Abstract:
Objective To explore the extraction technology of polysaccharides from Asterias amurensis and study their antibacterial activities in vitro. Methods Determined by spectroscopic methodology with phenol -sulfuric acid,the polysaccharide content was taken as inspecting index to select the extraction technology such as enzymatic hydrolysis,alkali,and alkali-enzymatic combined. Filter paper method was used to test the polysaccharides antibiotic activities in vitro. Results The optimum extraction technology was adding 2 times amount of 1 mol?L-1 sodium hydroxide,heating for 2h,under these conditions the greatest yield of starfish polysaccharides would be obtained which showed inhilitory effect on Staphylococcus aureus. Conclusion The alkal hydrolysis extraction technology is superior to the other methods; polysaccharides from Asterias amurensis showed antibiotic activity to some kinds of bacteria.
