Leptosperin, a novel glycoside of methyl syringate, is exclusively present in manuka honey derived from the Leptospermum species Leptospermum scoparium. Quantification of leptosperin might thus be applicable for authentication of honey. The concentration of leptosperin has high linearity with antibacterial activity. We established a monoclonal antibody to leptosperin and characterized the antib...

The present study aims the identification and quantification of trace elements in two types of honey samples: Orchard honey and Wild honey from mainland Portugal. Chemical elements content was assessed by Instrumental Neutron Activation Analysis (INAA). Concentrations were determinated for Ag, As, Br, Ca, Cl, Cs, Cu, Fe, K, La, Mg, Mn, Na, Rb, Sb, Sc, U, V and Zn. The nutritional values of both...

The anti-bacterial property and preservative nature of honey has been studied by evaluating the role of hydrogen peroxide in these properties, against bacterial strains isolated and identified from pasteurized milk samples. The antibacterial property of honey examined by agar incorporation assay and turbidometry, indicated a concentration dependent inhibition of bacterial growth in all catalase...

The major compounds in honey are carbohydrates such as monosaccharides and disaccharides. The same compounds are found in cane-sugar concentrates. Unfortunately when sugar concentrate is added to honey, laboratory assessments are found to be ineffective in detecting this adulteration. Unlike tracing heavy metals in honey, sugar adulterated honey is much trickier and harder to detect, and tradit...

Using precise pollen species determination by conventional microscopic methods, accompanied by molecular genetic markers, we found bees collect GMO (genetically modified) soybean pollen and incorporate it in Yucatan honey. Honey comb samples from Las Flores, Campeche, Mexico, often contained soybean pollen. Pollen in honey was analyzed in nine samples; six contained substantial soy pollen and t...

Among the panoply of food products, honey has been used since prehistoric times as an effective healing, antiseptic, antioxidant and antibacterial therapy. The present research aimed to investigate erstwhile undocumented litchi honey samples from Bangladesh, for its antioxidant and physico-chemical parameters that may increase knowledge of product quality in a given geographic area, as well as ...

Effect of honey on plasma concentration of diltiazem after oral and intravenous administration in rabbits, has been studied. For oral study, single dose of diltiazem (5 mg/kg, p.o.) along with saline was administered to New Zealand white rabbits (n=8). Blood samples were collected at 0, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6 and 8 hr after drug administration from marginal ear vein. After a washou...

This study develops a method for the discrimination and prediction of honey samples from various botanical origins. The method was based on the nontargeted volatile profiles obtained by solid-phase microextraction and gas chromatography-mass spectrometry (SPME-GC/MS) combined with chemometrics. The blind analysis of nontargeted volatile profiles was carried out by SPME-GC/MS for 87 authentic ho...

Selected physicochemical parameters, total phenolics, flavonoids and free radical scavenging activity of honey samples from the northern savannah region and southern rainforest ecosystems of Nigeria were investigated. Moisture and ash content of most samples were within acceptable limits. Total phenolic content ranged from 23.92 to 82.34mgGAE/100g for both ecosystems. Flavonoids varied between ...
