Analysis of Free and Protein-Bound Amino Acids in Fresh Scales of Lily (Lilium davidii var unicolor) from Lanzhou

Abstract

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.

Key words: Lilium davidii var unicolor, amino acid, analysis
