Results: All materials tested demonstrated different degrees of sorption and solubility. The glass ionomer cement had the best value for sorption. The zinc oxide eugenol and eugenol free cements had lower water sorption than the zinc polycarboxylate and zinc phosphate cements were evaluated. Some materials retained water in their structure and thus compensated for any loss of mass due to dissol...

Fruit plants produce various volatile compounds that emit distinct aroma characteristics and contribute to their flavor qualities. However, some of these substances, especially hydroxyl-group molecules, are in non-volatile glycosylated forms. This study aimed determine free glycosidically bound three Okinawan pineapple cultivars (‘N67-10′, ‘Yugafu’, ‘Yonekura’). The components squashed juice we...

BACKGROUND Excessive production of free radicals has been implicated in many diseases including cancer. They are highly reactive and bring about oxidation of biomolecules i.e., proteins, lipids and nucleic acids which are associated with many degenerative diseases. Natural products acting as antioxidants have ability to neutralize free radicals and their actions and hence they mitigate their ha...

A 5-wk trial with 96 ((Landrace× Yorkshire)×Duroc) pigs (BW = 26.56±0.42 kg) was conducted to investigate the effect of eugenol and cinnamaldehyde as feed additive in growing pigs. Pigs were assigned to 1 of 3 treatments in a randomized complete block design according to their sex and BW. Each treatment contained 8 replications with 4 pigs (2 gilts and 2 barrows) per pen. Treatments included: c...

Syzygium aromaticum merupakan tanaman obat yang terkenal akan kegunaannya di dunia medis. Tanaman ini mengandung minyak esensial memiliki banyak bioaktivitas yakni eugenol. Penelitian bertujuan untuk mengetahui potensi senyawa eugenol dan turunannya sebagai inhibitor HIV-1 Protease (PR) kandidat antivirus HIV-1. Ligan digunakan dalam penelitian adalah eugenol, metil asetil isoeugenol. Hasil men...

The anthelmintic activity of the eugenol against the fish parasite Gyrodactylus sp. was evaluated. After 1-h exposure to 5 and 10 mg/L eugenol, mortality of the parasites was near 80 and 90%, respectively. The concentrations used in the antiparasitic test were not toxic to Daphnia pulex (LC50 42.5 mg/L).

The essential oil of the leaves of P. racemosa var. terebinthina and P. racemosa var. grisea were examined by GC and GC/MS. The major constituents were alpha-terpineol acetate (27%), alpha-terpineol (20%) and 4-methoxy eugenol (12.6%) for Pracemosa var. terebinthina and 4-methoxy-isoeugenol (75.2%) and 4-methoxy-eugenol (4.5%) for P. racemosa var. grisea.

The winemaking process involves the alcoholic fermentation of must, often followed by malolactic fermentation (MLF). The latter, mainly carried out by the lactic acid bacterium Oenococcus oeni, is used to improve wine quality when acidity reduction is required. Moreover, it prevents microbial spoilage and improves the wine's organoleptic profile. Prior observations showed that O. oeni is able t...
