Analysis on Amino Acid Component from Sagina japonica

To provide a scientific reference for further development and utilization of S.japonica,the amino acid in S.japonica was extracted with water and hydrolyzed with acid.The free and hydrolytic amino acids were measured by HITACHI 835-50Amino Acid Auto analytic Apparatus.Results:The contents of total amino acid,essential amino acid,semi-essential amino acid and drug-effective amino acids in S.japonica were high.The contents of free amino acid,hydrolytic amino acid was 452.28mg/100g and 8 070.57mg/100g,respectively;The contents of essential amino acid and semi-essential amino acid,drugeffective amino acids accounted for 24.17% and 43.37% of the total detectable free amino acids;The contents of essential amino acid and semi-essential amino acid,drug-effective amino acids accounted for 31.48%and 62.37% of the total detectable hydrolytic amino acids.S.japonicawas of abundant essential amino acid and drug-effective amino acids,and has rather high medical value.
