Abstract:
AIM: To determine the contents of ephedrine、laetrile、glycyrrhizic acid and liquiritin in Huagai Powder traditional decoction and granule decoction(Herba Ephedrae,Semen Armeniacae Amarum,Radix et Rhizoma Glycyrrhizae,etc.) by HPLC. METHODS: An Agilent SB-C_(18) column was used for ephedrine,the mobile phase was acetonitrile-0.1% phosphoric acid(4∶96),detection wavelength at 207 nm;An Agilent XDB-C_(18) column was used for laetrile,the mobile phase was methanol-water(23∶77),detection wavelength at 215 nm;An Agilent XDB-C_(18) column was used for glycyrrhizic acid,the mobile phase was methanol-0.2 mol/L ammonium-acid(67∶33∶1),detection wavelength at 250 nm; An Agilent XDB-C_(18) column was used for liquiritin,the mobile phase was acetonitrile-0.5% acetic acid(20∶80),detection wavelength at 276 nm. RESULTS: There were discrepancies between traditional decoction and granules in the contents of four ingredients,the average contents in granules were more than those in the traditional decoction. CONCLUSION: The peaks of the four ingredients are(segregated)(effectively),and the method is simple,conveient,exact and has good reproducibility,the other ingredients do not have interferences for the determination.
