Abstract
Fucoidan extracted from aquatic plant Utricularia aurea was 1.3% of dry weight and comprised glucuronic acid 62.5% and fucose 4.98% of the crude extract and 28.74% of the fucose was sulfate. The fucoidan was investigated for antibacterial activity. The minimal inhibitory concentration (MIC) of crude fucoidan against Vibrio harveyi and Escherichia coli was 20 and 10 mg/ml. Moreover, the fucoidan had anticoagulant activity. The crude fucoidan had activated partial thromboplastin time (APTT) at 4.47 IU/mg.
