Abstract: Objective To determine constituents of amino acids in the aerial parts of Broussonetia papyrifera.Methods The constituents composition of the ammo acid of the aerial parts of Broussonetia papyrifera were analysised by Hitachi 835-50 automatic amino acid analyzer (Hitachi 835-50) Results All the aerial parts of Broussonetia papyrifera contain at least 16 kinds of amino acid, the main amino acids are asparlate、glumatic acid、 arginine、valine、proline and lysine, and seven of them are essential amino acids for human body.The fruits, leaves, male inflorescences and the aggregate fruits of Broussonetia papyrifera contain 12.44、24.35、15.88、11.94 gram total Amino acids and 3.92、9.95、9.7、3.27gram essential amino acids in 100 gram of sample powder respectively.The content of amino acids of leaves and fruits of Broussonetia papyrifera varies with different growing stages.Conclusion The leaves and aggregate fruits of Broussonetia papyrifera contain rich amino acids, which reserved to be further exploited.
