TLDR
Calibration of all the minor components of palm as well as the individual components of Palm vitamin E was carried out and was found to be comparable to those analyzed by other established analytical methods.Abstract:
The application of supercritical fluid chromatography (SFC) coupled with a UV variable-wavelength detector to isolate the minor components (carotenes, vitamin E, sterols, and squalene) in crude palm oil (CPO) and the residual oil from palm-pressed fiber is reported. SFC is a good technique for the isolation and analysis of these compounds from the sources mentioned. The carotenes, vitamin E, sterols, and squalene were isolated in less than 20 min. The individual vitamin E isomers present in palm oil were also isolated into their respective components, alpha-tocopherol, alpha-tocotrienol, gamma-tocopherol, gamma-tocotrienol, and delta-tocotrienol. Calibration of all the minor components of palm as well as the individual components of palm vitamin E was carried out and was found to be comparable to those analyzed by other established analytical methods.read more

Tocopherol, tocotrienol and plant sterol contents of vegetable oils and industrial fats
TL;DR: In this paper, the NP-HPLC with fluorescence detection (tocols) and GC-FID (plant sterols) were used to determine the tocopherol and tocotrienol contents of 14 vegetable and 9 industrial fats and oils available on the Finnish market in 2005.

Metabolic profiling of lipids by supercritical fluid chromatography/mass spectrometry
TL;DR: A high-resolution, high-throughput analytical system based on SFC/MS is stated to be suitable for lipidomics because it is useful not only for the screening of lipid mixtures but also for the detailed profiling of individual components.
Journal ArticleDOI
A review of characterization of tocotrienols from plant oils and foods
TL;DR: Different techniques that are used in the characterization and purification of tocotrienols such as soxhlet and solid–liquid extractions, saponification method, chromatography (thin layer, column chromatography, gas Chromatography, supercritical fluid, high performance), capillary electrochromatography and mass spectrometry are listed.

Phenolic compounds, lycopene and antioxidant activity in commercial varieties of tomato (Lycopersicum esculentum)
TL;DR: In this paper, nine commercial varieties of tomato (Rambo, Senior, Ramillete, Liso, Pera, Canario, Durina, Daniella and Remate) were analysed for their lycopene content, content of phenolic compounds and antioxidant capacity.

Isolation and Identification of Novel Tocotrienols from Rice Bran with Hypocholesterolemic, Antioxidant, and Antitumor Properties
TL;DR: These tocotrienols significantly lowered serum total and LDL cholesterol levels and inhibited HMG-CoA reductase activity in chickens and had much greater in vitro antioxidant activities and greater suppression of B16 melanoma cell proliferation than alpha-tocopherol and known tocotrianols.

Supercritical fluid technology
TL;DR: The state-of-the-art in the science and technology of supercritical fluid processing is described in this paper, with a focus on developments in equations of state for binary and multicomponent mixtures (including polymer solutions), solubility measurements at near-critical conditions, measurements of critical properties of binary mixtures and their correlation with equations of states.

Effect of tocotrienols on the growth of a human breast cancer cell line in culture.
TL;DR: Results suggest that the inhibition of MDA-MB-435 estrogen-receptor-negative human breast cancer cells is due to the presence of tocotrienols in TRF rather than α-T, which is shown to be a form of vitamin E having an unsaturated side-chain.

Minor constituents of palm oil
TL;DR: The role played by phospholipids is frequently misunderstood because they can act in two ways, i.e. as an antioxidant synergist and a surface active agent to disperse impurities in oil.
