Although lignans of sesame seed, sesamolin and sesamin have been known as possessing an antioxidant activity, it is less known about their contents of the sesame cultivated in Korea. Collections of sesame cultivated in Korea were used for studies on their lignans content of the seed and fatty acids composition of the oil. The sesamin content of sesame seed with white-coat were 370.29 mg/100g seed, while that of sesame seed with black-coat were 246.58 mg/100g seed. Also, the sesamolin contents of sesame seed were 202.22 mg/100g seed in white-coat cultivars and 132.68 mg/100g seed in black-coat sesames. Hence, the lignan content of white-coat sesame cultivars was significantly higher than that of black-coat ones. Korean sesame cultivars also showed considerably higher sesamin content than sesamolin content in seeds. The correlation between sesamin and sesamolin contents was not recognized in Korean sesame cultivars. The stearic acid of white-coat sesame was significantly higher than that of black-coat one(p0.05).
