Abstract
Objectives: Ephedra sinica and Wolbigachul-tang which contains Ephedra sinica are used to treat obesity in Korean medicine. The aim of this study was to analyze the quantities of ephedrine alkaloids by high-performance liquid chromatography.
Methods: The analysis was performed using a YMC-Triat C18 column with operating at 25°, and UV detection at 210 nm. The mobile phase used a gradient flow with 0.1% H3PO4 in water and acetonitrile. Specificity, linearity, precision, accuracy, limit of detection, and limit of quantification were measured for validation anaylsis. This method was applied to analyze the quantities of ephedrine alkaloids in Ephedra sinica and Wolbigachul-tang.
Results: The concentration per Ephedra sinica (gram) of ephedrine and pseudoephedrine in Ephedra sinica decoction are 4.74±0.22 mg and 2.19±0.10 mg, respectively and in Wolbigachul-tang decoction are 6.39±0.34 mg and 2.97±0.21 mg, respectively. The retention time of ephedrine was 23.6 min and that of pseudoephedrine was 25.8 min, and norephedrine and methylephedrine were not detected.
Conclusions: In conclusion, analyzed the concentration of ephedrine alkaloids in Ephedra sinica and Wolbigachul-tang by the developed validation method.
