摘要: 以九阡李(Prunus salicina Lindl.)果实为试材,利用HPLC及LC-MS对九阡李果实发育过程中有机酸及氨基酸组分与含量变化进行分析。结果表明,九阡李果实中含有5种有机酸及22种氨基酸,有机酸以奎宁酸、琥珀酸为主,分别占总有机酸的64.35%、33.16%,氨基酸以天冬酰胺及脯氨酸为主,分别占总氨基酸的33.69%、20.82%。在九阡李果实发育过程中,奎宁酸含量变化趋势为先缓慢降低再急剧升高再降低,琥珀酸含量呈先缓慢降低再缓慢升高再缓慢降低的变化趋势,且二者都在第二次膨果期达到峰值,天冬酰胺含量呈先急剧升高再急剧降低接着再缓慢降低的变化趋势,在发育前期含量达到峰值,而脯氨酸含量变化趋势为先急剧上升后急剧下降再缓慢升高,在成熟期达到峰值。

Abstract: Taking Jiuqian plum(Prunus salicina Lindl.) fruit as the test material, the contents of organic acids and amino acids in the fruit of Jiuqian plum were analyzed by HPLC and LC-MS. The results showed that there were 5 kinds of organic acids and 22 kinds of amino acids in Jiuqian plum. The main organic acids were quinic acid and succinic acid, accounting for 64.35% and 33.16% of the total organic acids, respectively. The main amino acids were asparagine and proline, accounting for 33.69% and 20.82% of the total amino acids, respectively. During the fruit development of Jiuqian plum, the content of quinic acid decreased slowly at first, then increased sharply and then decreased. The content of succinic acid first decreased slowly, then increased slowly and then decreased slowly, and both of them reached the peak at the second fruit expansion stage. The content of asparagine increased sharply at first, then decreased sharply and then decreased slowly, and reached the peak at the early development stage. The content of proline increased sharply at first, then decreased sharply, then increased slowly, and reached the peak at maturity.

Key words: Jiuqian plum(Prunus salicina Lindl.), fruit, organic acids, content of amino acid
