The quality and the nutritional ingredients and the functional activation of Nypa fruticans flower stalk was evaluated in this research. It consisted of 7.5% of water, 13.56% of crude protein, 0.84% of crude fat, 9.25% of crude ash, and 68.85% of carbohydrate. 12 kinds of minerals were identified, where the top 3 of them being K, Cl, and Na in order. There were a total of 15 types of amino acid analyzed, with the main amino acids of arginine 30.25%, aspartic acid 26.90%, and glutamic acid 17.12%. Total polyphenol content was 20,190.73 mg/100 g, and the total flavonoid content was 71.73 mg/100 g. The $IC_{50}$ for DPPH radical scavenging ability was $0.017{\pm}0.00mg/mL$ for Nypa fruticans Wurmb flower stalk, $0.672{\pm}0.01mg/mL$ for blueberry, and $1.282{\pm}0.03mg/mL$ for ginseng. The $IC_{50}$ for ABTS radical scavenging ability was $0.070{\pm}0.00mg/mL$ for Nypa fruticans Wurmb flower stalk, $2.918{\pm}0.13mg/mL$ for blueberry, and $4.131{\pm}0.24mg/mL$ for ginseng. For this reason, it is considered that containing plenty of polyphenol and antioxidant, Nypa fruticans Wurmb is related to antiinflammation. This research will contribute to production of functional foods and high value materials using Nypa fruticans Wurmb.
