The purpose of this study was to analyze phytochemistry contents and antioxidant activity  ofextracts from seagrass of Halodulepinifoliafrom solvents with different polarities. Parameters of research werephytochemical content, DPPH scavenging activity and reducing power. The result showed content of phytochemical compounds of ethanol extract seagrass were flavonoids, tannins, saponins, steriods andtriterpenoids. The use of ethyl acetate solvent showed phytochemical compounds were flavonoids, steroids and triterpenoids. For n-hexane solvent showed phytochemical compounds were steroids and triterpenoids.  The highest of antioxidant activity with DPPH method (IC₅₀) of H.pinifolia was 18.7 ppm with ethanol extract. The highest of reducing power of H.pinifolia was 1.749.
