Abstract:
This paper was aimed to study the dynamic changes of San-Ao(SA) decoction in different compatibility of ephedrine hydrochloride,pseudoephedrine hydrochloride,amygdalin and glycyrrhizic acid.HPLC was used to simultaneously determinate the transfer rate of SA decoction of ephedrine hydrochloride,pseudoephedrine hydrochloride,amygdalin and glycyrrhizic acid.Kromasil C18 (4.6 mm×250 mm,5μm) column was selected with methanol and 0.1% phosphoric acid as a mobile phase to gradient.The flow rate was 1 mL·min-1.The column temperature was 30℃.The injection volume was 10μL.Ephedrine hydrochloride,pseudoephedrine hydrochloride and amygdalin were detected at the wavelength of 208 nm.The glycyrrhizic acid was detected at the wavelength of 250 nm.The results showed that the transfer rate of ephedrine hydrochloride in decoction was more than that of the single preparation.The transfer rate of pseudoephedrine hydrochloride was the highest in the combination of ephedra and bitter almond.The transfer rate of amygdalin was the highest in the combination of ephedra and bitter almond.The transfer rate of glycyrrhizic acid in decoction was more than that of the single preparation.It was concluded that there were dynamic changes in the boiling process during herbal decoction preparation.The effectiveness and stability of Chinese medicine should be improved according to these changes.
