In this study, Parinari excelsa seed was extracted with n-haxane through Soxhlet extraction method, concentrated with rotary evaporator to obtain the extract.

The study was to determine the concentrations and risks of organophosphorus pesticides (OPPs) residues in edible vegetable oils (EVOs) sold in markets in Warri, Delta State. OPPs in six edible vegetable oils purchased from local vendors in markets in Warri, Delta State were quantified with a gas chromatograph coupled with a mass spectrometry (GC-MS) after solvent extraction. The results showed concentration of the ∑14 OPPs varying from 4.10 to 22.82 ng/L. The unbranded edible vegetable oils had higher concentrations than their respective branded vegetable oils.
