Pharmacognostical studies on Heshouwu (Polygoni Multiflori Radix): textual research, quality evaluation and processing chemistry investigation

Objective To investigate the proliferative effects of different extract of Polygonum multiflorum Thunberg on spleen lymphocytes of mice. MethodsProliferation of T cells was induced by Con A. The proliferation ability of lymphocyte was detected by XTT assay. ResultsThe butanol and ethyl acetate extract from Polygonum multiflorum Thunberg can both accelerate proliferation of spleen lymphocytes directly and increased proliferation of T cells of mice induced by Con A. The chloroform extracts can inhibited the proliferation of spleen lymphocytes and T cells induced by Con A. Conclusion The different active fractions of Polygonum multiflorum Thunberg has different immune regulating activities,it indicated that Polygonum multiflorum Thunberg probably has double immunoregulation.
