Abstract: The amino acid profiles of different parts of Salicornia bigelovii were determined using amino acid analyzer. The results showed that 16 common amino acids and 8 essential amino acids were found in the tender stems, stalks, and roots of Salicornia bigelovii in a balanced ratio, respectively. The protein content of tender stems was 16.53%, which was higher than other parts of Salicornia bigelovii. The essential amino acid content was 58.04mg/g, the ratio of essential amino acid content to non-essential amino acid was 0.59, and the SRC was 65.72, which were according with those recommended by FAO/WHO. The study showed that tender stems of Salicornia bigelovii had higher nutritional value with good prospects for the development and utilization.
