This ginseng species was first recorded in Quang Binh province with the name of Bo Chinh ginseng. Scientists from Quang Binh University and Tue Lam high tech Agriculture Co. Ltd restored this ginseng. Nowadays, model of this ginseng cultivation is being expanded by many provinces and initially brought high economic efficiency. In order to have a basis to build a nutritional product chain for it, we conducted an analysis of amino acid content in the rhizome of Bo Chinh ginseng. The study results showed that there are up to 18 types of amino acids in hydrolyzed samples and 16 types of free amino acids, including 9 essential amino acids, the hydrolyzed amino acid content is 6.786% and the total free amino acid content is 1.5% of ginseng root weight, aspartic content is the highest. The essential amino acid content accounts for 28.93% of the total amino acid content. The hydrolyzed amino acid content is 6.786% (essential amino acid accounts for 2.228% of the ginseng weight and nearly 33% of the total amino acid content) and the total free amino acid content is 1.5% of the ginseng (essential amino acids account for more than 25% of the total free amino acid content), of which the aspartic content is the highest (more than 23% of the total amino acid content).
