Abstract

The study investigated the concentration of pesticides in cotyledon and testa of Moringa oleifera collected

from a garden in Ado-Ekiti. Gas chromatographic analysis was employed for the pesticides determination

after careful extraction and florisil cleanup. The concentration (µg/kg) of pesticides in the cotyledon ranged

from 0.031 (2, 4, 6-trichlorophenol) to 0.313 (oxamyl), while the testa ranged from 0.004 (pyriproxyfen)

to 1.99 (cypermethrin). Oxamyl, cyanazine, fenvalerate, chlorpyrifos, aldrin and phosphine were the most

concentrated pesticides with trend of cypermethrin ?oxamyl ? cyanazine ? fenvalerate ? phosphine ?

chlorpyrifos ? aldrin. 55.9% of the pesticides had values in the cotyledon greater than the testa. Residual

levels of these pesticides were below the maximum permissible limits set by the European Union (EU)

Commission.
