The concentrations for Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn were found to be 0.037-0.063, 0.014-0.085, 0.735-1.243, 2.105-19.487, 0.104-0.592, 0.105-1.582, 0.025-0.125, and 1.024-2.583 mg kg(-1), respectively. The highest concentrations in the herbal oils were Cr, Fe, Mn, and Zn, in linseed oil, Cd and Pb in sesame oil, Cu in nettle oil, and Ni in chamomile oil, respectively. The three sample preparation methods investigated were compared and it was found that the results of TPE and WD are comparable. The statistical results show that the TPE and WD methods usually give similar results.en10.46770/AS.2018.01.005info:eu-repo/semantics/openAccessSeed OilSesameExtractionMedicineFlaxseedMetalsCdNiArticle3913845Q4WOS:0004448195000052-s2.0-85045308838Q2
