“…These reported phenotypes were coherent with our findings. The positive strain Staphylococcus aureus has the lowest sensitivity toward the films' cloves oil components, especially eugenol, which is the main factor inhibiting fungal activity due of the lyses of spores and micelles [70,71].…”

Medicinal plants contain various secondary metabolites. The present study analyzed the essential oil of buds from clove (Syzygium aromaticum L.; Family: Myrtaceae) using gas chromatography-mass spectrometry (GC-MS). GC-MS analysis showed the presence of six major phytoconstituents, such as eugenol (66.01%), caryophyllene (19.88%), caryophyllene oxide (5.80%), phenol, 2-methoxy-4-(2-propenyl)-acetate (4.55%), and humulene (3.75%). The effect of clove essential oils (CEO) at 0%, 1%, 2%, and 3% (w/w) on the mechanical and barrier properties of starch films was evaluated. The tensile strength (TS) and elongation (E) of films with clove essential oil were 6.25 ± 0.03 MPa and 5.67% ± 0.08%, respectively. The antioxidant activity of the films significantly increased the millet starch film and presented the lowest antioxidant activity (0.3%) at a 30 minute incubation for the control sample, while increasing CEO fraction in the starch film lead to an increase in antioxidant activity, and the 3% CEO combined film presented the highest antioxidant activity (15.96%) at 90 min incubation. This finding could be explained by the incorporation of clove oil containing antioxidant properties that significantly increased with the incorporation of CEO (p < 0.05). A zone of inhibition ranging from 16 to 27 mm in diameter was obtained when using a concentration of CEO ranging from 1% to 3%. We also observed the presence of an antimicrobial activity on several tested microorganism including Escherichia coli, Pseudomonas aeruginosa, Enterobacter sp, Bacillus cereus, Staphylococcus aureus, and Trichoderma fungi. Thus, the current study reveals the possibility of using a millet starch edible film as a preservation method.

“…Studies have shown that clove essential oil is effective in reducing the microbial load of hatching eggshells, provides good results in terms of incubation performance, and improves the quality of neonate chicks [3,12]. This oil is an aromatic hydrophobic extract of Syzygium aromaticum (family: Myrtaceae) and is mainly composed of phenylpropanoids, such as eugenol (C 10 H 12 O 2 ), which constitutes 90% of the oil and is the main compound responsible for its antimicrobial activity [13,14].…”

The objective of this study was to evaluate whether sanitizing hatching eggs with clove essential oil in the preincubation phase affects broiler performance and influences the hatch window and quality of embryos and one-day-old chicks. Hatching eggs (n = 1280; mean weight = 58.64 ± 0.49 g) from a batch of 37-week-old broiler breeder hens of the CPK (Pesadão Vermelho) lineage were randomly distributed into four treatments in the preincubation phase. The treatments consisted of three different sanitization procedures (spraying with grain alcohol, spraying with clove essential oil, and fumigation with paraformaldehyde) and a control treatment (nonsanitized). The lengths of the embryos and one-day-old chicks (one of the parameters used to assess bird quality) were not significantly different among the treatments, with means of 15.30 ± 1.41 and 18.37 ± 0.76 mm, respectively. Body weight, body weight gain, feed consumption, and feed conversion rate in different rearing periods did not differ significantly among the treatments. However, there was a significant difference in the percentage of survivability during the initial period (1 to 28 days) among the treatments. In conclusion, clove essential oil treatment did not negatively affect the quality of embryos and one-day-old chicks or the performance of broilers.

“…The results of this study are in agreement with those obtained previously in cultivated cloves. Cultivated cloves produce the highest oil content in the flower part, which is around 10-20%, then followed by flower stalks around 5-10%, and the lowest is the leaves which is <5% (Nurdjannah, 2004;Widayat et al, 2014;Atanasova-Pancevska et al, 2017).…”

The cloves of Tuni and Zanzibar varieties from Ambon Island have morphological differences that affect the production and quality of the clove oil produced. This study aimed to evaluate the characteristics of the agromorphology and physicochemical properties of clove oil of the two varieties. The standard color determination was performed visually, specific gravity was using pycnometer, refractive index using a refractometer, and 70% ethanol solubility using silver nitrate 0.1 N. Total eugenol was determined using 4% Potassium Hydroxide (KOH) solution, while β-caryophyllene was analyzed using gas chromatography technique (GC) Agilent Technologies 6890N. The study of morphological aspect and essential oils characteristics of two clove varieties demonstrated large variability of this species grown in Ambon Island. Results of this study revealed that the highest oil content was found in bud oil of Zanzibar variety, while the lowest was in leaf oil of Tuni variety. In addition, Zanzibar variety tends to contain higher volatile oil content than Tuni. Furthermore, it was found that Tuni variety contained total eugenol in flower bud oil, stem, and leaf slightly higher than Zanzibar variety, with about 84%, 98%, and 78%. This finding implies that the whole clove oil from the different morphological parts of the two varieties fulfilled the standard of clove oil, although there was a slight different of a higher β-caryophyllene content. The PCA results showed that the oil content in the flower bud section was high. The increase in flower weight and oil content was not always followed by an increase in eugenol content.
