Objective: To analyse and compare the major chemical components in the flower buds, pedicels and leaves of Syzygium aromaticum by Gas-Chromatography Mass spectrometry technique. Methods: Healthy and mature flower buds, pedicels and leaves were shade dried and pulverized using a mechanical grinder. The powder was successively extracted with ethanol (40-60o C). The extracts were concentrated under reduced pressure in a rotary evaporator. The ethanolic extracts of the plant parts such as leaves, pedicels, and buds were used for GC-MS analysis.Results: The major constituent is eugenol. Pedicels contain 79.75% eugenol, buds contain 74.12% eugenol and leaves contain 51.03% eugenol. In addition to eugenol, other important components are Acetyl eugenol, Caryophyllene, Humulene and Caryophyllene oxide.Conclusion: Eugenol has a wide range of medicinal properties such as antiseptic, anaesthetic, analgesic anti-inflammatory. Commercially pedicel is not used for eugenol extraction. Present study has revealed that it could be used as a promising one in pharmaceutical industry in addition to flower buds.

In this investigation plant oil and powder of E. aromatica were evaluated under laboratory conditions to determine their toxicity, fumigant effect and impact on F1 progeny of S. oryzae and T. castaneum adults. Essential oil and powder of flower buds obtained from Eugenia aromatica were purified and analyzed by Gas-Chromatography–Mass Spectrometer (GC-MC). The results obtained showed that the two products of E. aromatica had good disorders on the all tested parameters. For toxicity and fumigant effect the oil was the premier compared to powder. In addition, that the two products completely prevented the F1 emergence of the two insects. In respect of the toxicity and fumigation the T. castaneum was more tolerant than S. oryzae adults. Phytochemical analysis showed that euegnol (89.62%) was the premier component of essential oil, while euegnol (78.66%), caryophyllene (6.30%), -a-Terpinyl acetate (1.35%) were the major components for its powder. These findings suggest application of E. aromatica products as suitable tools as a potential source of insecticides, alternative to synthetic insecticides or using these products in integrated pest management program against stored product insects, especially S. oryzae or T. castaneum adults.

Important Medicinal Plant

The fruit of Syzygium aromaticum is an important medicinal plant was subjected to phytochemical screening and antimicrobial effect of methanol, ethyl acetate and acetone extracts. Antimicrobial activity was analyzed by agar well diffusion method against gram positive and gram negative bacteria. The phytochemical analysis carried out revealed the presence of alkaloids, coumarins, catechins, flavanoids, phenols, saponins, terpenoids, tannins and steroids in various solvent extracts. Methanol extract of S. aromaticum showed good antimicrobial activity against Bacillus subtilis, Pseudomonas aeruginosa and Staohylococcus aureus. It has been showed that the methanol extracts had wider range of activity on these organisms than the acetone and ethyl acetate extracts, which indicates that the methanol extracts of selected plants may contain the active components. The use of plant extracts with known antimicrobial properties can be of great significance in therapeutic treatments.

Antidermatophytic Activity

In order to provide an effective alternative for efficient management of dermatophytosis, we evaluate in vitro the antioxidant and antiradical potentials of the essential oil of the dry flower buds of Syzygium aromaticum and its antidermatophytic activity against Epidermophyton floccosum and Trichophyton soudanense, For this purpose, the essential oil was obtained by hydrodistillation through a Clevenger apparatus and the antioxidant and antiradical potentials were evaluated by the ferric reducing antioxidant power (FRAP) and the trapping of the ABTS•+ radical methods, respectively. The evaluation of the antidermatophytic activity was made by the agar incorporation method. The results showed that the essential oil reduced ferric iron (Fe3+) to ferrous iron (Fe2+) in a more significant manner than BHT (reference antioxidant). Moreover, the antiradical power of the essential oil was twice greater than that of BHT. Furthermore, the essential oil inhibited the mycelial growth of the two dermatophytes, with 500 ppm and 1000 ppm of minimal inhibitory concentrations against Epidermophyton floccosum and Trichophyton soudanense, respectively. This activity was greater than that of griseofulvin whose minimal inhibitory concentration was greater than 4000 ppm against both studied germs. These findings show that, withon the framework of safeguarding human lives and protecting the environment, the essential oil from the dry flower buds of Syzygium aromaticum appeared as reliable alternative for the treatment of dermatophytosis caused by Epidermophyton floccosum and Trichophyton soudanense. Our results lay scientific foundation toward the promotion and development of Cameroonian biodiversity in treatments of dermatophytosis.
