In order to research the amino acid components and contents of Lonicera macranthoides Hand.-Mazz.introduced into the middle of the hilly area of Sichuan and evaluate their nutrition value,the contents of water,protein and amino acids in it were determined by the Oven,Kieldahl instrument and HITICHIL-8800 automatic analysis instrument,respectively.The results showed that the content of the protein was 14.37%.There were 17 kinds of amino acid,wherein 7 was essential amino acid for human.The contents of total amino acids,essential amino acids,nonessential amino acids,flavor amino acids and medicinal amino acids were 133.74 mg/g,59.42 mg/g,114.91 mg/g,and 80.29 mg/g,respectively.The ratio of essential amino acids to nonessential amino acids and essential amino acids to total amino acids were 0.79 and 0.44,respectively.Analyzing the amino acids via the amino acids ratio coefficient method,the amino acids ratio and the ratio coefficient were 0.97~1.32 and 70.76,respectively.The contents of amino acids of Lonicera macranthoides Hand.-Mazz.introduced to the middle of the Sichuan Hilly Basin were high and steady,the constitute of amino acids met the standard model.The nutritional value was balance.They could be used to eat directly or used as raw materials with high quality to develop health care products.
