摘要: AbstractThe adverse effects on health and environment caused by polycyclic aromatic hydrocarbons (PAHs) are critical problems. EFSA has defined 16 priority PAHs that both genotoxic carcinogenic, identified eight (PAH8) as good indicators of the toxicity occurrence in food. Food supplements containing propolis were also found to contain relatively high quantities PAHs. We report about an extractive procedure which is able purify from a content using balanced mixture ethanol water solvents. Extracts characterised for total polyphenols, vitro antioxidant activity, single classes polyphenols evaluated HPLC-ESI-MS. Obtained extracts have PAH8 specific benzo[a]pyrene below limits recommended EFSA. The reported easily applicable possible industrial productions may be adopted purification other plant n...
