Screening of Tocopherol and Tocotrienol Diversity in <i>Cornus</i> Species Seeds Using a Sustainable Extraction Protocol.

ABSTRACT: Although not major crops, Cornaceae species, the dogwood family, are common in most continents and used primarily as ornamental crops, though some are used for food as well. In the present study, tocochromanol-tocopherol (T) and tocotrienol (T3)-contents were analyzed in the seeds of twenty-four Cornus species belonging to six Cornus subgenera. Given the substantial number of samples included in this study, we applied a fast extraction protocol using an ethanol and ultrasound treatment and systematically compared its performance with that of a conventional alkaline saponification method. Total tocochromanol content ranged from 0.78 to 21.63 mg 100 g^-1 dry weight (dw) seeds in C. kousa and C. controversa, respectively. The highest mean total tocochroma
