Rapid analytical method for the determination of aflatoxins in plant-derived dietary supplement and cosmetic oils.

Consumption of edible oils derived from conventional crop plants is increasing because they are generally regarded as healthier alternatives to animal-based fats and oils. More recently, there has been increased interest in the use of alternative specialty plant-derived oils, including those from tree nuts (almonds, pistachios, and walnuts) and botanicals (borage, evening primrose, and perilla) both for direct human consumption (e.g., as salad dressings) and for the preparation of cosmetics, soaps, and fragrance oils. This has raised the issue as to whether or not exposure to aflatoxins can result from such oils. Although most crops are subject to analysis and control, it has generally been assumed that plant oils do not retain aflatoxins due to the high polarity and lipophobicity of these compounds. There is virtually no scientific evidence to support this supposition, and available information is conflicting. To improve the safety and consistency of botanicals and dietary supplements, research is needed to establish whether or not oils used directly, or in the formulation of products, contain aflatoxins. A validated analytical method for the analysis of aflatoxins in plant-derived oils is essential to establish the safety of dietary supplements for consumption or cosmetic use that contain such oils. The aim of this research was therefore to develop an HPLC method applicable to a wide variety of oils from different plant sources spiked with aflatoxins, thereby providing a basis for a comprehensive project to establish an intra- and interlaboratory validated analytical method for the analysis of aflatoxins in dietary supplements and cosmetics formulated with plant oils.
