background pycnocycla spinosa decne. ex boiss is an aromatic plant which showed relaxant effects on isolated ileum contractions and antidiarrheal activity. thirty four components have been extracted from p. spinosa essential oil, of which several major constituents were found to show seasonal variation. objectives the aim of this work is to evaluate the diurnal variation of its oil constituents...

This study aimed to determine the characterization of essential oils in turmeric leaves and rhizomes using Chromatography-Mass Spectrophotometry (GC-MS). In this study, were obtained by steam distillation on seven months old Panjalu area. Based research results, there eight similar compounds, alpha-phellandrene, 1,3-cyclohexadiene 1-methyl-4-(1-methyl ethyl), P-Cymene, D-Lymonene, Eucalyptol, a...

Pine resin has been used as a traditional health-promoting medicinal food in Turkey and some countries for centuries. In the present study, antioxidant potential monoterpene profile of 13 pine samples purchased from herbalists different provinces were investigated. According to analysis results, there differences between samples, especially terms color properties. The experimental results demon...

Background & Aim: The aim of this study was to investigate the antibacterial, antifungal properties and chemical composition screening of essential oils of Satureja khuzestanica Jamzad and Satureja hortensis L. Experimental: For determination of antibacterial and antifungal activity of these essential oils, Staphylococcus aureus...

The alkynylation of naphthols takes place with total regiocontrol at the peri position of the hydroxyl group in the presence of [RuCl2(p-cymene)]2 as the catalyst. This reaction features high functional group tolerance. The related ortho-alkynylation of benzoic acids proceeds under similar conditions and also shows wide functional group tolerance. Both reactions proceed through metalation, inse...

Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. (Xoo) is one of the most damaging diseases to rice across world. Various chemicals have been employed so far for management bacterial blight. On other hand, these compounds are ecosystem and an impact on non-target species such as humans animals. As a result, there need create new natural inhibitor BLB management. Deformylase (PDF) en...

Hydrogenation of levulinic acid (LA) to γ-valerolactone (GVL) was studied by using mono- and bidentate p-cymene ruthenium(ii) N-heterocyclic carbene (NHC) complexes as catalyst precursors. In water, all complexes were found to be reduced in situ to form ruthenium nanoparticles (RuNPs) with a high hydrogenation activity. In organic solvents, complexes with monodentate NHC ligands also formed nan...
