Abstract
The concentrations of selenium in the flesh of ten date cultivars collected from different regions of Saudi Arabia were analysed using an ultraviolet/ visible spectrophotometer. The amount of selenium was found to be in the range between 1.48 and 2.96 μg/g in the ten varieties studied. The cultivar Sillaj from Al-Kharj (south-west region of Saudi Arabia) was found to contain the highest concentration of selenium (2.96 μg/g). The lowest content of selenium (1.48 μg/g) was observed in the cultivar Muneef from Riyadh region. The content of selenium in dates was compared with data for selenium content of other fruits, nuts and vegetables.
