ABSTRACT
AIM:
To establish the methods for determining ephedrina hydrochloridum,pseudoephedrine hydrochloride,puerarin,baicalin in Ganmao Soft Capsule (Herba Ephedrae,Radix Puerariae lobatae,Radix Scutellariae,Ramulus Cinnamomi,Radix Angelicae sinensis,Radix Angelicae dahuricae,etc.)METHODS:
Part 1(determination of ephedrina hydrochloridum and pseudoephedrine hydrochloride)The HPLC was carried out on kromasilTMC18 column(4.6 mm ? 250 mm,5 ?m) with acetonitrile-0.02 mol/L phosphoric acid solution(pH2.7)-triethylamine(2 ∶ 98 ∶ 0.1)as mobile phase,gradient elution.The detection wavelength was set at 207 nm.Part 2(determination of pueranin and baicalin)The HPLC was carried out on kromasilTMC18 column(4.6 mm ? 150 mm,5 ?m)with acetonitrile-water(11 ∶ 89)as mobile phase,gradient elution.The detection wavelength was set at 250 nm.RESULTS:
The average recoveries were 99.96% with RSD 1.25% ,98.41% with RSD 1.46% ,98.67% with RSD 0.91% ,99.30% with RSD 0.88% ,respectively.CONCLUSION:
The assay results demonstrate that the methods are simple,accurate and reproducible for quantification of four active components in Ganmao Soft Capsule.
