Abstract Although beeswax adulteration represents one of the main quality issues, there are still no internationally standardised analytical methods for routine control. The objective this study was to establish an procedure suitable detection using FTIR-ATR spectroscopy. For purpose study, reference IR spectra virgin beeswax, paraffin, and their mixtures containing different proportions paraffin (5 - 95%), were obtained. Mixtures used establishment calibration curves. To determine...
A Europe-Wide Experiment for Assessing the Impact of Genotype-Environment Interactions on Vitality and Performance Honey Bee Colonies: Experimental Design Trait Evaluation An international experiment to estimate importance genotype-environment interactions vitality performance honey bees colony losses was run between July 2009 March 2012. Altogether 621 bee colonies, involving 16 different genetic origins European bees, were tested in 21 locations spread 11 countries. The strains belonged...
The GC and GC/MS analyses of the solvent organic extractive from stomach bees, having collected Mentha spp. nectar, revealed presence methyl syringate (6.6%), terpendiol I (5.0%) vomifoliol (3.0%) that can be attributed to plant origin. Other major compounds bee-stomach were related composition cuticular waxes less pheromones. Organic extractives honey obtained by solvent-free headspace solid-phase microextraction (HS-SPME) ultrasonic extraction (USE) analyzed GC/MS. hotrienol (31.1%-38.5%),...
Samples of unifloral sulla (Hedysarum coronarum L.) honey from Sardinia (Italy) were analysed. To investigate the chemical composition volatiles two solvent systems used for ultrasonic extraction (USE): 1) a 1:2 (v/v) pentane and diethyl ether mixture 2) dichloromethane. All extracts analysed by GC GC/MS. These procedures have permitted identification 56 compounds that include norisoprenoids, benzene derivatives, aliphatic Maillard reaction products. Norisoprenoids major in both extracts,...
Specific rotation and carbohydrate profile of Croatian black locust (Robinia pseudoacacia L.), sage (Salvia officinalis L.) chestnut (Castanea sativa Mill.) honeys were determined. Fructose, glucose, sucrose, maltose (with cellobiose trehalose), melezitose erlose), raffinose, xylose evaluated quantified by HPLC, while specific was determined using a polarimeter. The differences in the profile, especially disaccharide trisaccharide contents, reflected different values honey types selected....
The paper examines the antiproliferative, antimicrobial and antioxidative effects of fir (Abies alba Mill.) honeydew honey from mountain region Croatia (Gorski kotar) as a potential replacement for standard antibiotics chemotherapeutic agents. Cell viability, annexin V assay flow cytometry analysis served to analyse antiproliferative effect on, apoptosis induction in cell death cancer lines: HeLa, MCF-7, SW620, CFPAC-1, MIA PaCa-2 normal diploid human fibroblasts (BJ). Antimicrobial activity...
Headspace solid-phase microextraction (HS-SPME) and ultrasonic solvent extraction (USE), followed by GC-MS/FID, were applied for monitoring the nectar (NE)/honey-sac (HoS)/honey (HO) pathways of headspace, volatiles, semi-volatiles. The major NE (4 varieties Citrus unshiu) headspace compounds linalool, α-terpineol, 1H-indole, methyl anthranilate, phenylacetonitrile. Corresponding extracts contained, among others, 1,3-dihydro-2H-indol-2-one caffeine. HoS 1,8-cineole, cis-jasmone....
Strawberry tree (Arbutus unedo L.) honey (STH) has been used since ancient times as a folk medicine remedy, especially in certain Mediterranean countries. This honey, rich phenolic content, is well recognized for its antioxidant, anti-inflammatory, and antimicrobial activities, the treatment of skin lesions gastrointestinal respiratory disorders. study investigated whether STH alleviates genome damage human peripheral blood lymphocytes produced by cytotoxic drug irinotecan. The profile was...
The aim of this study was to evaluate the influence botanical origin on fatty acids composition bee pollen and its nutritional value. seven monofloral samples from different locations Croatia were analysed. A total 26 (from C12 C24) identified with a significant difference in their shares samples, nine them common all samples. Assessing through quality indicators (high unsaturated acids/saturated ratios, high n-3/n-6 α-linolenic acid/linoleic acid very low atherogenic thrombogenic indexes)...
SummaryThe objective of this study was to compare the colony development cycle (unsealed and sealed worker brood, drone pollen strength) two Apis mellifera carnica subpopulations in distinct environments (alpine continental). At each test location were sub groups 12 colonies headed by naturally mated sister queens from either Institute Apiculture Lunz am See, Austria (AT) or Faculty Agriculture University Zagreb, Croatia (HR). Colony monitored every 14 days. The HR genotype, adapted a...
Experimental varroacidal treatments of honey bee colonies were conducted on five apiaries (EA1–EA5) situated at different geographical and climatic locations across Croatia. The aim this study was to assess the comparative efficacy CheckMite+ (Bayer, Germany), Apiguard (Vita Europe Ltd.; England), Bayvarol, C, Thymovar, (Andrma BioVet GmbH, ApiLife Var, (Chemicals Laif SPA; Vigonza, Italy) for controlling obligatory parasitic mite Varroa destructor in conditions field during summer...

Strawberry tree (Arbutus unedo L.) honey (STH), also known as "bitter honey", is a traditional medicine widely used in the Mediterranean area. Regardless of geographical origin, it usually has very high content phenolic compounds and strong antioxidant capacity. Yet, little still about effects STH, its extract (STHE), main bioactive compound - homogentisic acid (HGA) at cell level. The aim this study was to estimate total content, DPPH radical scavenging activity, ferric reducing power STH...
Goldenrod, native to North America was introduced into Europe in the 19th centuary as ornamental plant. However, this plant has become widespread and is a serious invader of abandoned fields, forest edges river banks. Goldenrod represents an important source nectar for honey bees, particularly reserve help colonies survive winter period. Although insect pollinated plant, it shed much more pollen than carried off by insects. The may atmospheric can cause hay fewer during its pollination period August.
