Tocotrienol, a member of vitamin E family. The natural vitamin E family comprises four tocopherol and four tocotrienol isomers, namely alpha (α), beta (β), gamma (γ) and delta (δ). Throughout the past 30 years, very few vitamin E studies focused on tocotrienols although tocotrienols constitute half of the entire vitamin E family. In recent years, tocotrienol research has gained much prominence due to its potential health attributes. Tocotrienols are not only structurally different from tocopherols, but also possess biological functions which are not shared by the tocopherol isomers.
