Antioxidant profile of buckwheat honey from the republic of Moldova

Abstract

The honey is a natural substance, whose therapeutic qualities have been developed in parallel with human evolution. Its antioxidant and antiinflammatory properties are due to the polyphenolic compounds. The purpose of this study is to identify and quantify the phenolic compounds and the FTIR spectrum from buckwheat honey from the Balti region, Republic of Moldova. The radical scavenging activity of honey was 83% in the DPPH• reaction system. Phenolic compounds from honey were identified by HPLC-MS method, the significant concentrations being lignans, catechins, isorhamnetin, rutin, apigenin and luteolin. FTIR analysis revealed both the carbohydrate profile in buckwheat honey and the presence of active compounds.
