Simultaneous determination of twenty-five polyphenols in multifloral and cactus honeys using solid-phase extraction and high-performance liquid chromatography with photodiode array detection

Simple and accurate high-performance liquid chromatography–photodiode array detection method has been proposed for simultaneous separation and determination of 25 polyphenol compounds, including 10 phenolic acids, nine flavonoids, and six other phenols in 17 varieties of multifloral and cactus honey of Yemen. Multiwalled carbon nanotubes were used as solid-phase adsorbent for extraction of the polyphenols from honey samples. The total amount of...
