This study will provide information for establishing a database of elite rice species with high functional components, and scientific evidence for the development of rice-based functional foods. Recently, there has been an obvious increase in the research on improving the rice quality both locally and internationally. Knowledge on different genetic, physiological and molecular factors that related to rice quality have gradually accumulated, many different varieties of rice have also been successfully bred. However, research on their functional components [e.g. tocopherols (T), tocotrienols (T3) and γ-oryzanol (GO)] remains limited. Although these functional compounds have been recognized to have high commercial value in the international market, their content and distribution in different plant parts of the local rice species and their physiological functions have not yet been analyzed and evaluated. Therefore, it is essential to have an insight study on these areas. Results of this study will provide basic foundation for the development of local rice-based functional foods, as well as enhancing the utilization efficiency and added value of rice.水稻生育醇生育三烯醇γ-谷維素免疫調節RiceTocopherolsTocotrienolsγ-OryzanolImmunomodulatory
