antioxidant activity was determined by DPPH radical scavenging assay and reducing power. The antimicrobial activity was evaluated by the broth microdilution method against six enteropathogens bacteria isolated from diarrhea of young calves. The results of the study revealed an average yield of the essential oil of 11.6% ± 0.97 (w/w). About 65 components were identified and quantified. Eugenol was the major compound of the studied essential oil (78.72%) followed by β-caryophyllene (8.82%) and eugenyl acetate (8.74%). The antioxidant activity by DPPH assay showed IC50 value of 4.82 ± 0.06 × 10 −2 µg/mL, while the reducing power assay have resulted an EC50 value of 3.47 ± 0.2 × 10 −2 µg/mL. The results showed that the essential oil exhibited an MIC at 1.36 mg/mL to 2.72 mg/ml and MBC at 5.45 mg/mL to 10.9 mg/mL against all tested bacteria. The present investigation revealed that Syzygium aromaticum essential oil exhibited a good in-vitro antioxidant and moderate in-vitro antibacterial activities.

“…The present study also showed that Clove oil was effective against all samples with inhibition zones ranging from 11-20 mm in agreement with many studies which considered oil of clove a substance with a strong antimicrobial activity (Rodríguez et al, 2014). In their study, eugenol was characterized as as an active antimicrobial agent.…”

Biofilm formation is becoming recognized as a key step in many infections. Prevention of this process as well as destruction of pre-formed biofilm are considered key strategies in controlling infectious diseases. The aim of the present work is to study biofilm formation in oral streptococci isolated from children aged 6-10 years and to test the antimicrobial and antibiofilm activity of four essential oils (Cinnamon, Clove, Eucalyptus, and Tea tree) by using three in vitro methods; Tissue Culture Plate, Tube Method, and Congo red agar for the detection of biofilm formation Results of this study showed that all oral streptococci exhibited biofilm formation with varying degrees. Also, cinnamon, clove, eucalyptus, followed by tea tree oil not only had a distinctive antibacterial activity against oral Streptococcal isolates, but also possessed anti-biofilm activity. These data provide evidence that plant oils could be potentially used as natural additives, clinically effective, inexpensive and safe plaque control supplements in the prevention of oral diseases.

“…The lethal oral dose of clove has been reported to be 3.752 g/Kg body weight [46]. Nowadays, the antimicrobial, anti-inflammatory, analgesic and antifungal activity of eugenol have made clove oil a promising natural alternative for the treatment of the oral cavity in dental medicine [48].…”

Plants and their extracts are the new field of interest for many scientists and also of some pharmaceutical industries. In order to provide more information for their usage in the prevention and treatment of diseases many clinical trials and researches are being carried out. In this review the biological activities and the mechanism of action of volatile phenylpropanoids (PPs) found in essential oils (EOs) are presented. The aim of this overview is to show that volatile PPs found in EOs can exert many of the biological activities which are generally attributed to EOs. Almost all of the PPs possess antimicrobial, anti-inflammatory and anticancer activities. These are related to the different substitution of the phenylpropane molecule. For each isolated group not only one, but more pharmacological activities can be credited.
