Predominant and Secondary Pollen Botanical Origins Influence

Total and individual carotenoids, fatty acid composition of
total lipids, and main lipid classes of 16 fresh bee-collected pollen samples
from Romania were determined by high-performance liquid chromatography with
photodiode array detection and capillary gas chromatography with mass
detection. Analyzed samples were found rich in lutein, whereas β-criptoxanthin
and β-carotene were present in a wide range of amounts correlated with
predominant botanical origin of the samples. High amounts of lutein were correlated
with the presence of Callendula officinalis, Taraxacum officinale and Anthylis
sp. The highest amount of total lipids was found in samples where pollen from
Brassica sp. was predominant. Lipid classes were dominated by polyunsaturated
fatty acids. Saturated fatty acids were determined in variable amounts. Lipid
and carotenoid contents present great variability, explained by the various
botanical species present in the samples.
