In this study, the in vitro anticholinesterase activity of the volatile oils of both O. basilicum and O. africanum was investigated and both samples showed significant activity. The major constituents of the two oils were isolated using several column chromatographies. Linalool, 1,8-cineol and eugenol were isolated from the volatile oil of O. basilicum and camphor was isolated from the volatile...

Background:Eryngium foetidum essential oils from Nigeria were investigated for the first time in order to ascertain their potency as natural antioxidants. E. foetidum is an aromatic and medicinal herb used in ethno-medicine and as a traditional spice for foods. Methods: The hydro-distilled oils of E. foetidum were subjected to gas chromatography-mass spectrometry (GC-MS) analysis. Free radical ...

Volatile esters are flavor components of the majority of fruits. The last step in their biosynthesis is catalyzed by alcohol acyltransferases (AATs), which link alcohols to acyl moieties. Full-length cDNAs putatively encoding AATs were isolated from fruit of wild strawberry (Fragaria vesca) and banana (Musa sapientum) and compared to the previously isolated SAAT gene from the cultivated strawbe...

Background: Lipase is an enzyme with immense application potential. Ester synthesis by lipase catalysis in organic media is an area of key industrial relevance. Enzymatic preparations with traits that cater to the needs of this function are hence being intensely researched. Objective: The objectives of the study were to immobilize the lipase from Bacillus sp. PS35 by cross-linking and adsorpti...

Medium-chain volatile flavour esters are important molecules since they have extensive applications in food, fragrance, cosmetic, paint and coating industries, which determine different characteristics of aroma or taste in commercial products. Biosynthesis of these compounds by alcoholysis is catalyzed by acyl-CoA:ethanol O-acyltransferases Eht1 or Eeb1 in Saccharomyces cerevisiae. In this stud...

Genus Mentha is represented by 15 taxa in Turkey, most common being Mentha longifolia, M. suaveolens, M. pulegium and M. aquatica. All are perennial herbs, flowering in summer and reproducing with the help of seeds as well as vegetatively. These taxa are widely used by locals as condiment as well as for the preparation of mint tea aginst flue, lung and stomach disorders, whooping cough, and as ...

Cantaloupe cultivar variability from various U.S. regions and growing seasons within a given year was evaluated. As expected, there was often considerable quality and volatile variation among cultivars. Eight of 11 cultivars met the standard U.S. No. 1 requirement for degrees Brix (> or =9), and in most cultivars, degrees Brix declined during fresh-cut storage at 4 degrees C. Hunter L (loss of ...

BACKGROUND: Cholesterol ester transfer protein (CETP) plays a major role in regulating the levels of LDL- and HDL-cholesterol. We previously observed a fish-oil-induced elevation of low-density lipoprotein (LDL)-and very-low-density lipoprotein (VLDL)-cholesterol concentrations and a decrease in high-density lipoprotein (HDL)-cholesterol concentration in F1B hamsters. The molecular mechanism/s ...

Abstract Anethum graveolens L. is a plant belong to umbelliferae family. The aim of this study compare the phytochemical different volatile oil extract from fresh air and commercial dry A. market in Karbala Iraq, by soxhlet apparatus for bout 24 hours, results indicated percentage oils differed significantly as result being affected type plant, A.graveolens gave height (4. 17%, while lower (2. ...
