The chemical structures of P1 A was identified by complete acid hydrolysis, partial acid hydrolysis, periodate oxidation-Smith degradation, methylation analysis, IR and NMR. The results showed that P1 A had a backbone consisting rhamnose, mannose, glucose and galactose. The side chain possessed arabinose and xylose.
