This work was undertaken to explore antityrosinase and antioxidant activities of twenty essential oils of edible Thai plants. Antityrosinase activity against mushroom tyrosinase was examined by means of the dopachrome method using L-dopa as an enzymatic substrate. The essential oil of Cymbopogon citratus had the highest level of antityrosinase activity, followed by that of Ocimum canum with enz...

Presently, functional foods and nutraceuticals are gaining immense importance in the prevention of various maladies through dietary regimen module. Consumption of fruits and vegetables based diet has pursuit a range of bioactive components, especially phytochemicals targeting life threatening ailments. In this context, lycopene is an extensively studied antioxidant potentially present in waterm...

The essential oil obtained from leaves of Melissa officinalis L. (Family of Lamiaceae) growing in Algeria, was investigated for its chemical composition and in vitro antimicrobial activity. The chemical composition was determined by hydrodistillation and analyzed by GC/MS and GC-FID. Sixty-three compounds were identified in the essential oil, representing 94.10 % of the total oil and the yields...

The present work evaluated the chemical composition and the DNA protective effect of the essential oils (EOs) from Lippia alba against bleomycin-induced genotoxicity. EO constituents were determined by Gas Chromatography/Mass Spectrometric (GC-MS) analysis. The major compounds encountered being citral (33% geranial and 25% neral), geraniol (7%) and trans-β-caryophyllene (7%) for L. alba specime...


 El trabajo tiene como objetivo analizar la conformación de burocracia estatal destinada al cuidado niños y jóvenes en década 1920 dos instituciones del in- terior país. Si bien los especialistas época ge- neral coincidían sobre las características que debía tener el personal destinado a esa tarea, posibilidades Estados provinciales estuvieron lejos contar con dichos funcionarios. En este...

The peel which is the primary waste of citrus fruit processing usually discarded. But these peels are good source pectin, phenols, flavonoids, and limonene. can be used to extract essential oil that in food system. present study aimed extraction analyse chemical composition by hydrodistillation soxhlet methodThe optimum condition for method was standardized efficient at 95 °C. time 3 hours with...

The concentration and the chemical composition of the essential oils obtained from different samples of Cymbopogon citratus were evaluated. Among the 12 samples investigated (11 dried leaf samples and fresh plant leaves), seven presented essential oil concentrations within the threshold established by the Brazilian legislation. The moisture content was also determined and the majority of the sa...

ABSTRACf We propose a methOd of parallelizing bottortl-up-evaluation of logic programs. The method is distinguished by the fact that it is pure i.e., does not require inU7procesSor communication, <r synchronization overhead The method cannot be used to parallelize every logic program, but we syntactically charac~erize several classes pf logic programs to which the method can be applied (e.g., t...

Glutathione S-transferases (GSTs) enzymes are critical antioxidant and detoxification system responsible for long-term existence of nematodes in host species. Hence, 16 phytochemicals predicted and reported to have potential nematicidal activity have been docked to GST enzyme of Meloidogyne incognita to assess their binding affinity and inhibitory activity. In vitro effects of these phytochemic...

The medial axis transform provides an alternative r epresentation of geometric models that has many use ful properties for analysis modelling. Applications include decomposition of ge neral solids into sub regions for mapped meshing, i dentification of slender regions for dimensional reduction and recognition o f small features for suppression. In order to serve these purposes effectively, it i...
