The aucubin of Eucommia Ulmoide Oliver was determined by high performance liquid chromatography (HPLC) at 210 nm under the conditions as follows: ODS-C_(18) column,21% CH_3OHH_2O solution as mobile phase and the velocity of flow of 1.0 mL/min.

• 在 C18 反相色谱柱上；以21%25甲醇水溶液为流动相；流速为1.；0 mL/min；在波长210 nm处；用高效液相色谱法对杜仲提取液中桃叶珊瑚甙的含量进行了测定。
