H. Chi et al., DETERMINATION OF COMPONENTS IN PROPOLIS BY CAPILLARY ELECTROPHORESIS AND PHOTODIODE-ARRAY DETECTION, Journal of chromatography, 680(2), 1994, pp. 593-597
The capillary electrophoretic separation of components in propolis, a
commonly used natural medicine, was investigated. Optimum conditions f
or the separation were established. Photodiode-array detection permitt
ed the rapid identification of the components in the samples analysed.
The determination of these components, including caffeic acid, dimeth
ylcaffeic acid, isoferulic acid and quercetin, was performed on a comm
ercial propolis sample.
