Abstract: With the aim of better characterizing the phytochemical components and antioxidant capacity of strawberry and of screening the genetic source with high nutritional quality, the quality parameters (soluble solid content, titratable acidity and firmness) and nutritional parameters (total phenols, total flavanoids, anthocyanins, vitamin C, vitamin E and antioxidant capacity) of 6 strawberry cultivars were determined and compared. Results indicated that total phenols were the most important materials for antioxidant capacity of strawberry. Meanwhile, total anthocyanins and vitamin C were also the major contribution factors. Based on the quality and nutritional parameters, Queen Red had the most satisfactory nutritional quality among six different strawberry genotypes. Therefore, genotype is the determinant for the nutritional quality of strawberry.

Key words: strawberry, nutritional quality, antioxidant capacity
