摘　　要：为评价荔枝的营养价值,采用全自动氨基酸分析仪测定广东、广西、海南和福建4个产区共5个妃子笑荔枝果汁样品的氨基酸组分。结果表明:妃子笑荔枝果汁富含氨基酸组分,不同产区样品的氨基酸组分总量介于341.51～455.42mg/100mL之间,其中广西钦州产区样本的氨基酸组分含量最高为455.42mg/100mL,广东阳西产区样本的氨基酸组分含量最低为341.51mg/100mL;5个样品妃子笑荔枝果汁的氨基酸组分总量平均为396.38mg/100mL;其中γ-氨基丁酸为妃子笑荔枝果汁中的主要氨基酸,其平均含量为104.69mg/100mL,占氨基酸组分总量的26.57%;其次为丙氨酸,平均为67.37mg/100mL,占16.87%。基于对荔枝果汁中氨基酸组分的初步评价,认为荔枝是一种具有富含γ-氨基丁酸的潜在功能性食品资源。In order to evaluate the nutritional value of litchi（Litchi chinensis Sonn.）,amino acid compositions of five kinds of litchi juice of Feizixiao from major production regions such as Guangdong,Guangxi,Hainan,and Fujian province in China were analyzed by using an automatic amino acid analyzer.The results showed that litchi juice was rich in amino acid components.The total content of amino acids in samples from Qinzhou in Guangxi province was the highest,which was up to 455.42 mg/100 mL;in contrast,the total content of amino acids in samples from Yangxi of Guangdong province was the lowest,which was 341.51 mg/100 mL.The average content of total amino acids in five juice samples was 396.38 mg/100 mL.Theγ-amino-n-butyric acid（GABA） and alanine were the major amino acids with an average content of 104.69 mg/100 mL for GABA and 67.37 mg/100 mL for alanine.Based on the analysis of GABA content in litchi juice,litchi is a potential material for the development of GABA-rich functional food products.
