摘　　要：以引种至湖南的4个菲约果品种果实为试材,分别运用常规方法和氨基酸分析仪对其主要营养成分和游离氨基酸含量进行分析。结果表明:4个品种果实可溶性糖、Vc、可滴定酸含量差异显著,而可溶性固形物含量差异不显著;不同品种间苏氨酸、谷氨酸、丙氨酸和脯氨酸的含量差异较大,其他氨基酸差异不明显。其中,4个品种果实可溶性固形物都在11.19%～12.69%;可溶性糖含量以"Unique"最高;Vc含量从高到低依次为"Mammoth","Unique","Coolidge","Triumph";可滴定酸以"Mammoth"最高,"Coolidge"最小;总氨基酸含量以每100 g计量,最高为"Coolidge"(243.5 mg),其次为"Mammoth"(229.3 mg),最低为"Triumph"(113.8 mg)。The four Feijoa sellowiana varieties were introduced to Hunan as the materials,the main nutritional components were using conventional methods and the free amino acids composition was analyzed by automatic analyzer.The results showed that there was significant difference in soluble sugar,Vc,titratable acid in the verieties,but there was no significant different in soluble solid content;different varieties had significant difference in ammonia in the threonine,glutamic acid,alanine and proline,but no significant difference in other amino acids soluble solids in the four varieties were between 11.19% and 12.69%;the soluble sugar content was the highest in ＂Unique＂;Vc contents were in the order of ＂Mammoth＂＂Unique＂＂Coolidge＂＂Triumph＂;the highest Titratable acidity was the ＂Mammoth＂,and the lowest was in ＂Coolidge＂ was the lowest;the total amino acid content was the highest in ＂Coolidge＂ 243.5 mg,followed by that in ＂Mammoth＂,229.3 mg,the lowest in ＂Triumph＂,113.8 mg in per 100g.
