Abstract: Angelic sinensis polysaccharides(ASP) were solubilized by sequential extraction both with hot water at 80℃(W- ASP) and 0.5% EDTA solution at room temperature(E-ASP). The results of suger analysis showed that W-ASP was mainly composed of GalA, galactose, arabinose, and a little part of rhamnose, mannose and glucose, whereas E-ASP contained high amount of glucose. W-ASP and E-ASP were orally administered to groups of mice. The results showed three W-ASP dosages raised higher number of white blood cell (WBC) and lymphocytes of exposed mice, and showed significant quatity-activity relationship. W-ASP and E- ASP enhance WBC and W-SCC simultaneously, but the effect of W-ASP showed better than that of E-ASP.
