The methacrylic acid-based RDP in combination with the optimised purification method allowed the extraction of α-tocopherol with 94% recovery. The synthesised polymer was used successfully to extract α-tocopherol together with other essential minor components of sunflower oil without any pre-treatment step.
Preservation of alpha-tocopherol in sunflower oil by herbs and spices. Rosemary, thyme, turmeric, sage, oregano and cumin extracts (2000 mg.kg-1) delayed rancidity (P < 0.01) and preserved alpha-tocopherol (P < 0.01). Some preservation was observed with clove extract but coriander and cardamom extracts were pro-oxidants.
α-tocopherol is the most active form of vitamin E and its concentration in sunflower oil is found to be in the range of 500–600 mg/kg (Warner and Mounts 1990) whereas concentration of α-tocopherol in olive oil is in range of 100 mg/kg-200 mg/kg (Gliszczyńska-Świgło et al.
In relation to the sunflower oil, it was observed that the alpha-tocopherol concentration was similar to the concentration found on the food table composition of the United States Department of Agriculture (2008) and in Lechner's paper et al. (1999) (411.0 mg/kg and 425.0 mg/kg, respectively).
Isolation of tocopherol and sterol concentrate from sunflower oil deodorizer distillate. The sunflower oil deodorizer distillate was composed of 24.9% unsaponifiable matter with 4.8% tocopherols and 9.7% sterols, 28.8% free fatty acid (FFA) and 46.3% neutral glycerides. The isolation technology included process steps such as biohydrolysis,...
Soybean, LEAR and com oils contained low levels of a-tocopherol,from 12 to 20 mg/100 g oil; whereas, sunflower oil contained an average of 61 mg/ 100 g oil which is 92% of the total tocopherol. ,8-Tocopherol was present in only small amounts in soybean, sunflower and com oils. No ,8-tocopherol was detected in LEAR oil.
Seed oil is also known to be highly rich in tocopherols content. Vitamin E is an important dietary nutrient for humans, and which is mainly synthesized from plant extract and seed oil extraction. Tocopherol mainly contains the alpha, beta, delta and gamma isomers.
The overall recovery of tocopherols and sterols after hydrolysis, esterification and distillation were around 70% and 42%, respectively, of the original content in sunflower oil deodorizer distillate.

Sunflower Oil is Natural Herbal body massage Oil. 100% Pure, Solvent-Free and Non-Refined. Contains proteins vital for building & repairing tissues and reduces risk of skin diseases
scavenging, while n-BUT showed highest FRAP; TPC was found highest in crude extract. Generally, BHA and a-tocopherol are more protective in stabilizing the sunflower oil. P. porrigens ’ SFIII and SFIV had short-term protective effect in secondary oxidation for -year; whilst
Mixed Tocopherols are a clear, viscous, brownish-red oil with a mild vegetable oil-like odor. Prolonged exposure to oxygen, light, and/or certain chemicals may result in a gradual darkening. As such it is recommended that normal storage practices for vegetable oils be followed.
chromatographic conditions for simultaneous determination of retinol and alpha tocopherol in corn oil nanoemulsion. The sample was analyzed on an Inersil C8-3 (4.6 mm×150 mm), using methanol and water as mobile phase with gradient elution system and detected at 292 and 325 nm for alpha tocopherol and retinol, respectively by spectrophotometer.
Numerous foods provide vitamin E. Nuts, seeds, and vegetable oils are among the best sources of alpha-tocopherol, and significant amounts are available in green leafy vegetables and fortified cereals. Most vitamin E in American diets is in the form of gamma-tocopherol from soybean, canola, corn, and other vegetable oils and food products
Vitamin E infused in Sunflower Oil at a ratio of 1:10. Appearance. Liquid colourless to pale yellow. Odour. Characteristic – mild, slight. INCI Name. Helianthus Annuus Seed Oil and Tocopherol. CAS Number. Not available. EC Number. Not available
Vegetable oils, including wheat germ, sunflower, safflower, corn, olive and soybean oils, are very good sources of alpha-tocopherol. For example, 1 tablespoon of safflower or sunflower oil provides about 5 milligrams, while a similar amount of canola oil contains 2 milligrams and soybean, olive and corn oils contain between 1 and 2 milligrams per tablespoon.
Changes of Total Tocopherol and Tocopherol Species During Sunflower Oil Processing Article (PDF Available) in Journal of the American Oil Chemists' Society 88(1):127-132 · January 2010 with 309 Reads
Sunflower seeds come in 2 types: the non-oil seeds that are eaten as confectionery products after roasted with the shell or without the shell as kernels, and the oilseeds that are processed into oil and meal which is a by-product of sunflower seed oil extraction primarily used as an ingredient in livestock feed rations.
