摘要
目的 :比较炮制对延胡索中延胡索乙素含量的影响。方法 :采用高效液相色谱法 ,色谱柱为C1 8,流动相为 [甲醇 水(70∶30 ) ]∶磷酸缓冲液 (1 0 0∶1 .8) ,检测波长为 2 80nm。结果 :各样品中 ,以醋制品中延胡索乙素含量为高。加样回收率为 99.0 7% ,RSD为 1 .81 % ,相关系数r =0 .9998。结论
Objective: To explore the effect of processing on the content of tetrahydropalmatine in Rhizoma Corydalis. Methods: HPLC was used with chromatographic condition included: C 18 column, mobile phase of methanol water phosphate buffer (70∶30∶1.8) and detection wavelength at UV 280nm. Results: The content of tetrahydropalmatine in the Rhizoma Corydalis processed with vinegar is the highest among all processed products. The recovery is 99.07% and RSD =1.81%, respectively. Conclusion: The processing with vinegar can increase tetrahydropalmatine content of Rhizoma Corydalis.
