%A Mahmiah, Mahmiah %A Andayani, Rina %D 2017 %T PHYTOCHEMICAL AND ANTIOXIDANT ACTIVITY of MANGROVE PLANT Soneratia sp. %K %X At the moment, plants use as medicine are mostly land plants, while plants derived from water such as mangroves have not received much attentions. Some of the mangrove plants that can be used as medicine are Acanthus ilicifolius, Avicennia alba, Avicennia marina, Avicennia offinalis, Bruguiera cylindrical, Bruguiera exaristata, Bruguiera gymnorrhiza, Ceriops tagal, Hisbiscus tiliaceus, Ipomoea pes-capre, Lumnitzera racemosa, Nypa fructicans, Pluchea indica Rhizophora apiculata, Soneratia sp., dan Sonneratia alba. The plants were utilized as antiasma, antidiuretic, antidiabetic, itch relieve, etc. Purnobasuki, 2004). One of the mangroves that are often found on the East Coast of Surabaya, East Java is Soneratia sp .. which is classed as true mangrove flora. Ethnobotanically, the wood and stem are used as traditional medicine as pain reliever. Based on research conducted by Mahmiah (2012)studying phytochemical aspect of Avicennia marina from east coast region of Surabaya,it was known that the stem and leaves of the plant contained phenolic compounds. Taking into account the existence of the waves and extreme weather conditions in the East Coast region of Surabaya, it was hypothesized that the secondary metabolite compounds produced by the plants would be different. Based on that hypothesis it was necessary to do a research on Soneratia sp. plant located on the East Coast of Surabaya with the aim of exploring the content of secondary metabolites from the stem of the plant. Methods that were used to accomplish that aim were (1) preliminary test; (2) phytochemical screening; (3) GC-MS analysis and (4) antioxidant test %U https://jurnal.unej.ac.id/index.php/prosiding/article/view/3889 %J UNEJ e-Proceeding %0 Journal Article %P 51-54%8 2017-01-27
