Elaeis guineensis
In nature, tocotrienols are present in many plants and fruits. The palm fruit ("Elaeis guineensis") is particularly high in tocotrienols, primarily gamma-tocotrienol, alpha-tocotrienol and delta-tocotrienol. Other cultivated plants high in tocotrienols includes rice, wheat, barley, rye and oat. In annatto, tocotrienols are relatively abundant (only delta- and gamma-tocotrienol however) and it contains no tocopherols.
