A high performance liquid chromatographic method was developed for simultaneous determining the contents of galanthamine and lycorine in Lycoris Herb. The chromatographic analysis was carried out on a phenomenex-C18 column. The mobile phase was acetonitrile (A)-0.1% trifluoroacetic acid(TFA) (B) with gradient elution. The detection wavelength was set at 289 nm. The calibration curves for galanthamine and lycorine showed good linearity in the range of 0.5~10 mg/L(r=0.9999). The detection limits were 0.09 mg/L for galanthamine and 0.15 mg/L for lycorine at the signal-to-noise ratio of 3,and the average recoveries were 99.53% and 96.82%,respectively. The method is simple,rapid,accurate and suitable for the determination of galanthamine and lycorine in Lycoris Herb.
