To determine and analyze the amino acids in different parts of Hippohae rhamnoides' branches and leaves,the experiment used amino acid analyzer and found that there were 17 amino acids in different parts of Hippohae rhamnoides' branches and leaves,including 2 acidic amino acids,3 basic amino acids,12nutral ones,as well as 9 medical amino acids,among which 7 were essential amino acids,2 semiessential amino acids and 8 none-essential amino acids.Different contents existed in different parts,with a descending order of leaves＞mix of branches and leaves＞ small branches＞middle sized branches and big branches; there was an obvious difference between the content of amino acids of different verities and the included essential amino acids,the total amino acid content for the small Hippohae rhamnoides was 159.61 mg/g,that for the mix of branches and leaves was 92.27 mg/g; while that for male Hippohae rhamnoides leaves was 117.48 mg/g,that for the mix of branches and leaves was 91.00 mg/g,42.13 mg/g and 1.27 mg/g more than that of the small Hippohae rhamnoides; however,the amino acid content in small branches,middle sized branches and big branches reduced 30.12 mg/g,8.50 mg/g and 6.18 mg/g respectively ; the essential amino acid content in small Hippohae rhamnoides and the mix of branches and leaves were respectively 60.80 mg/g,34.14 mg/g,while that for the male Hippohae rhamnoides' leaves and the mix of branches and leaves were respectively 43.86 mg/g and 32.57 mg/g.The study laid a foundation for the research on amino acid content in Hippohae rhamnoides' leaves and branches,and providing a scientific reference for the development and utilization of Hippohae rhamnoides' leaves.
