摘　　要：对湛江的鲜辣木叶及其辣木茶产品中的生物活性成分及主要营养成分进行分析。结果显示:以干质量计,鲜辣木叶和辣木茶的总游离氨基酸含量分别为(27.72±1.07)、(26.04±0.83)mg/g,γ-氨基丁酸(γ-aminobutyric acid,GABA)含量分别为(2.07±0.07)、(0.78±0.03)mg/g,L-Glu含量分别为(3.65±0.11)、(2.74±0.08)mg/g,蛋白质含量分别为(24.81±0.37)、(25.18±0.26)g/100 g,粗脂肪含量分别为(3.35±0.16)、(3.28±0.17 g/100 g),粗纤维含量分别为(18.42±0.44)、(22.51±1.04)g/100g。结果表明,辣木叶营养丰富,并富含游离GABA和L-Glu,具有开发新型富GABA功能性食品的极大潜力。The bioactive components and major nutrient component in the fresh leaves and tea of Moringa oleifera in Zhanjiang were analyzed. Results showed that the total free amino acid containing in the fresh leaves and tea of Moringa olefera was （27.72± 1.07） mg/g and （26.04±0.83） mg/g respectively, and gamma-aminobu- tyricacid（GABA） containingwas（2.07±0.07）mg/gand（0.78±0.03）mg/ grespectively.Furthermore, highL- Glu content was also found in the fresh leaves and tea of Moringa o le i fe ra , which was （3.65 ±0.11） mg/g and （2.74±0.08） mg/g respectively. The fresh leaves and tea of Moringa oleifera were much rich of proteins, crude fats and crude fibers, which proteins containing was （24.81±0.37） g/100 g and （25.18±0.26） g/100 g respec-tively, crude fats containing was （3.35±0.16） g/100 g and （3.28±0.17） g/100 g respectively, and crude fibers containing was （18.42±0.44） g/100 g and （22.51±1.04） g/100 g respectively. The results indicated that the Moringa oleifera leave was a novel edible material with rich natural gamma-aminobutyric acid, and has great potential for the development of new GABA-enriched functional food.
