目的 :研究测定不同地区葛根中葛根素的含量差异。方法 :以山东、陕西、湖南等不同地区的葛根为原料 ,用高效液相色谱法测定其葛根素的含量。结果 :不同地区 12个品种的葛根素含量分别为 2 .81% ,4.6 1% ,2 .0 2 % ,6 .5 7% ,0 .5 5 % ,3.79% ,2 .2 2 % ,3.44% ,2 .81% ,4.2 8% ,7.78% ,6 .48%。结论 :不同产地葛根中葛根素含量差异较大 ,葛根药材收购及葛根素生产单位应予注意。
Objective : To study the difference of puerarin content in Radix Puerariae in different areas. Methods: Pueraria lobata was extracted from Shandong, Shaanxi, Hunan, and other regions. The content of puerarin was determined by high performance liquid chromatography. Results: The puerarin content of 12 varieties in different regions was 2.81%, 4.61%, 2.0%, 6.5%, 0.55%, 3.79%, 2.2%, 3.44, respectively. %, 2.81%, 4.28%, 7.78%, 6.48%. Conclusion : The puerarin content in Pueraria lobata varies greatly from place to place. Pueraria pueraria acquisition and puerarin production unit should pay attention.
