Abstract. Using commercially available foods, such as avocado and vegetable oils, students in a Biochemistry lab course mini research project extracted and characterized vitamin E using several bio-analytical techniques such as UV-Vis spectroscopy, cyclic voltammetry and thin layer chromatography. The students learned about the physical and chemical properties of vitamin E. Their results corresponded reasonably well with data found the literature. This project was successful since it allowed the students to design and carry out their own experiments and present their data as a poster to the entire class.

Key Words: Laboratories and Demonstrations; biochemistry; vitamin E; tocopherol; tocotrienol; mini research project; cyclic voltammetry
