The physicochemical parameters, sugars, minerals and volatile compounds were selected in current work as the crucial parameters for evaluating multifloral honeys produced by Apis cerana cerana Fabricius, Apis dorsata Fabricius and Lepidotrigona flavibasis Cockerell. A summarized physicochemical profile of multifloral honeys exhibited great variability, which was quite different from that of A. mellifera honey, regarding color (83.86–328.36 mmPfund), ash (0.30–0.34 g 100 g −1 ), soluble solid (74.72–80.41 °Brix), diastase activity (5.48–6.70 °Göthe), electrical conductivity (0.40–0.55 mS cm −1 ), free acidity (0.51–0.85 mol kg −1 ), hydroxymethylfurfural (0–39.28 mg kg −1 ), moisture (18.65–23.80%) and pH (3.73–3.95). Fructose and glucose were the major carbohydrates in Apis spp. honeys but high level of maltose was present in L. flavibasis honey. The potassium , zinc and calcium were abundant elements in multifloral honeys. The principal component analysis was applied to discriminate honeys from different bee species by cobalt, sulfur, magnesium, color, maltose, pH, free acidity, potassium, molybdenum, F/G, HMF and iron, and it was concluded that L. flavibasis honey had better quality compared to the other honeys. Moreover, the specific volatile compounds detected in A. dorsata and L. flavibasis honeys were more than A. cerana cerana honey, which could be used as the characteristic markers discriminating honey samples.

Honey is a complex food product, and has been linked to a number of substantial health advantages. The aim of this study was to assess the phenolic compounds, organic acids, microbial community, antioxidant activity, and antimicrobial activity of multifloral honeys produced by Apis cerana cerana , A. dorsata , and Lepidotrigona flavibasis in Hainan province, China. Our results illustrated that chlorogenic acid was the major phenolic component in all honeys. L. flavibasis honey showed the greatest antioxidant activity (DPPH IC 50 value, 7.66 mg/mL; FRAP value, 5217.06 µmol TE/kg), as well as the highest levels of proline (548.64 mg/kg), total flavonoid (11.67 mg QE/100 g), total phenolic (132.73 mg GAE/100 g), and Lactobacillus (96.28 %). Besides, all honeys were found to have a broad spectrum of antibacterial activity. Overall, our data imply that Hainan honeys, particularly stingless bee honeys, have been beneficial components of human diets.

Social pollinators such as honey bees face attacks from predators not only at the nest, but also during foraging. Pollinating honey bees can therefore release alarm pheromones that deter conspecifics from visiting dangerous inflorescences. However, the effect of alarm pheromone and its chemical components upon bee avoidance of dangerous food sources remains unclear. We tested the responses of giant honey bee foragers, Apis dorsata , presented with alarm pheromone at a floral array. Foragers investigated the inflorescence with natural alarm pheromone, but 3.3-fold more foragers preferred to land on the ‘safe’ inflorescence without alarm pheromone. Using gas chromatography–mass spectrometry analysis, we identified eight chemical components in the alarm pheromone, of which three components (1-octanol, decanal and gamma-octanoic lactone) have not previously been reported in this species. We bioassayed six major compounds and found that a synthetic mixture of these compounds elicited behaviors statistically indistinguishable from responses to natural alarm pheromone. By testing each compound separately, we show that gamma-octanoic lactone, isopentyl acetate and (E)-2-decen-1-yl acetate are active compounds that elicit significant alarm responses. Gamma-octanoic lactone elicited the strongest response to a single compound and has not been previously reported in honey bee alarm pheromone. Isopentyl acetate is widely found in the alarm pheromones of sympatric Asian honey bee species, and thus alarmed A. dorsata foragers may produce information useful for conspecifics and heterospecifics, thereby broadening the effects of alarm information on plant pollination.
