摘要: The tocotrienol-rich-fraction (TRF) from palm oil, being tried as a more economical and efficient substitute for alpha-tocopherol, significantly inhibited oxidative damage in vitro to both lipids proteins rat brain mitochondria induced by ascorbate-Fe2+, the free radical initiator azobis(2-amidopropane)dihydrochloride (AAPH) photosensitisation. observed inhibitory effect was time- concentration-dependent. At low concentration of 5 microM, TRF can inhibit proteins. seems be mainly due gamma-tocotrienol lesser extent alpha- delta-tocotrienols. effective than alpha-tocopherol. This fraction oil considered natural antioxidant supplement capable protecting against thereby ensuing adverse alterations.
