To obtain basic information for the quality evaluation, the introduced or domestic sesame seeds were investigated to measure proximate components (crude protein, ash, mineral and oil) and isolated by preparetive HPLC system for lignan contents. Although crude protein contents were the highest in Sudan sesame seeds, lipid, ash and mineral contents were not significantly (p0.05) different between introduced and domestic sesame seeds. Unsaturated fatty acids such as oleic and linoleic acids were the highest in the domestic sesame seeds. The mg content of domestic sesame seeds also was larger than that of introduced sesame seeds. A Ca content of domestic sesame seeds, however, was significantly (p0.05) lower than that of China. Lignan contents, the most important component known as antioxidant, were significantly (p0.05) higher in domestic sesame seeds than other sesame seeds tested. Our findings suggest that domestic sesame seed has the best quality in terms of the functional components.
