Smoking and/or grilling, when carried out with traditional methods involving direct contact wood combustion fumes, is responsible for high contamination levels carcinogenic polycyclic aromatic hydrocarbons (PAHs). The aim of this work was to investigate the PAH content different smoked or grilled meat and fish products commonly consumed in Nigeria. A rapid method microwave-assisted saponification simultaneous extraction followed by solid-phase (SPE), high-performance liquid chromatography...

Abstract Background The development of resistance to many antibiotics currently in use has necessitated the search for more effective alternatives. Plants have been used ethnomedicine different parts world treat various diseases. Many studies on plants confirmed their medicinal potentials and led isolation characterization several potential drug candidates. This study investigates leaves Icacina trichantha antimicrobial properties seeks identify compounds responsible observed activities. are...

To determine the physicochemical characteristics of feldspar in study area, eighteen fresh rock samples were randomly collected. The photographs and locational coordinates sample points taken using a sledgehammer, geologist’s hammer, camera, global positioning system device. Thin sections freshly prepared observed under hand lenses microscope. remaining subjected to geochemical mineralogical analysis. chemical analysis collected showed its type quality. It meets British International...

The bioconcentration levels of 3 non-essential elements (Pb, Cd and Ni) have been investigated in three different seafoods; Fish (Tilapia zilli), Crab (Callinectes sapidus) periwinkle (Littorina littorea), to investigate the ecosystem health status Ondo oil-polluted coastal region, Nigeria. seafood samples were chosen based on their popularity as a food source potential species contain high metals past research results. Metal concentrations biota showed marked interspecific differences with...

Abstract In the course of our search for new insect antifeedant substances from plants, we have devised an improved leaf‐disk bioassay. Our system allows accurate measurement consumed disk surfaces, using a video camera interfaced with computer. The scanned image leaf disks is stored, and eaten areas are measured help video‐image analysis software. This method precise quantification activity tested on material. was applied to screening Hokkaido plants activity. Out 206 samples, seven...

The essential oil of the aerial parts Chenopodium ambrosioides L. has been isolated by hydrodistillation and analyzed using GC-MS. major components were found to be alpha-terpinene (63.1%), p-cymene (26.4%) ascaridole (3.9%). displayed no antibacterial activity against either Gram-positive bacteria Bacillus cereus or Staphylococcus aureus, Gram-negative bacterium Escherichia coli (MIC=1250 microg/mL). A cluster analysis C. oils reveals at least seven distinct chemotypes: ascaridole,...

The black turtle bean (Phaseolus vulgaris L.) is popular among the people of Bokkos in Plateau State, Nigeria where it cultivated and locally known as “Kwakil”. effects different processing methods (boiling, cooking, roasting, sprouting fermenting) were investigated on fatty acid composition, physicochemical parameters antinutritional factors seeds. All analyses carried out using standard analytical techniques. results showed that oleic linoleic most concentrated acids raw processed samples...

Microcrystalline cellulose was prepared from wastes of Tithonia diversifolia, inflorescence stems Musa sapientum, and paradisiaca by soda-anthraquinone-ethanol pulping method.They were bleached sodium chlorite then alpha-cellulose isolated, followed preparation microcrystalline cellulose.The study revealed the effect various processing stages on properties obtained.Yields more than 80% obtained.Fourier transform infrared (FTIR) solid state 13 C Nuclear magnetic resonance ( NMR) confirmed...

The methanol extracts of two edible mushrooms; Termitomyces robustus (ewe) and Lentinus squarrosulus (erirokiro) were screened for phytochemicals medicinal importance the chemical profile investigated using standard analytical methods with aim assessing their health promoting properties. Both mushrooms tested positive to flavonoids, saponin, tannin terpenoid but negative steroid, anthraquinone phlobatannin. results proximate compositions in % were; moisture contents (7.22 ± 0.07; 11.03...

Polyphenols are known for their bioactive potentials and have been used as drugs preservatives decades. The drive around this research is to estimate the usefulness of bananas plantain bracts. bracts banana (Musa acuminata) paradisiaca) were investigated chemical composition, antibacterial, antioxidant capacity. result proximate analysis revealed appreciable amount moisture content (8.45%; 7.83%), crude protein (1.53%; 1.57%), fiber (21.2%; 16.5%), fat (2.01%; 2.25%), ash (16.60 %; 15.10%),...

The use of thermochemical processes to convert biomass into energy products has continued allay apprehensions arising from increasing depletion fossil fuels and growing demand. Pyrolysis (bio-oils bio-chars) cocoa pods plantain peels have been characterized. Products distribution for pod peel was 29.4% 38.1% condensate; 46.5% 38.5% bio-char; 24.1% 23.4% noncondensable gas respectively. Bio-oils the wastes were found possess low acidity improved stability upon storage. Over 70% oleic acid...

Carboxymethyl cellulose (CMC) was prepared from Gliricidia sepium and Cola gigantea with yields of 1.59 g/g 1.76 g/g, respectively. The pH the products were weakly acidic (6.47 6.54, respectively). sodium chloride content 0.22 for C. CMC 0.27 G. CMC, while degree substitution 0.46 0.51, swelling capacity 802%, which higher than 519% C CMC.
