The results obtained are as follows : The conditions of extraction by alkali oxalate are as follows : the sample acidtreated is extracted by 0.2 N sodium oxalate for two hours at 70℃. As the extractability of sodium oxalate compared with that of sodium carbonate for various brown algae, the extraction by sodium oxalate shows good results in case the sample used is easy to solve by alkali, namely sodium alginate extracted shows little colouring and its viscosity is high relatively, but its extracts shows decrease slightly. The other hand, in case the sample used is comparatively hard to solve by alkali, the extraction by sodium carbonate shows good results, namely sodium alginate extracted shows high viscosity and high yield but remarkable colouring of the extracts. But in case the extraction by sodium oxalate, the sample used do not solve nearly.
