“…Their identification was carried out by direct HPLC comparison with authentic markers and was based on co-chromatography at 290 nm for phenolic acids and flavanones and 340 nm for flavones. Response factors for the authentic markers and the concentration of compounds in each propolis sample were calculated according to Ogan and Katz (1981) and Annual Book of ASTM Standards (1983). Some of the authentic markers were commercially available; others were available in E. W.Јs laboratory.…”

“…The separation appears to be closely dependent upon the gradient program. Various wavelength settings (220-280 nm) of the UV detector were used although 215, 254, or 280 nm had been selected by earlier workers [1,2]. A setting of 270 nm was chosen because most of the compounds examined then gave a higher response.…”

“…Flavonoid identification was carried out by direct HPLC comparison of authentic flavonoids and was based on co-chromatography in 290 and 340 nm. Response factors for the authentic flavonoids and the concentration of flavonoids in each honey sample were calculated ( 26 , 27 ).…”
