Abstract: In order to study the differences of amino acid contentamong different cultivars of Vitis vinifera L. fruits ,six cultivars of Vitis vinifera L. in Changli County of Hebei Province were used as the main test materials .The amino acid contents in Vitis vinifera L. fruits were quantitatively analyzed by amino acid automatic analyzer. The results showed that the main amino acids in Vitis vinifera L. fruits were Glu, Arg, Pro and Asp. The total amount of amino acids in Vitis vinifera L. fruits was 368.33~197.17 mg/100g, and the content of essential amino acids was between 84.36~41.88 mg /100g, accounting for 17.88%~25.33% of the total amino acid content. Among the six cultivars, the difference of medicinal amino acid annonessenbial amino acid was significant. Glu was the most abundant amino acid among the 19 amino acids contained in the 6 varieties, among which the Glu content of Kyoho grape was 106.96 mg/100g, while the contents of Cys, Met and Tyr were few, which indicated that there were great differences in nutrition among different cultivars of Vitis vinifera L. fruits.
