目的采用高效液相色谱和薄层色谱技术 ,分别测定重楼中薯蓣皂苷元的含量。方法 采用 HPL C法 ,选用 ODS柱 ,流动相 :乙腈 -水 (90∶ 10) ,检测波长 :2 0 3 nm,柱温 :3 5℃ ;TL C法选用硅胶 G板 ,展开剂 :环已烷 -乙酸乙酯 (4∶ 1) ,测定波长 :610 nm,参比波长 :42 0 nm。结果 线性范围分别为 1.2～ 7.2 μg(r=0 .9998) ,0 .2～ 1.0μg(r=0 .9957)。平均回收率分别为 10 2 .2 % ,RSD=3 .3 9% (n=6) ;10 0 .9% ,RSD=2 .68% (n=6)。结论 两种方法均可用于重楼中薯蓣皂苷元的质量控制。

Object To determine the contents of diosgenin in Rhizoma Paridis by HPLC and TLC. Methods ODS column was used in HPLC with mobile phase: acetonitrile water(90∶10), detection wavelength: 203 nm, column temperature: 35 ℃; silica gel plate was used in TLC with developer: cyclohexane ethyl acetate (4∶1), scan wavelength: 610 nm, reference wavelength: 420 nm. Results The linear ranges of HPLC and TLC were 1 2 - 7 2 μg (r=0 999 8), 0 2 - 1 0 μg (r=0 995 7). The average recovery and RSD were 102 2%, 3 39% (n=6) and 100 9%, 2 68% (n=6) respectively. Conclusion Both of two Methods can be used for the quality control of diosgenin in Rhizoma Paridis
