Determination of total phenolic and flavonoid contents in selected fruits and vegetables, as well as their stimulatory effects on mouse splenocyte proliferation

Antioxidant activity index (AAI) by the 2,2-diphenyl-1-picrylhydrazyl method

Honey samples from the seven most common honey types in Slovenia were screened for total phenolic content by the modified Folin– Ciocalteu method, for potential antioxidant activity using the ferric reducing antioxidant power (FRAP) assay and by the 1,1-diphenyl-2picrylhydrazyl (DPPH) method for antiradical activity. In addition the colour characteristics of honey samples were analysed. The results of the study showed that total phenolic content, antioxidant activity and colour parameters differ widely among different honey types. Phenolic content expressed as gallic acid equivalent ranged from 44.8 mg/kg in acacia honey to 241.4 mg/kg in fir honey. Antioxidant activity was the lowest in the brightest acacia and lime honeys and the highest in darker honeys, namely fir, spruce and forest. The colour of the Slovenian honeys, analysed in this study was very variable and ranged from pale yellow to dark brown. Correlations between the parameters analysed were found to be statistically significant (p < 0.05). 2007 Elsevier Ltd. All rights reserved.

Phenolic Content and Antioxidant Activity of Six Acanthaceae from Burkina Faso

This study intended to determine and compare the microscopic and physicochemical characteristics of Burkina Fasan honey (n = 27) with those described in the Codex Standard, and to also find correlations between individual constituents. Physicochemical properties were determined using the harmonised methods of the international honey commission. Microscopic pollen analyses identified the samples as being derived from one Acacia, one Lannea, three Vitellaria, two Combretaceae, two mixed Poaceae honeydew and eighteen multifloral honey. Despite the tropical ambient temperature, all the samples were nevertheless well within the limits of the Codex Standard for levels of hydroxymethylfurfural, reducing sugars, proline and diastase activity. Only 7.4% (ash), 14.8% (free acidity and pH) and 22.2% (moisture) of samples exceeded the Codex-permitted limits. A highly significant correlation was found between pH and ash content (r = 0.77; P < 0.001). The training of non-professional beekeepers in beekeeping practice is suggested to improve the quality of Burkina Fasan honey.
