Objectives: The aim of this study is to investigate anti-inflammatory activity of β-glucan (laminaran) of brown algae, Sargassum crassifolium which was extracted by using two different methods, β-glucan laminaran acid extract (LAE) and laminaran modified extract (LME). Methods: β-glucan (laminaran) of brown algae, S. crassifolium have been extracted using two different methods, namely, β-glucan LAE and LME. The edema reducing activity of the extracts was investigated with carrageenan- induced leg edema male of Rattus norvegicus as a model. Results: The swelling of edema was strongly inhibited by the treatment of LME with a percentage of 81.62% after 3rd hr. It also found that the size of edema were inhibited by all treatments with the value ranging from 25.49% to 81.68%. Smallest edema size was found on LME treatment, with a size of 0.68±0.09 mm where the control was about 0.92 mm. Furthermore, all β-glucan-treated mice showed lower edema size compared to control. Conclusion: It was obvious that all type of laminaran had anti-inflammatory activity. LME is the best method for production of β-glucan (laminaran) with high anti-inflammatory activity. Hence, in this study, we reported a new anti-inflammatory agent derived from S. crassifolium. © 2017 The Authors.
