　　Sesame lignans, including sesamin and sesamolin mainly, has been reported to have multiple functions beneficial to health.This study analyzed sesamin and sesamolin contents in 215 sesame lines from a core collection in China by HPLC.The results showed the core sesame germplasm in China have a broad variation from 2.49 to 18.01 mg/g with average 8.54 mg/g in total of sesamin and sesamolin.On average, sesamin contents in the lines with white seed coat color were significantly higher than in those samples with brown, yellow and black color (P < 0.01).The lines with black seed coat had highest CV (coefficient of variation) followed by those with brown, yellow and white.The correlation coefficient between sesamin and sesamolin in the sesames with different seed coat color ranked as white (R =0.23) < yellow (R =0.44) < and brown (R =0.72) < black (R =0.77).The results of this study provided valuable background information on sesame germplasm in China and identified potential genotypes for breeding high sesamin or sesamolin cultivars.
