摘　　要：目的:探究不同生长年限对黄芪药材中黄酮及皂苷类成分含量积累的影响,为确立药材的最佳采收年限奠定理论基础。方法:采用高效液相色谱法测定采集的不同生长年限黄芪药材中黄酮及皂苷类成分的含量。结果:不同生长年限黄芪药材中黄酮及皂苷类成分含量存在明显差异,同一地区生长年限越长其含量相对较高。结论:随着生长年限的增加,黄芪药材中黄酮及皂苷类成分含量大致呈逐年升高趋势,生长年限对这两类成分的积累影响较大。Objective： To study the effects of different growing years on the accumulation of flavonoids and saponins in Astragali Radix,in order to offer evidence to determine the most appropriate harvest time. Methods： HPLC method was developed for the determination of the contents of flavonoids and saponins. Results： The contents of flavonoids and saponins in different growing years of Astragali Radix existed obvious differences,the longer growing,the content was relatively higher. Conclusion： With the increase of growing years,the contents of flavonoids and saponins are roughly rising year by year,the harvest time has a great influence on the accumulation of the compositions.
