摘要: 通过对兰州百合新鲜鳞片中水解氨基酸和游离氨基酸的分析,分析兰州百合鲜鳞片中18种水解氨基酸和20种游离氨基酸的种类及含量。研究表明:其水解氨基酸中精氨酸、谷氨酸、天冬氨酸、亮氨酸、甘氨酸、丝氨酸、赖氨酸、脯氨酸、缬氨酸含量较多,尤其是精氨酸和谷氨酸含量最大;游离氨基酸中也精氨酸含量较大。同时,本实验对百合的样品前处理方法做了一定程度的改良。

Abstract: In this study, an improved sample pretreatment method was used to analyze the composition of free and protein-bound amino acids in fresh scales of lily from Lanzhou. A total of 18 protein-bound amino acids and 20 free amino acids were identified and their contents were determined. The results show that the dominant protein-bound amino acids in Lanzhou grown lily were arginine, glutamic acid, aspartic acid, leucine, glycine, serine, lysine, proline and valine. Arginine and glutamic acid revealed the highest level among 18 protein-bound amino acids. Moreover, arginine was also a major free amino acid in lily scales.
