Necessary of the dissertation brown seaweed have been researched and obtained very good results Historically seaweeds are used as raw materials for many but up to now polysaccharides from the green seaweed in general and industrial applications such as food pharmaceutical and cosmetics ulvan from Ulva genus in particular is still pooly investigated. industry. Based on pigmentation seaweeds can be classified into three In this context we have chosen the topic Structural divisions as brown Phaeophyte red Rhodophyte or green algae determination of bioactive ulvan extracted from green seaweeds Chlorophyte . Vietnam has a coastline of about 3000 km with the Ulva lactuca and Ulva reticulata the purpose of the research are to climate varying from subtropical in the northern part to tropical in the study the structure of bioactive polysaccharides from green seaweed southern part of the country which is a rich source of seaweed species. to .
