Determination of flavonoid and phenolic Acid contents of clover, cotton and citrus floral honeys.

Abstract

Authentic samples of clover, cotton and citrus honeys were selected and extracted from their hives placed in clover, citrus, and cotton farms. Their botanical origin was assured then they were extracted and analyzed for flavonoids and phenolic acids content. Results showed that the lowest percentage of authentic samples was found in cotton honey. Moreover, 93.00% +/- 3.00 of pollen grains found in clover honey samples were for clover, 16.25% +/- 3.18 of pollen grains found in cotton honey samples were for cotton and 32.50 % +/- 10.60 of pollen grains found in citrus honey samples were for citrus species. In addition, the flavonone hesperetin was found only in citrus honey samples with a mean content of 1.08 +/- 0.36 mg/100 g honey whereas, the flavanol quercetin was found in the three floral honeys. The phenolic acids (cinnamic acid and p-hydroxy benzoic acid) were detected in the three floral honeys with different quantities. It is recommended to use honey as a healthy alternative to sugar; also, to use hesperetin as a floral marker of citrus honey.
