Amino acid composition and content were compared and the nutritional value of chrysanthemum at different altitudes in Baoxing County were discussed. Amino acids were extracted by Hydrochloric Acid Hydrolysis Method and was determined it by automatic amino acid analyzer. Results showed that all chrysanthemum contain 16 kinds of amino acids,7 kinds of essential amino acids. The amount of amino acids and essential amino acids were increased with altitude. Leucine is the first limiting amino acid and threonine is the second limiting amino acid. The number of essential amino acids met with the FAO / WHO amino acid pattern spectrum were increased first and then decreased with the altitude. All chrysanthemum protein ha high digestion and utilization,but didn't reach the ideal protein standards made by the FAO / WHO. The total amounts of functional amino acids increased with the altitude,the tasted were getting better as well. According to the FAO / WHO amino acid pattern spectrum,the chrysanthemum at 2219. 2 m was the best; and according to the ideal protein standards,the better one was at 2329. 3 m. The chrysanthemum showed best digestion and protein utilization. The best taste and functional amino acids of the chrysanthemum was at 2598. 7 m.
