Abstract

1. δ-Tocotrienol (8-methyltocotrienol) was isolated from the latex of Hevea brasiliensis. This new member of the tocopherol family is a pale-yellow oil at room temperature. 2. The properties of δ-tocotrienol are very similar to those of δ-tocopherol and the small differences can be explained by the change in side chain. 3. The ultraviolet and infrared spectra of δ-tocotrienol were determined and a conversion factor for use with the Emmerie–Engel reaction was worked out. Details are given for the chromatography of δ-tocotrienol on thin layers (adsorption and partition) and reversed-phase paper, and the nitroso derivatives were formed. 4. An ethyl carbonate ester of δ-tocotrienol was prepared and compared with a similar ester of δ-tocopherol. 5. Hydroxymethylation of δ-tocotrienol followed by reduction gave β-tocotrienol as a major product.
