The fatty-acid composition and botanical origin of 14 honey bee (Apis mellifera) pollen load samples acquired in shops and apiaries in Minas Gerais and Sao Paulo states, Brazil, were determined. The fatty acids presented a variable composition among these samples. All samples contained oleic, linoleic and arachidic acid. Only one sample did not present palmitic acid. The unsaturated fatty-acid level varied from 18.6% to 55.9% of the total fatty-acid composition, suggesting that pollen is a good source of unsaturated fatty acids to the diet. Several pollen types were identified. Eucalyptus (Myrtaceae) and Eupatorium (Asteraceae) pollen types were the most common among those sampled. These data might help the regulatory agencies establish quality parameters for pollen produced in Brazil. There are no additional data available on Brazilian pollen fatty acid composition.
