چکیده

gamma tocopherol content of 7 iranian sesame seeds (sesamum indicum l.) was determined by high performance liquid chromatography using c8 column and methanol, water and butanol as mobile phase. the gamma-tocopherol content varied from 563 to 1095 mg/kg in oil and 293 to 569 mg/kg in sesame seed and was in broad agreement with the codex range. a large variation was found in the concentration of gamma-tocopherol in oils of different cultivars and the karaj cultivar had more gamma-tocopherol content than the codex range with significant differences with the other cultivar. the gamma-tocopherol content was almost much more than the other literature values indicating the better nutritional value and oxidative stability in iranian sesame seed. the present study showed that iranian sesames are strong radical scavengers and can be considered as good sources of natural antioxidants for medicinal and commercial uses.

Effects of dietary sesame seeds on plasma tocopherol levels.

The tocopherols, the major vitamers of vitamin E, are believed to play a role in the prevention of human aging-related diseases such as cancer and heart disease, yet little is known concerning determinants of their plasma concentrations. Evidence from animal studies suggests that the dietary source of gamma-tocopherol can significantly affect plasma levels of this tocopherol as well as its func...

Effect of Roasting Process on Total Phenolic Compounds and γ-tocopherol Contents of Iranian Sesame Seeds (Sesamum indicum)

Sesame (Sesamum indicum L.) seed and oil have long been used widely as healthy foods to supply energy and prevent aging. Some of the main active anti-oxidative constituents in sesame seeds are γ-tocopherol and phenols. The purpose of this study was to investigate the relationship between roasting temperature and time with γ-tocopherol and total phenolic compounds (TPC) of sesame seeds when roas...
