Abstract:

The purpose of this study is to separate and identify ethyl acetate extract of propoils from Nanyang, central
China’s Henan province by reverse phase-high performance liquid chromatography-diode array detector compled with
electrospracy ionization-tandem mass spectrometry (RP-HPLC-DAD-ESI-MS-MS). A method for detecting 10 flavonoid
reference standards was established using RP-HPLC-DAD. The linear correlation coefficients for the ten flavonoids were
0.998 2–0.999 9 and the recoveries were 93.40%–103.69%. The RSDs of precision, stability, and spiked recovery were all
less than 5%. The ethyl acetate extract of Henan propolis was analysed by RP-HPLC-DAD-ESI-MS-MS. Totally 11 flavonoids
were identified including quercetin, apigenin, kaempferol, isorhamnetin, chrysin, pinocembrin, galangin, pinobanksin, pinobanksin-
3-O-acetate, pinobanksin-3-O-propionate, pinobanksin-3-O-butyrate and two phenolic acids and their esters.

Key words: propolis, reverse phase-high performance liquid chromatography-mass spectrometry (RP-HPLC-MS), flavonoids, phenolic acids and esters
