[Method ] Free amino acids in 30 kinds of fruit and vegetable samples were determined by automatic amino acid analyzer. [ResultJηle results showed that the free amino acids of longan , banana and jackfruit were the highest in the samples and red grape , pear, apple , pitaya , kiwifruit were the lowest. Litchi , longan , tomato and jackfruit contained higher -y -GABA. Banana , watermelon , cucumber, apricot contained higher threonine. Cherry , banana and sug? arcane contained h胁er serine.
