ABSTRACT
Objective To optimize the extraction technology of alginic acid in Laminaria japonica Aresch. Methods The influence of the amount of solvent, the extraction time and temperature (3 factors) on the alginic acid content and yield was investigated by orthogonal test L9(34), and carried on to inspect the methodology. Result The optimum extraction condition was A1B1C2, that was adding 30 times solvent (1%Na2CO3), whisk extracting for one hour at 60 ℃. Conclusion The temperature is the most important factor. The content of alginic acid decrease obviously at above 60 ℃. The optimum extraction technology is reasonable.
