Purification and Identification of Endogenous and Exogenous Minor Constituents from Vegetable Oils

Abstract Minor constituents are ubiquitous in plant origin sources, particularly plant derived oils. According to the origins of the minor constituents, factors that are responsible for their occurrence can be categorized into endogenous and exogenous factors. To date, extensive researches have been carried out to separate, purify, identify and analyze them to further asses their value as well as advise their thorough utilization or decontamination. These issues emphasizing on hydrocarbons, aldehydes, ketones, pesticides, herbicides, and trace metal compounds as well as their isolation methodologies via physical and chemical means will be covered in this review.
