Effect of Different Solvents on the Phytochemical Compounds of Sargassum sp. From Yogyakarta and East Nusa Tenggara

Sargassum sp. is one of the brown algae species. Two species of Sargassum were collected from Deere coast, Alor East Nusa Tenggara (NTT), and Krokoh beach, Gunung Kidul Yogyakarta. This paper compares the phytochemical screening of two species of Sargassum sp. by using three different polarity solvents. The two species of Sargassum sp. were dried, cut, and ground into powder. Their species were extracted successive using ethanol, ethyl acetate, and n-hexane. Phytochemical screening all of the extracts of Sargassum sp were performed with the spot tests as the standard methods. The ethanol extracts of Sargassum sp. from Yogyakarta and NTT showed the presence of saponins, tannins, terpenoids/steroids, and flavonoids. The ethyl acetate and n-hexane extract from the two species of Sargassum sp. have contents of tannins, terpenoids/steroids, and flavonoids. Tannins and terpenoids/steroids were major compounds in ethyl acetate extract both Sargassum sp. from Yogyakarta and NTT. Results showed that different solvents possibly different phytochemical compounds. Phytochemical of seaweed is influenced by species, habitat, isolation method, and harvest season.
