【Abstract】 Objective To seek out the optimum extract technology of huangqi zhechong decoction. Methods Three levels in each of three factors( amount of water, decoction frequency and duration of decoction) were selected with orthogonal design. The conteats of astragaloside Ⅳ and polysaccharides served as indexes. Results The optimum extracting conditions were as follows. The amount of water was twenty times that of the drug, the decoction frequency was two ,and the duration of decoction was two hours. Conclusion This method of optimum design can guarantee the quality of huangqi zhechong decoction.更多还原
