Characterization and analysis of sesamolinol diglucoside in sesame seeds

Abstract

A new lignan glucoside was isolated from defatted sesame seed flour and its structure was established as sesamolinol diglucoside [2-(3-methoxy-4-(O-β- D-glucopyranosyl (1→6)-O-β-D-glucopyranoside)phenoxyl)-6-(3,4- methylenedioxyphenyl)-cis-3,7-dioxabicyclo-(3.3.0)-octane] by mass and nuclear magnetic resonance spectroscopy. A quantitative analysis of 65 sesame seed samples showed that this sesamolinol diglucoside ranged from <5 to 232 mg/100 g of seeds (98 ± 57 mg/100 g) with no difference between white and black sesame seeds.
