Essential oil from clove buds syzygium aromaticum L. Merr. ＆ Perry （Myrtaceae） was extracted using petroleum ether in Soxhlet apparatus. The resultant oil contained eugenol （48.92%）, caryophyllene （18.55%）, α-caryophyllene （3.25%）, eugenol acetate （23%）, cis-13-docosenamide （3.2 1%）, presenting more than 96% of the oil. This oil was examined as a fumigant and repellent agent against adults of the red flour beetle, Tribolium castaneum. Data showed that various concentrations of the oil have revealed dramatic repellent activity against the tested insect, where it gave 100% repellency by 1.0, 0.8, and 0.2% clove oil at 4, 8, 10 min, respectively. The RTs0 and RT95 were 1.1 and 8.0 min at 0.2% and 0.4, 2.6 min at 0.8%, respectively. In addition, fumigation assay has also exhibited strong fumigant activity toward the adults of T. castaneum. At 100 μL oil/L air, mortality was 75, 80 and 100% after 6, 7, and 8 days exposure period with LCs0 and LC95 17 and 70 μL/L air, respectively. The utilization of clove oil for its potential effects against stored product insect is discussed.

Alpinia galanga, Eurycoma longifolia Jack and syzygium aromaticum have been widely used in traditional medicine for decades. Antimicrobial activities for individual crude extract were well established. Crude methanolic extracts of Alpinia galanga, Eurycoma longifolia Jack and syzygium aromaticum and the combination for all extracts were tested using well diffusion techniques against Saccharomyces cerevisiae （ATCC 9763） and Escherichia coli （ATCC 25922）. The mixed extracts were prepared based on the concentration ratio of 50 μg/μL which are 1：1, 1：1：1 and 1：2：2. Single syzygium aromaticum extract showed higher inhibition zone on Saccharomyces cerevisiae compared to Escherichia coli. There is reduction in diameter of inhibition zone for single extract and mixture extracts either in combination of two or three extracts tested on Saccharomyces cerevisiae and Escherichia coli growth but they are not significant. In conclusion, syzygium aromaticum showed highest activity against Saccharomyces cerevisiae and Escherichia coli. Reduction in diameter of inhibition zone indicated that Alpinia galanga and Eurycoma longifolia Jack extracts had antagonistic effect with syzygium aromaticum.
