Abstract: The High-performance liquid chromatographic determination of crocin was described.Crocin was separated verywell on Tuner Packing Kromasil NH2 column by the use of acetonitrile:water (80:20) as mobile phase-under the flow rate of 0.8ml/min.It was detected at 440nm by UV-VIS spectrophtometer.the retention time was 12. 19min the detection limitwas 12.5ng.The average recovery rate was 99.34%,with a good stability and reproducibility,.
