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。

摘  要:
In this study,an improved sample pretreatment method was used to analyze the composition of free and proteinbound 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.
