Pyrrolizidine alkaloids in honey and bee pollen.
A total of 3917 honey samples and 119 'bee pollen' samples (pollen collected by honeybees) were analysed for pyrrolizidine alkaloids (PAs). Some 0.05 M sulphuric acid was used for extraction followed by a clean-up step by means of solid-phase extraction. Separation and detection was achieved by target analysis using an LC-MS/MS system. PAs were found in 66% of the raw honeys (bulk honey not yet...
متن کاملPyrrolizidine alkaloids of Echium vulgare honey found in pure pollen.
The pyrrolizidine alkaloids previously identified in floral honey attributed to Echium vulgare (Boraginaceae) have been detected (8000-14 000 ppm) in pure pollen collected from the anthers of Echium vulgare. Pyrrolizidine alkaloids and/or their N-oxides were isolated from the aqueous acid extracts of pollen by use of strong cation-exchange, solid-phase extraction and identified by liquid chroma...
متن کاملDetection of pyrrolizidine alkaloids in commercial honey using liquid chromatography-ion trap mass spectrometry.
Pyrrolizidine alkaloids (PAs) are known secondary plant metabolites which can cause hepatotoxicity in both humans and livestock. PAs can be consumed through the use of plants for food, medicinal purposes and as contaminants of agricultural crops and food. PA contaminated grain has posed the largest health risk, although any PA contamination in our food chain should be recognised as a potential ...
متن کاملQualitative and Quantitative Determination of Pyrrolizidine Alkaloids of Wheat and Flour Contaminated with Senecio in Mazandaran Province Farms
The Pyrrolizidine Alkaloids (PAs) are a group of chemicals found in a variety of plant species throughout the world. These toxic alkaloids are distributed mainly in Senecio (Compositae), Crotalaria (Legominosae) and Heliotropium (Boraginaceae) species. Plants containing these alkaloids cause significant mammalian morbidity and mortality, especially in humans. Upon ingestion, metabolic activatio...
