摘　　要：以蕨麻为试材,采用原子吸收法、高效液相色谱法等多种现代物理仪器方法和化学常规方法测定蕨麻块根中有效成分,研究分析了不同采收季节的蕨麻块根中的有效成分。结果表明:不同季节采收的蕨麻块根中营养成分均丰富、齐全;春季采收的蕨麻块根淀粉、多糖含量较高,鞣质含量低,适口性好,可作为保健型药材开发利用;秋季采收的蕨麻块根中多糖、鞣质、总黄酮等有效成分含量较高,可作为药用型药材开发利用。Taking Potentilla as test material, active ingredients were determinated in Potentilla by atomic absorption speetrometry,HP1.C（high performance liquid chromatography） and other modern instruments of physical method and chemical method,effective components in different harvest seasons in potentilla were analyzed. The results showed that Potentilla roots in different harvest seasons were rich in nutrients, complete; the starch and polysaccharide content of spring harvest Potentilla roots were higher with low tannin content, it could be used as development and utilization of health-medicine;the polysaccharide, tannins and total flavonoid of autumn harvest were higher, it could be used as medicinal herbs exploitation.
