| Abstract: | Total phenolic acid contents of seventeen different types of Chinese honey were analysed by Folin-Ciocaileu colorimetry The results showed that the linear range of standard curve was 0 002～0 012 mg/mL, the average recoveries of catechin were 98 6%,98 4% and 101 8% with corresponding RSD of 0 64%,0 81% and 0 58% respectively Total phenolic acid contents of ten types of diluted Chinese honey samples varied from (133 0±8 3) to (1?484 6±67 0)?μg/g as Catechin equivalent Buckwheat honey(North of Shaanxi province) contained significantly higher total phenolic acid content compared with other Chinese honey samples |
