Structural characterization and antiviral effect of a novel polysaccharide PSP-2B from Prunellae Spica
文摘

A novel polysaccharide, PSP-2B, was isolated from aqueous extracts of Prunellae Spica.

PSP-2B was a sulfated polysaccharide with molecular weight approximately 32 kDa.

The framework of PSP-2B was speculated to be a branched arabinogalactomannan.

PSP-2B exhibited interesting activity against herpes simplex virus.
