Abstract: A method for determination of betalain was described by high performance liquid chromatrgraphy. Shim-pack vp- ODS column(4.6mm i.d. ×150mm, 5μm)was used and mobile phase was MeOH:H 2O-HAc(20: 80) with flow rate of 0.7ml/min. The eluate was monitored at λmax=535nm . The linearity was obtained over the range of 0.0641 ~3.206mg/ml ( r = 0.9999).The determination limit was 0.06 4μg/ml.The average recovery of sample was in the range of 97.58% ~102.10%, with relative standard deviation of 1.13%. The method was proved to be a simple, rapid and reliable way to determine the betalain concentration.
