Medicinal plants gained momentous support in the recent era for their therapeutic potential. The core objective of the research study was to characterize the indigenous variety of black cumin (Nigella sativa L.), locally known as “Kalonji” and its fixed and essential oils. Compositional analysis revealed that it contains appreciable quantities of carbohydrates, proteins and fats. Moreover, pota...

The volatile constituents of taheebo (the dried inner bark of Tabebuia impetiginosa Martius ex DC) were isolated by three methods: solvent-assisted flavour evaporation (SAFE); steam distillation under reduced pressure, followed by continuous liquid–liquid extraction (DRP-LLE); and high-flow dynamic headspace sampling (including closed-loop stripping) (DHS). The extracts were analysed qualitativ...

Rumex dentatus L. and Rumex vesicarius L., of the family Polygonaceae, are edible herbs growing wild in Egypt. Their lipoid constituents were examined by both liquid chromatography/mass spectrometry (LC/MS) and by gas chromatography/mass spectrometry (GC/MS). Their essential oil compositions consisted mainly of thujene, limonene, fenchon, estragole, and anethole but at largely different concent...

The growing concerns of consumers on the use of antibiotic as a growth promoter in livestock feed have fueled the interest in alternative products. In the recent years a group of natural product known as phytogenic has been a focus of several studies. Phytogenics are a heterogeneous group of feed additives originating from plants and consist of herbs, spices, fruit, and other plant parts. These...

Many plant essential oils and their terpenoid constituents possess bioactivities including insecticidal activity, and they sometimes act synergistically when mixed. Although several hypotheses for this have been proposed, the underlying mechanism has not been fully elucidated thus far. In the present study, we report that in larvae of the cabbage looper, Trichoplusia ni, most synergistic or ant...

Catalyst is the key for hydrodeoxygenation (HDO) of lignin derivatives to produce alkyl aromatics and cycloalkanes, components 100% sustainable aviation fuels (SAF). Mono bi-functional catalysts nickel (Ni) heterophosphotungstic acid (HPW) supported on SBA-15 carbons were prepared, characterized evaluated HDO derived trans-anethole. The structure was intact but its surface area pore volume decr...
