Study Of Fennel (foeniculum Vulgari Mill) Fruits For Major And Trace Elements Cultivated In Ethiopia

Levels of selected metals (Ca, Mg, Fe, Mn, Cu, Cr, Co, Zn, Ni, Cd and Pb) wererndetermined in fennel fruit and the soil from which it was grown. The samples wererncollected from the Addis Ababa and Gojam area (Northern Ethiopia). Oven dried fennelrnfruit was grinded and 0.5 g portion of the sample was digested by wet digestion methodrnusing 2.5 mL of HNO3 and HClO4 in quick-fit round bottom flasks (100 mL) fitted withrnreflux condenser by using Kjeldahl micro hot plate apparatus. Similar procedure wasrnfollowed for soil digestion using 2 mL HNO3 (69-72%), 4 mL 36% and 1.5 mL of H2O2rn(36%). The levels of the above elements were determined using flame atomic absorptionrnspectrometer. The highest concentration of Fe (28,000 μg/g) and Ca (23,000 μg/g) werernobtained from the soil and fennel fruit, respectively. Moderate concentrations of Mg (3,400rnμg/g and 3,300 μg/g) were obtained from the fruit and the soil, respectively. The level ofrnCd was lowest (1.91 μg/g and 2.86 μg/g) in the fruit and the soil, respectively. Thernconcentration of Pb was below the methoddetection limit.rnKey words: Fennel fruit, Foeniculum vulgari Mill, Major elements, Trace elements, Flamernatomic absorption spectrometer.
