Abstract [Objective] To establish an HPLC method for the simultaneous determination of eleutheroside E content in the roots and stems of Acanthopanax brachypus from different habitats.[Method] Separation was carried out on Agilent TC-C 18(2) column (250 mm×4.6 mm,5 μ m).The mobile phase consisted of acetonitrile -0.1% phosphoric acid water (16∶84) with a flow rate of 1.0 mL/min.The detection wavelengths was 220 nm, volume of injection was 10 μL, and the temperature of column was set at 30 °C.[Result]Eleutheroside E showed a good linear relationship between 8.0-160.6 μg/mL and the peak area ( r =0.999 6), the average recovery rate was 98.62%, and the RSD was 0.50%.[Conclusion]The method is convenient, stable and reliable, which is suitable for the determination of the content of eleutheroside E in the roots and stems of Acanthopanax brachypus Harms, and can be used as the quality control index of Acanthopanacis brachypus radix et rhizoma seu caulis.

倒卵叶五加 (Acanthopanacis brachypus radix et rhizoma seu caulis)为五加科植物短柄五加 Acanthopanax brachypus Harms [Eleutherococcus brachypus (Harms) Nakai]的干燥根和根茎或茎,分布于我国西北地区的陕西、甘肃、宁夏,主治体虚乏力、腰膝酸软、脾肾阳虚、失眠多梦、食欲不振等病症[1-2]。倒卵叶五加是陕西的特色植物药,有很高的药用及研究价值[3]。现代药理学研究表明,倒卵叶五加具有增强免疫力、抗疲劳、保护缺血心肌、抑制血小板聚集、抗血栓形成和抗氧化等药理作用[4-10]。目前,对倒卵叶五加的研究主要集中在苷类和黄酮类化合物方面,对其具体化学成分的研究以及质量控制的文献比较少。倒卵叶五加药材的质量控制指标单一,主要以紫丁香苷的含量测定为标准[11-12]。近年来,采用HPLC法对刺五加、糙叶五加中刺五加苷E含量的测定均有研究报道[13-15],而倒卵叶五加中刺五加苷E的含量测定鲜见报道。通过该试验的前期研究发现,短柄五加根、茎中刺五加苷E的含量高于紫丁香苷。为了进一步有效控制倒卵叶五加的质量,该研究选择以刺五加苷E为检测指标,试图建立稳定、高效的倒卵叶五加药材中刺五加苷E的测定方法,并比较不同产地、不同部位的短柄五加中刺五加苷E含量的高低,以期为其资源的开发利用与药材质量控制提供科学依据。
