Determination of Phenolic Acids in Natural and Farms Honey of Khyber Pakhtunkhwa, Pakistan

摘要

This study was focused to evaluate the phenolic acids in natural combs honey, branded and unbranded honey of Khyber Pakhtunkhwa, Pakistan by HPLC technique, using UV-visible detector. Five phenolic acids (chloroganic acid, gallic acid, vanallic acid, benzoic acid and syringic acid) were identified and quantified in 18 honey samples. The phenolic acids contents were found higher in all natural honey's samples as compared to branded and unbranded honey. Among the natural honey's sample, the maximum concentration (4.26 mg/100 g) of phenolic acids was found in palosa (Acacia) honey while minimum 1.93 mg/100 g) in bekerr (Justicia) honey sample. Similarly the maximum concentration (2.78 mg/100 g) was found in langanese honey, while minimum (0.71 mg/100 g) in varsatile honey sample. In unbranded honey maximum concentration (2.46 mg/100 g) was found in Beera (Ziziphus) honey, while minimum (0.62 mg/100 g) in Palosa (Acacia) honey sample. It is evident from this study that, processing of honey may effects the phenolic acid contents of honey,
