This study was to investigate the chemical content and antioxidant activity by the part of Salicornia herbacea as part of using Salicornia herbacea as materials of functional foods. On a basis of the materials, this study was to clarify the nutritional excellence, chemical composition, and antioxidant activity of Salicornia herbacea. From the result of this research above, it may be summed up as follows. The Salicornia herbacea used in the experiment contained the moisture and crude fiber in the stalks a lot, and the protein, fat, and ash in the branches more. As to the content of free amino acid, the content of arginine took in the branches and stems most. Then, it contained threonine, glycine, tryptophan, valine, isoleucine, and lysine, etc. in the branches a lot. Also, it contained threonine, glutamic acid, tyrosine tryptophan alanine, and isoleucine in the stalks a lot. It was shown to be contained of essential amino acids like isoleucine, leucine, threonine, valine, methionine, lysine, phenylalanine, and tryptophan in the branches and steams more. As to the content of fatty acid in Salicornia herbacea, it found out that it contained the unsaturated fatty acid more than the saturated fatty acid. It took the content of eicosenoic acid(20:1) in the branches and stalks most. And then, it contained linoleic acid(18:2), pehtadecenoic acid(15:1), palmitic acid(16:0), and oleic acid(18:1), etc. a lot. As to the antioxidant activity in Salicornia herbacea using the DPPH radical, it was shown to be existed in the largest antioxidant activity when the concentration of methanol extract from Salicornia herbacea was 1 mM. There was higher antioxidant activity than 100 ppm BHT used as control plot when the concentration of methanol extract from the stalks was 100 μM. From the result of experiment above, Salicornia herbacea contained the essential amino acid a lot. It will be possible to be used as natural antioxidants because it has excellent antioxidant effect. Therefore, this researcher concludes that it will be available in using it as materials of functional foods.
