Abstract:

To analyze the variations of sesame quality traits in different ecological environments, eight sesame varieties were planted in 13 experimental sites in China. The high performance liquid chromatography (HPLC) and near infrared spectrum (NIR) analysis were applied for quality evaluation. The results showed that the average contents of oil, oleic acid, linoleic acid, palmitic acid, sesamin and sesamolin of the 8 sesames were 55.43%, 38.88%, 46.16%, 8.63%, 4.56 mg/g and 2.70 mg/g, respectively. The oil content gradually increased and then decreased with the increase of latitude. Xiangyang site had the highest oil content, with the average of 57.50%, and it was significantly higher than those in other experimental sites. The average contents of sesamin and sesamolin in Ili site were the highest with the average of 5.58 mg/g and 3.60 mg/g, respectively. The sesamin and sesamolin contents in other experimental sites firstly increased and then decreased from north to south. It suggested that Xiangyang site was more suitable for planting sesame with high oil content, while Ili site was suitable for cultivating sesame with high sesamin and sesamolin contents.

Key words: sesame, quality traits, oil content, lignan, ecological environment
