Parboiled rice bran oil was obtained using supercritical CO2 under different conditions of temperature (2°C to 40°C) and pressure (25 to 200 bar). In this study the experiments were carried out with two separators coupled to the extractor. The temperature levels in the first separator were 25°C and 40°C and in the second it was maintained constant at 2°C. The pressures in the first separator we...
0308-8146/$ see front matter Published by Elsevier doi:10.1016/j.foodchem.2010.01.057 * Tel.: +1 808 959 4343. E-mail address: [email protected] Phytochemical compounds (tocopherols, tocotrienols, and squalene) were measured in seven macadamia cultivars harvested from four locations on Hawaii island to establish whether these compounds enhance the oxidative stability of roasted kernels. ...
There is growing evidence that inflammation may be one of the causal factors of osteoporosis. Several cytokines such as IL-1, IL-6, RANKL, OPG, and M-CSF were implicated in the pathogenesis of osteoporosis. These cytokines are important determinants of osteoclast differentiation and its bone resorptive activity. Anticytokine therapy using cytokine antagonists such as IL-receptor antagonist and ...
Changes in broiler chick tissue concentrations of lipid-soluble antioxidants immediately post-hatch.
The antioxidant protection of the chicken (Gallus gallus) embryo during incubation and early postnatal development plays an important role in chick viability. To assess the antioxidant capacity of the newly hatched chick, we determined the concentrations of vitamin A, vitamin E, carotenoids and coenzyme Q₁₀ in the major tissues of chicks which had been held in an incubator for up to 36 h post-h...
Aging results in a loss of muscle mass and strength. Myoblasts play an important role in maintaining muscle mass through regenerative processes, which are impaired during aging. Vitamin E potentially ameliorates age-related phenotypes. Hence, this study aimed to determine the effects of the tocotrienol-rich fraction (TRF) and α-tocopherol (ATF) in protecting myoblasts from replicative senescenc...
α-tocopherol succinate (α-TOS), γ-tocotrienol (GT3) and δ-tocotrienol (DT3) have drawn large attention due to their efficacy as radioprotective agents. α-TOS has been shown to act superior to α-tocopherol (α-TOH) in mice by reducing lethality following total body irradiation (TBI). Because α-TOS has been shown to act superior to α-tocopherol (α-TOH) in mice by reducing lethality following total...
This Application Note demonstrates the separation of eight tocopherol and tocotrienol compounds by supercritical fl uid chromatography (SFC) using the Agilent 1260 Infi nity Analytical SFC system. Calibration curves were generated for all compounds, and a real-life virgin olive oil sample was analyzed. The limits of detection and quantifi cation (LOD and LOQ) were determined as well as relative...
