Objective: To establish a method for the determination of allantoin in Lithospermun zollingeri. Method: Separation and determination of allantoin were accessed by using an ODS-C18 column and a mobile phase of methanol-water at a ratio of 5∶95. The flow rate was 0.2 mL·min-1
temperature at 30 ℃ and detection wavelength at 210 nm. Result: A good linearity of allantoin was achieved in the range of 12.32-61.60 μg(r=0.999 9).The mean value of recovery was 98.1%
RSD was 1.55%. Conclusion: The method in this paper could provide an evidence for quality control of L. zollingeri and there is comparatively large difference of content of allantoin in L. zollingeri from different producing areas.
