The experimental research is made on the immunologic function of Hunai polysaccharide in Pleurotus.

A water soluble carboxymethylated derivative (CM HNP) of Hunai polysaccharide (HNP)from the sclerotia of Pleurotus tuber regium (Fr.

In this paper,the extracting technique of sulfated polysaccharide is discussed and SPS is identified.

Extraction of sulfated polysaccharide was studied and the optimal condition chosen as extraction time 2 h, temperature 90℃, ratio of water to kelp 25.

The determination of polysaccharide content in sulfated polysaccharides separated from seaweeds by spectrophotometric analysis with H 2SO 4-Anthrone coloration was investigated methodogically.

Studies on the optimal technology factors of extracting sulfated polysaccharides from alga Gracilaria tenuispitata;

Research on ultrasonic acid extraction and properties of sulfated polysaccharides from gracilaria tenuistipitata;

Synthesis of Angelica Sinensis polysaccharide sulfate and their effects on splenocyte proliferation in vitro;

Anti-HIV activities of Achyranthes bidentata polysaccharide sulfate in vitro and in vivo;

Objective:To investigate the effect of chlorosulfonic acids on the synthesis of Angeli- ca polysaccharide sulfate (APS) and assess the APS activities against L6565 murine retrovirus.

AIM: Resercheres are more and more interested in polysaccharide sulphates for its anti-virus effects, especially for its anti-HIV activity.
