摘　　要：目的确定野葛块根和藤茎的最佳采收年限,为野葛的野生资源保护和规范化种植供理论依据。方法采用HPLC法测定不同生长年限的野葛块根及藤茎葛根素含量。结果一年生块根和藤茎葛根素含量均最低,分别为1.82%和1.25%;而五年生葛根和二年以上藤茎含量最高,分别为7.86%和3.02%。结论采收五年生的野葛块根入药和二年生以上藤茎较好。Objective To determine the harvesting years of Pueraria lobata and provide scientific basis for protection of wild resources and planting of Good Agriculture Process （ GAP}. Methods Puerarin was determined by HPLC from different growth years of Pueraria lobata. Results For one-year old block-root and the vine of Pueraria lobata, the contents of puerarin were 1.82% and 1.25% respectively , but in the five-years old block-root and over two-years old vines, puerarin was the highest, reached to 7.86% and 3.02% respectively.
