The present study was designed to determine the effects of the essential oil of Laurus nobilis L. (Lauraceae) and its three main components on α-glucosidase and reactive oxygen species scavenging activity. The chemical composition of the essential oil from Laurus nobilis L. leaves was analyzed by GC/GC-MS and resulted in the identification of 29 compounds, representing 99.18% of the total oil. ...

A microwave-assisted hydrodistillation protocol was modified to extract essential oils from leaves of Salvia triloba L. and Laurus nobilis L. The essential oils of these plants are generally obtained by hydrodistillation or steam distillation. The volatile compounds obtained by microwave-assisted hydrodistillation and hydrodistillation methods were analyzed by GC and GC/MS. Both distillation me...

Xylosandrus compactus (Eichhoff) (Col.: Curculionidae, Scolytinae) is an ambrosia beetle species native to subtropical Eastern Asia, with great concern due its high invasive ability. This has invaded 54 countries worldwide, including 4 European (Italy, France, Greece, and Spain); it was detected in Mallorca (Balearic Islands, Spain) October 2019. In the present work, X. recorded for first time ...

O fracionamento cromatográfico dos extratos orgânicos das folhas e galhos de Luxemburgia nobilis (Ochnaceae) forneceu o sitosterol, sitosterol-3-O-βD-glicopiranosil, friedelina, friedelinol, a mistura dos triterpenos lupeol, α-amirina e β-amirina, rutina, epicatequina, uma mistura de duas chalconas, isoliquiritigenina e 3’-hidróxiisoliquiritigenina, duas biflavonas conhecidas, amentoflavona e r...

We tested the importance of in situ microphytobenthos (MPB) and transported material (seagrass, seagrass epiphytic algae,mangroves, saltmarsh succulents and saltmarsh grass in adjacent habitats) as ultimate sources of carbon to fish caught over mudflats. We measured dC values of these 6 autotrophs and 22 fish species in the subtropical waters of Moreton Bay, Queensland, Australia. All fish dC v...

—Side-scan sonar and multibeam imagery of Glacier Bay, Alaska, revealed complex iceberg gouge patterns at water depths to 135 m on the floor of Whidbey Passage and south to the bay entrance. These previously undiscovered gouges likely formed more than 100 years ago as the glacier retreated rapidly up Glacier Bay. Gouged areas free of fine sediment supported greater biodiversity of Pacific halib...
