反相高效液相色谱法对豆薯不同部位鱼藤酮含量的测定与分析OA

This study used RP-HPLC to determine the rotenone content in Pachyrhizus erosus.The re-sults showed that the seeds had the highest rotenone content,reaching 4.8 wt％in the white variety from Yuqing,Guizhou,followed by fibrous roots,leaves,and stems.The rotenone contents in seeds and stems increased with maturity,whereas that in leaves decreased.No rotenone was detected in the edi-ble tuberous roots.However,rotenone was present in the fibrous roots.Therefore,the fibrous roots should be removed before use as animal feed.The seeds,stems,and leaves of Pachyrhizus erosus can be used for rotenone extraction.This study provides a scientific basis for the resource utilization of Pachyrhizus erosus.
