Isolation and bioactivity screening of chemical constituents extracted from gracilaria changii

Gracilaria changii has been extracted and fractionated to obtain the ethanol, diethyl ether, ethyl acetate, buthanol extracts and polysaccharide. In this research, isolation and separation of chemical compounds have been carried out by various solvent and chromatographic methods. The structure of...
