Pollen Analysis of Honey Bought from Sokoto Metropolis
N. Salisu, J. Umar and J. Musa

ABSTRACT
Microscopic examination of pollen grains determined the botanical origin and geographical location of honey. This study was aimed at determining the botanical sources of honey using qualitative and quantitative pollen analysis. Ten grams (10g) of honey was diluted with 8ml of distilled water and centrifuged at 2,500 rpm for ten minutes, and the sediments were used to analyse the pollen microscopically. Three thousand six hundred and ninety-two (3692) pollens belonging to fifteen (15) plant species were identified. Among the pollen types, Azacdirachta indica and Aspilia africana were found in all the samples. Azadirachta indica was found to be higher ranging from 27.23% to 47.98%, while Coffea arabica and poacea was rare. Samples A, B and E were classified as unifloral honey with Azadirachta indica dominating the pollen assemblage, with a 47.96%, 51.21% and 45.12% relative frequency respectively. Samples C and D are multi-floral honey with a diverse assemblage of frequency classes of pollen and no dominant pollens. The result of pollen analysis showed a wide variety of botanical sources of honey. It is recommended that the pollen analysis of the honey sample produced in the area should be conducted
