Abstract

Sesame Sesamum indicum L is one of the oldest oilseed crops grown in India and worldwide This oilseed crop has high nutritional value due to the presence of antioxidants such as lignans and tocopherols Screening of oilseed germplasm for important nutritional attributes is of prime importance in quality breeding programs In the present study the content of lignans sesamin and sesamolin and tocopherol homologues α γ and δtocopherol was determined using reverse phase HPLC RPHPLC in 143 sesame lines collected from diverse agroecological zones of India Exploitable levels of sesamin sesamolin γ and δtocopherol was observed in the studied sesame lines Sesamum indicum cultivar CO 1 introgressed line MKN 9 and Sesamum malabaricum showed high values for sesamin Exotic and indigenous accessions of S indicum EC 542283 and IC 132176 IC 204681 IC 204773 showed high sesamolin contents Cultivars AKT 64 AKT 101 Phule til 1 and Tapi A showed high values for γ and δtocopherol The average content of sesamin and sesamolin was 086 and 050 mg g−1 seed respectively The average tocopherol content 292 μg g−1 seed found in this study indicates the presence of a high amount of tocopherol in Indian sesame germplasm Superior genotypes of sesame reported in this study could be utilized in sesame breeding programs for enhancing oil yield and nutritional attributes
