High Performance Liquid Chromatographic Determination of Antioxidant Lignan Glycosides in Some Varieties of Sesame

The difference in the distribution of sesamin, sesamolin, sesaminol glucosides and sesamolinol components in representative varieties of sesame were compared. Quantitation was achieved by HPLC determination using an external standard. The most abundant lignan glucosides in sesame seed were sesaminol triglucoside. The content of sesaminol triglucoside in 100 g seeds ranged from 14.1 to 91.3 mg with an average value of 68.4 mg; that of sesaminol diglucoside from 8.2 to 18.3 mg with an average value of 11.6 mg; and that of sesaminol monoglucoside from 5.4 to 19.5 mg with an average value of 8.3 mg. The total content of sesaminol glucoside was 88.3 mg in 100 g of sesame seeds. Also, the sesamolinol content in 100 g sesame seed ranged from 17.6 to 28.5 mg, the average being 20.5 mg. Within
