Efecto del consumo de aceite crudo de palma o maíz sobre la oxidación in vitro de la HDL plasmática de conejos: Oxidación in vitro de HDL de conejos. AVFT [online]. 2007, vol.26, n.2, pp.115-119.

We investigated the in vitro susceptibility to copper-induced oxidation of the rabbits HDLs fed during 3 months with 10 % supplementary diet of crude palm oil or corn oil. The isolated HDLs by ultracentrifugation were dializated  and oxidated following the addition of 10 µM Cu²⁺, the conjugated dienes were analysed by spectroscopic monitoring at 234 nm. The kinetics change of lag-phase of the group feed with crude palm oil was longer (145 min) with respect to the group feed with corn oil (94 min) (p<0,05). We concluded that the consumed of the crude palm oil, rich in carotenes and tocotrienols, increase the protection in vitro of HDLs unsatured fatty acids oxidation.
