摘要(Abstract):

[Objectives] To measure and analyze chemical composition of R. crenulata. [Methods] Taking R. crenulata in Lang County of Tibet as the research object,the routine nutritional components,trace elements and amino acid were determined,and the nutrition was evaluated by the international general evaluation method. [Results]The protein content of R. crenulata in Lang County of Tibet was 2. 08%,and fat was 5. 67%. Amino acid was incomplete amino acid,and Ile,Met + Cys were the first limiting amino acids of rhodiola root protein,while Leu was the second limiting amino acid of rhodiola root protein. The final amino acid score was 0. Magnesium,iron,zinc and other mineral elements were abundant,and there was no mercury,cadmium,lead and other heavy metals residues. [Conclusions]The research could provide a powerful basis for industrialization development of rhodiola.
