Objective:To optimize extraction technology of polysaccharides from Dendrobium nobile and to measure its effect on the splenocyte proliferation.Method:Based on the single factors test
such as extraction time
extraction temperature and solvent to material ratio were optimized by orthogonal test L9(34).MTS/PMS assay was used to measure the splenocyte proliferation.Result:The optimal technology conditions were as follows:extraction temperature was set at 90 ℃
and extraction time was 2.5 h with ratio of 45:1.D.nobile crude polysaccharide(DNCP) and D.nobile purificatory polysaccharide(DNPP) resulted in a significant increase of lymphocyte proliferation.DNCP and DNPP could also enhance the effect of Con A-induced T lymphocyte proliferation and the stimulation index of LPS-induced B lymphocytes.Conclusion:Under these conditions the polysaccharides yield of D.nobile was up to 2.80%.DNCP and DNPP can effectively increase lymphocyte proliferation and enhance the effect of Con A
