Compositions of Xanthorrhizol and Tocochromanol (Tocotrienol), and Methods of Use

摘要

A dietary supplement composition provided synergistic effects of xanthorrhizol and tocotrienol on malignancies. A blend of xanthorrhizol and delta tocotrienol achieved 69% growth suppression of melanoma, exceeding the sum of individual effects. In prostate cancer, 90% growth suppression was achieved by a blend of xanthorrhizol and delta tocotrienol; however, the same 90% of growth suppression was achieved by 3-fold xanthorrhizol and 1.8-fold delta tocotrienol respectively, which indicated synergistic impact of the two agents. Mechanisms of action for the anticancer property showed synergism of xanthorrhizol and tocotrienol-mediated cancer growth suppression was attributed to cell cycle arrest, at the G1 phase of cell cycle, and apoptosis. This novel dietary supplement combination of xanthorrhizol to tocotrienol (1:1 to 10:1) may provide benefits to individuals consuming it on a regular or periodic basis.
