Abstract: A new method on separation and identification of flavonoids in plum was studied. Influence of microemulsion type on resolving power toward flavonoids was investigated with sodium dodecyl sulfate/n-C4H9OH/n-C7H16/H2O microemulsion as eluant on polyamide film. The flavonoids were separated entirely. Six flavonoid spots were obtained from fruit peel and three from pulp, but they were not identical. Compared with the general mobile phase composed of C4H9OH/CH3COOH/H2O(4:1:5), the sensitivity of detection was improved markedly and the results were satisfactory. This new chromatographic method is simple, accurate for separation and identification of flavonoids in plum.

Key words: plum, flavonoids, microemulsion, thin-layer chromatography
