| Abstract: | To investigate the kinds and contents of the free amino acid（FAA） in three kinds of lily,the powder of lily was extracted in the distilled water.The conditions of extraction were studied.By orthogonal test,the results showed that the most appropriate conditions were as the following： extracting solvent was 5.0% acetic acid,the ratio of mass to liquid was 1：35,the extraction time was 3h and the extraction temperature was 70℃.The extracted samples of FAA in three kinds were measured by an Automatic Amino Acid Analyzer.There were 17 kinds of FAA,of which 7 were essential amino acids.The results showed that the main free amino acid in lily was arginine,which was about 60% of total FAA.FAA of lily showed high potential in medicine and nutrition. |
