AI Technical Summary
The prior art has not yet fully utilized the potential application of myrtle polysaccharide in the preparation of antibacterial and antioxidant drugs, especially in the inhibition of E. coli, Salmonella and Staphylococcus aureus and free radical scavenging.
The crude polysaccharide was extracted by water extraction and enzyme-assisted method, and protein was removed by combining Sevag method, and chromatography was used for separation and purification by DEAE-Sepharose Fast Flow ion exchange column and dextran gel column to obtain myrtle polysaccharide P5. The polysaccharide contains a specific monosaccharide composition and molecular weight, and has antibacterial and antioxidant activities.
Myrtle polysaccharide P5 significantly inhibited the proliferation of E. coli, Salmonella and Staphylococcus aureus and showed the ability to scavenge free radicals in vitro, especially in DPPH, hydroxyl and ABTS free radical scavenging.
