目的 建立一测多评法同时测定竹节参中7种皂苷类成分的含量,并验证此方法在竹节参中应用的可行性与适用性。方法 采用HPLC法,以竹节参皂苷Ⅴ为内参物,建立人参皂苷Rg1、Re、Rb1,假人参皂苷RT1,竹节参皂苷Ⅳ、Ⅳa的相对校正因子(fs/i),并利用fs/i计算竹节参样品中成分的含量,同时用外标法测定各成分的含量,比较2种方法的差异。结果 人参皂苷Rg1、Re、Rb1,假人参皂苷RT1,竹节参皂苷Ⅳ和Ⅳa的fs/i分别为1.286 7、1.432 7、0.966 6、0.962 4、1.207 2、0.938 4。采用一测多评法与外标法得到的10批竹节参样品各成分含量无显著性差异。结论 建立的一测多评法准确性高,可用于竹节参皂苷类成分的定量分析和质量评价。

Objective To establish quantitative analysis of multi-components by single marker (QAMS) method for simultaneous determining the content of seven saponins in Panacis Japonici Rhizoma, and to evaluate the adaptation and application of QAMS method in the quality control of Panacis Japonici Rhizoma. Methods The relative factor (fs/i) of ginsenoside Rg1, Re, Rb1, pseudoginsenoside RT1, chikusetsusaponin IV and Ⅳa were established by HPLC method with chikusetsusaponin V as internal standard, which were used to calculate the content of seven saponins in Panacis Japonici Rhizoma. Meanwhile, external standard method (ESM) was used to calculate the content of seven saponins. The difference between QAMS and ESM was analyzed to evaluate the accuracy of QAMS. Results The fs/i of ginsenoside Rg1, Re, Rb1, pseudoginsenoside RT1, chikusetsusaponin IV and IVa were 1.286 7, 1.432 7, 0.966 6, 0.962 4, 1.207 2, and 0.938 4. There was no significant difference between the content of 10 batches of Panacis Japonici Rhizoma determined by QAMS and ESM. Conclusion The established QAMS method is accurate and can be used for quantitative analysis and quality evaluation of the content of seven saponins in Panacis Japonici Rhizoma.
